In this study, four reinforced concrete frames were produced two storeys, one bay and 3D in 1/6 geometric scale was tested. Since the studied frame was the external frame of the structure, brick infill wall with a window opening was also included. The first specimen was the reference specimen and contained no strengthening and no brick wall. The second specimen was contained brick wall.

Abstract:
One of the greatest drawbacks to predicting the behaviour of bonded joints has been the lack of reliable data on the mechanical properties of adhesives. In this study, methods for determining mechanical properties of structural adhesive were discussed. The Young’s modulus, Poisson’s ratio and tensile strength of the adhesive were tested by dogbone specimens (bulk form) and butt joint specimens (in situ form). The shear modulus and shear strength were test by V-notched specimens (bulk form) and thick adherend lap-shear (TALS) joint specimens (in situ form). The test results show that the elasti

A novel adaptive displacement-controlled test setup was developed for fatigue testing on mini specimens.

Abstract:
Abstract Laboratory qualification of corrosion inhibitors for oilfield applications is a multistage process consisting of a suite of performance and compatibility tests mimicking the field conditions as closely as possible. The final and often decisive step in this sequence is typically a longer-term test focusing on the performance of corrosion inhibitor candidates against localized corrosion. Despite its fundamental importance in the decision-making process, there is currently no consensus in the industry about the definition of localized corrosion and the pass/fail criteria for tested inhib

Abstract:
Determination of mechanical properties with the use of sub-sized specimens is topic a high interest nowadays. The application of the sub-sized samples is quite wide for all cases where only limited amount of the experimental material is available such as evaluation of additively manufactured products properties, residual life of in-service components, properties determination of developed nano-structured materials, assessment of dilatometric samples used for thermal and thermo-mechanical treatment development, local properties of components, weld joints and so on.

Abstract:
High velocity contact-impact problems are of great interest in industries related to aerospace, mechanical and civil engineering. Ductile fracture often occurs in such applications. Taylor rod impact tests are used as experimental and numerical tests for determining the mechanical behaviour of materials subjected to high strain rates. At sufficiently high velocities, a significant plastic deformation leading to fracture is observed. In this paper, ductile fracture in Taylor rod made of AISI1045 steel is simulated using a continuum damage mechanics model. Simulations are performed for the veloc

Abstract:
This project is a follow up to the project titled "Effects of Tensile Loading on Remaining Strength of Corroded Casing." The objective is to test additional samples of corroded casing that will fail at typical storage well operating pressures and transfer the developed technology to MFL vendors for use in storage fields. A test matrix of 13 specimens was developed and tested. The test specimens consisted of natural corrosion and machined defects. Prior to testing: � the specimen material was characterized with tensile, Charpy V-notch, hardness, and chemical tests and � the test specimens were

Abstract:
A laboratory testing program on rock salt specimens was performed using test conditions that are consistent with the stresses that are experienced near the surfaces of salt caverns during storage operation. The proposed work effort focuses on improving the methodology for defining the onset of dilation for rock salt. Geomechanical studies use dilation criteria to assess the potential for salt damage that can lead to spalling in the cavern roof and/or walls and subsequent damage to the cavern or hanging string. This constraint is often the one that limits the minimum gas pressure in a natural g

Abstract:
The American Association of State Highway and Transportation Officials (AASHTO) T 23 standard provides instructions for making and curing concrete test specimens in the field. However, further research is needed to compare the strength of the field-cured specimen with the strength of the actual in-place concrete item. The purpose of this research is to build an understanding of the current state of the practice for field-curing methods. Specifically, the research team conducted a literature review and questionnaire survey to identify the selection criteria and details of field-curing methods.

Abstract:
A variety of mechanical property tests are performed in the design, construction and maintenance phase of a pipeline. Most of the tests are performed by use of small-scale specimens with size typically in the range of a few inches to tens of inches (1 in = 25.4 mm). There are numerous test labs capable of performing most small-scale tests. These tests can be performed effectively under a variety of conditions, e.g., test temperature, strain rate, and loading configuration. More importantly, most routine small-scale tests are performed in accordance with national and international standards, en
