Abstract:

Access to credible building product performance information throughout the design and construction process is critical to enable project development, vet product selections, ensure as-built quality, and successfully complete construction. This is common knowledge and part of common practice for nearly all parties involved in design and construction. The sources of such information can range from vernacular to formal – from common practice to special reference. The focus of this paper is one of the more formal or specialized information sources, performance testing, as well as how such performance testing information can be better used. This paper’s goals are to familiarize the reader with performance testing and to depict a new kind of valuable informational tool (digital ecology). Reference to pertinent nomenclature, description of a real world example, and detailed description of such an informational tool’s values will be provided.The major content of this paper was developed during project-based work and firm-funded internal research at point b design, ltd. over approximately the previous 4 years. The phrase ‘digital ecology’ as herein used is a new concept proposed by the author. The analysis contained in this paper could be applied to the field of operations and maintenance as it is herein applied to design and construction; however, operations and maintenance is beyond the scope of this paper and may be addressed in future papers. It is my hope that this paper will contribute to tangible and real improvements of the built environment via continued, positive development within academic and professional practice.

Abstract:

Ever since Hench et al. first discovered bioactive glass in 1969, extensive interest was created because of the materials ability to chemically bond with living tissue. In this project the bioactivity of three different compositions of the bioactive glass Na2O-CaO-SiO2 have been studied. The compositions of the different glasses were A (25% Na2O, 25% CaO and 50% SiO2), B (22.5% Na2O, 22.5% CaO and 55% SiO2) and C (20% Na2O, 20% CaO and 60% SiO2). Their bioactivity was tested through biomimetic evaluation, in this case by soaking samples of each glass in simulated body fluid (SBF) and phosphate buffered saline (PBS). After soaking, the samples were analyzed with Scanning Electron Microscopy (SEM), Energy-Dispersive X-ray Spectroscopy (EDS), Grazing Incidence X-ray Diffraction (GIXRD) and Fourier-Transform Infrared Spectroscopy (FTIR) to analyze if hydroxyapatite formed on the glass surfaces. Both the A and B glass showed bioactivity in SBF and PBS, while the C glass did not. Further work is necessary to determine which of the A and B glass has the highest apatite formability and the reason why the C glass were not bioactive.

Abstract:

Cellular materials are often used as impact/blast attenuators due to their capacity to absorb kinetic energy when compressed to large strains. For such applications, three key material properties are the crushing stress, plateau stress and densification strain. The difficulties associated with obtaining these mechanical properties from dynamic/impact tests are outlined. The results of an experimental investigation of the quasi-static and dynamic mechanical properties of two types of cellular materials are reported.The dynamic tests were carried out using Hopkinson pressure bars. Experimentally determined propagation coefficients are employed to represent both dispersion and attenuation effects as stress waves travel along the bars. Propagation coefficients were determined for 20 mm and 40 mm diameter viscoelastic PMMA pressure bars and for elastic Magnesium pressure bars. The use of the elementary wave theory is shown to give satisfactory results for frequencies of up to approximately 15 kHz, 8 kHz and 30 kHz for the 20 mm and 40 mm diameter PMMA bars and the 23 mm diameter Magnesium bars respectively. The use of low impedance, viscoelastic pressure bars is shown to be preferable for testing low density, low strength materials.The quasi-static and dynamic compressive properties of balsa wood, Rohacell-51WF and Rohacell-110WF foams are investigated along all three principal directions. The dynamic properties were investigated by performing Split Hopkinson Pressure Bar (SHPB) and Direct Impact (DI) tests. In general, the crushing stress, the plateau stress and the densification strain remain constant with increasing strain rate of the SHPB tests. However, a dynamic enhancement of the crushing stress and plateau stress was revealed for balsa wood and Rohacell-51WF. In contrast, the plateau stresses of the Rohacell-110WF specimens are lower for SHPB than quasi-static tests. From the DI tests, it is shown that compaction waves have negligible effect on the stresses during dynamic compaction of along and across the grain balsa wood at impact speeds between approximately 20-100 m/s. Alternatively, the proximal end stresses of both Rohacell-51WF and 110WF foams increase with increasing impact velocity, following the quadratic trend predicted by 'shock theory'. This indicates that compaction waves are important for the case of Rohacell foam, even at low impact velocities.

Abstract:

The main cause of spacecraft failures is due to the harsh space environment; therefore, rigorous testing of materials used in modern spacecraft is imperative to ensure proper operation during the life span of the mission. Enhancing the capabilities of ground-based test facilities allows for more accurate measurements to be taken as it better simulates the environment to which spacecraft will be exposed. The range of temperature measurements has been significantly extended for an existing space environment simulation test chamber used in the study of electron emission, sample charging and discharge, electrostatic discharge and arcing, electron transport, and luminescence of spacecraft materials. This was accomplished by incorporating a new two-stage, closed-cycle helium cryostat, which has an extended sample temperature range from 450 K, with long-term controlled stability of -7Pa) that can simulate diverse space environments. These existing capabilities include controllable vacuum and ambient neutral gases conditions (< 10-7 to 10-1 Pa), electron fluxes (5 eV to 30 KeV monoenergetic, focused, pulsed sources ranging from 10-4 to 1010 nA-cm-2), ion fluxes (<0.1 to 5keV monoenergetic sources for inert and reactive gases with pulsing capabilities), and photon irradiation (numerous continuous and pulsed monochromatic and broadband IR/VIS/UV [0.5 to 7 eV] sources). The original sample mount accommodates one to four samples of 1 cm to 2.5 cm diameter in a low-temperature carousel, which allows rapid sample exchange and controlled exposure of the individual samples. Multiple additional sample mounts have been added to allow for standalone use for constant voltage measurements, radiation induced and conductivity tests, as well as extended capabilities for electron-induced luminescent measurements to be conducted using various material sample thickness in the original existing space environment simulation test chamber.

Abstract:

With rising interest in metal additive manufacturing and, specifically, in powder bed fusion processes, it is essential to understand relevant process parameters and the behavior of powders used in such processes. At the time of writing, the flow behavior of powders is in the spotlight whereas little research into the spreadability of a powder is being conducted. While the two characteristics are related, powders that are being spread are subject to different force loads which are not present during the simple flow of a powder. This work develops a testing system capable of qualitatively and quantitatively assessing spreadability in metal powders. Seven gas atomized powders of varying size distributions and four different chemistries supplied by Uddeholms AB were used to examine the efficacy and accuracy of the system. Image analysis of the spread layers was found to be effective in measuring the areas of the powder layers. It was also possible to assess the quality of powder coverage in the layer in terms of defects, which were sensitive to process parameters such as layer thickness and rake speed. From measurements of the mass of powder in each layer, a layer density was calculated and shows greater sensitivity than powder coverage to changes in layer thickness parameters. The spreadability data collected were compared to relevant existing flowability metrics, including some derived from powder rheometry. Two metrics were created to assess how well the rheometry data can predict spreading behavior. Firstly, the change in area coverage as a function of rake speed correlated to an increase in basic flowability energy, both of which became less sensitive to rake speed at higher speeds. Finally, an equation was formulated to assess the gap that forms between the true height of a spread layer and the nominal layer thickness. This gap showed great sensitivity to the cohesion values attained from shear cell tests: highly cohesive powders produced larger spread layer gaps. This work is expected to contribute to moving toward a standardized method to attain a powder characteristic for spreadability.With rising interest in metal additive manufacturing and, specifically, in powder bed fusion processes, it is essential to understand relevant process parameters and the behavior of powders used in such processes.

Med ett ökande intresse för additiv tillverkning av metaller i allmänhet, och pulverbäddsprocesser i synnerhet, är det viktigt att förstå relevanta processparametrar och beteendet av pulver som används i sådana processer. I skrivande stund är flytbarheten i fokus, medan väldigt lite forskning görs på spridbarheten. Dessa två egenskaper är relaterade, men pulver som sprids utsätts för andra krafter vilka inte återfinns i simpla flytbarhetstester. I detta arbete utvecklas ett testsystem som är kapabelt till att undersöka spridbarheten kvalitativt och kvantitativt. Sju gasatomiserade pulver som tillhandahålles av Uddeholms AB, med varierande storleksfördelningar och fyra olika sammansättningar användes för att undersöka effektiviteten och noggrannheten av systemet. Bildanalys av de utspridda pulverlagren visade sig vara effektivt för att mäta arean av lagren. Det var också möjligt att undersöka kvalitén på pulvertäckningen med avseende på defekter, som visade sig vara känsliga för processparametrar så som lagertjocklek och rake-hastigheten. Från mätningarna av pulvermassan från varje lager kunde en lagerdensitet räknas ut, och denna visar större känslighet med avseende på processparametrar än pulvertäckningen. Spridningsdatan jämfördes med relevanta flytbarhetsmätningar, inklusive reometrimätningar av pulver. Två mätetal användes för att undersöka hur väl reometri kan användas för att förutse spridbarheten. Först användes ändringen i täckning som en funktion av rake-hastigheten korrelerat till ökningen av grundläggande flytbarhetsenergi, där båda parametrarna blev mindre känsliga vid högre rake-hastigheter. Sedan formulerades en ekvation för att redogöra för glappet mellan den verkliga höjden av ett pulverlager och den nominella lagertjockleken. Detta glapp visade stor känslighet för koherensen som mättes med hjälp av skjuvcellstest: koherenta pulver gav större glapp i spridlagren. Detta arbete förväntas bidra till utvecklingen av en standardiserad metod att undersöka spridbarhet hos pulver.

Abstract:

The use of cellular foam as a core material in light-weight structural applications is of considerable interest. However, advances in this technology have been limited due to the lack of information concerning the macroscopic material behavior of cellular foams. Of particular interest in the design of composite structures is the shear modulus, G, of the core material, which must be established with a high degree of accuracy. Current ASTM test methods for shear modulus determination were researched and found inadequate for testing cellular foam materials. The difficulty in testing foam and the inaccuracies associated with the standard test methods established the need for the development of a test method for these materials. The test method (test fixture and test procedure) developed for cellular foam materials is presented. The design of the test fixture and the finite element analysis performed to determine fixture accuracy are discussed in detail. Additionally, the test procedure is presented, as well as the results for the 32 tests performed.

Full text

Abstract:

The mechanics of grinding and polishing are fundamentally similar: both rely on randomly oriented diamond particles for material removal. The basic difference between the processes is that grinding uses a fixed abrasive, while polishing uses a loose abrasive. The difference in material removal mechanisms for grinding (brittle) and polishing (ductile) of optical materials is intriguing, especially in view of the similarities between the two processes. This similarity brings up an important question: can the material removal mechanism be changed from one of fracture to one of plastic deformation in the grinding of brittle materials? This possibility of a brittle-ductile transition in material removal is the central concern of microgrinding research, and is the subject of this paper.

Full text

Abstract:

Optical materials such as ceramics and glass are not usually amenable to machining operations because of their poor fracture toughness and attendant brittleness. However, production of optical surfaces using machine tools has the advantage that a complex form can be deterministically generated, for example, an aspherical surface. Consequently, considerable interest exists in developing single-point diamond turning and diamond grinding technologies for brittle materials. Very high stiffness, precision machine tools must be used to control the process and, in particular, avoid surface fracture damage. Under appropriate conditions, "ductile-regime" machining conditions can be achieved wherein the material removal appears to take place by ductile shear rather than brittle fracture. However, material removal mechanisms underlying ductile-regime machining processes are not well understood. The work reported here is aimed at gaining a better understanding of the mechanisms that underlie these processes. The development and verification of models for single-point diamond turning will be addressed.

Abstract:

The tutorial will be on the company owner's view in the selection of materials and processes for the manufacture of optical components, coatings, and sub-assemb1ies. It will start with the receiving of a quotation from the customer. Depending on the quantity requirements, either prototype quantities or large volume production quantities, it will have to be determined how to buy raw materials and a decision will have to be made on temporary or hard tooling. We will show a comparison of different manufacturers suppling the same type of raw materials and their impact on quality, price, and delivery. We will discuss interfacing between engineering or designers and manufacturers. A cost comparison will be made between single elements and large volume production. We will also discuss the effect of tolerances on pricing. One would also have to look if test equipment is available or will have to be modified or possibly purchased. Specifications will be discussed to establish coating parameters. We will also discuss the impact that quality, environmental requirements, and change orders have on delivery.

Abstract:

A fundamental evaluation of issues affecting the fabrication of infrared-transmitting materials has been initiated as part of the Center for Optics Manufacturing's (COM) Process Science effort. The study, which will investigate the effect of process conditions on resulting material properties and optical quality, is aimed at improving the database of manufacturing related parameters which will lead to increased fabrication efficiency. The objectives and goals of the program will be reviewed.
