Abstract:
AbstractThe blade deformation caused by aerodynamic and centrifugal loads during operating makes blade configurations different from their stationary shape. Based on the load incremental approach, a novel pre-deformation method for cold blade shape is provided in order to compensate blade deformation under running. Effect of nonlinear blade stiffness is considered by updating stiffness matrix in response to the variation of blade configuration when calculating deformations. The pre-deformation procedure is iterated till a converged cold blade shape is obtained. The proposed pre-deformation met

The research showed the hereditary nature of the strain granular materials’ accumulation. Therefore, the authors used integral calculus for analytical solution of the residual deformation’s dependence on the number of repeated loads and on the magnitude of the main stresses. Moreover, the authors obtained the solution in the form of logarithmic and power functions, which associated the accumulated deformation

This study experimentally investigates the influence of surface deformations on contact conductance when two dissimilar metals are brought into contact. Most relations between the contact conductance and the load use the surface hardness to characterize surface deformations. This inherently assumes that deformations are predominantly plastic.

When the pressure is less than the structural strength, elastic deformations appear. With a pressure of greater structural strength, elastic and residual deformations appear.

Shallow foundations can provide the most economical solution for supporting small-scale structures. The design approach is quite simple considering the ultimate bearing capacity and working-load settlement. Research has shown that settlement calculations, determined using a linear-elastic approach, usually govern the design but this approach is inappropriate because soil is highly non-linear, even at small strains. The result is that signifi cant discrepancies are observed between predicted and actual settlements. This uncertainty has seen the development of settlement-based approaches such as

Nearly one-third of all pharmaceutical substances on the market are able to sorb water into their crystal lattices to form hydrates, which can often compromise stability during processing and/or storage[1]. The tendency of a hydrate to lose its water of crystallization during the manufacturing process of tablet compression is of particular concern to formulation scientists. The amount of water freed as a function of increasing compaction pressure can be explained by the mobility of water within the compact.

Recent research has identified that current code level seismic demands used for diaphragm design are considerably lower than demands in real structures during a seismic event. However, historical data has shown that steel deck diaphragms, common to steel framed buildings, perform exceptionally well during earthquake events.

Abstract:
In general, a seismic load acting on a structure is considered to potentially cause unstable gross plastic deformation that is called as plastic collapse, because the seismic load induce an inertia force on the structure which may act as an external force onto the structure. The past researches by the authors to clarify the characteristic of seismic loads found that the way of the seismic response on the structure is driven by the correlation between the seismic loading and the natural frequency of the structure while only the dynamic loads are acting. On the other hand, existence of relativel

Full text
Abstract:
Currently, AASHTOWare PMED does not contain a framework to compute distresses for loading scenarios like truck platoons. Truck platoons reduce fuel consumption and improve safety while increasing pavement damage because of a reduction in wander and rest period. The important parameters of truck platoons are wander, rest period, and penetration level. Unlike wander, the effect of reduced rest period on permanent deformation and platoon penetration level are not well documented. Rest period (i.e., truck spacing) is a critical parameter in platoons that can be controlled to reduce damage or to im

Abstract:
Rapid assessment of low-volume road surfaces remains a challenge when attempting to forecast allowable vehicle crossings. Variations in soil type, compaction effort, and moisture content of the soil can greatly affect trafficability, and predictive equations for soil deformation under vehicle loads often have reduced reliability for low-strength materials. Portable tools to characterize soil stiffness and corresponding relationships to load-induced deformation are needed. In this effort, researchers performed comparative testing of multiple rapid assessment tools as potential devices for givin

Abstract:
To verify the safety application and use of Cr-Mo steel for the high-pressure hydrogen equipment, tensile, fatigue, and crack growth tests of JIS-G4105-1979 SCM435 and 440 steel under 45MPa high-pressure hydrogen at room temperature were conducted. There were no significant differences in tensile deformation behaviors between the air environment and 45MPa hydrogen until the maximum load point. However, the hydrogen tested specimen broke with less ductility accompanied by many surface crack on the specimen surface which is caused by the specimen machining. The scatter of ductility was observed

Full text
Abstract:
Truck platoons are expected to improve safety and reduce fuel consumption. However, their use is projected to accelerate pavement damage due to channelized-load application (lack of wander) and potentially reduced duration between truck-loading applications (reduced rest period). The effect of wander on pavement damage is well documented, while relatively few studies are available on the effect of rest period on pavement permanent deformation. Therefore, the main objective of this study was to quantify the impact of rest period theoretically, using a numerical method, and experimentally, using

Abstract:
For robust pavement design, accurate damage computation is essential, especially for loading scenarios such as truck platoons. Studies have developed a framework to compute pavement distresses as function of lateral position, spacing, and market-penetration level of truck platoons. The established framework uses a robust 3D pavement model, along with the AASHTOWare Mechanistic–Empirical Pavement Design Guidelines (MEPDG) transfer functions to compute pavement distresses. However, transfer functions include high variability and lack physical significance. Therefore, as an improvement to effecti

Abstract:
This report describes a research project for evaluating the applicability of the widely accepted 80 percent criterion for elongation of ground anchors to anchors with unbonded lengths exceeding 100 feet. This issue is driven by several recent projects involving ground anchors for landslide stabilization in which a significant percentage of the anchors did not meet the criterion that requires measured elongation during proof load testing of at least 80 percent of the theoretical elastic elongation. The projects involved anchor unbonded lengths in the range of 85 to 220 feet, which is outside th

Abstract:
The overall goal of this project was to investigate the role of torsional deformations and major axis bending deformations in lateral instability of long girders, specifically their effect on the theoretical buckling load. A closed-form solution showed that the torsional deformations do indeed reduce the buckling load below the value predicted by the present lateral-roll buckling model by an amount that can be captured with a “knockdown factor.” A numerical tool (ROLLBUCK) was also developed and checked against the closed-form solution for configurations that the latter could address.

Abstract:
Researchers have been studying wide-base tires for over two decades, but no evidence has been provided regarding the net benefit of this tire technology. In this study, a comprehensive approach is used to compare new-generation wide-base tires (NG-WBT) with the dual-tire assembly (DTA). Numerical modeling, prediction methods, experimental measurements, and environmental impact assessment were combined to provide recommendations about the use of NG-WBT. A finite element approach, considering variables usually omitted in the conventional analysis of flexible pavement was utilized for modeling. F
