Abstract In aerospace engineering, design and optimization of mechanical structures are usually performed with respect to elastic limit. Besides causing insufficient use the material, such concept fails meet ever growing needs light weight design. To remedy this problem, in present study, a shakedown theory based numerical approach for performing parametric is presented. Within approach, streng...

This research investigates the static and cyclic characteristics of recycled glass (RG) as a supplementary material with concrete aggregate (RCA) in rail track capping layer. RG was blended by-weight RCA 10% increments up to 50% content. A performance-based laboratory testing scheme designed according field loading conditions layers tracks. Basic geotechnical properties + blends were evaluated ...

Surface fatigue wear widely exists, and it occurs as long a sufficient number of loading–unloading cycles are applied. Slowing down surface requires understanding the evolution damage in surface. Real surfaces composed many asperities; therefore, is important to study single asperity. A finite element model an asperity subjected cyclic elastic–plastic normal loading was developed under friction...

OBJECTIVE This work seeks to complement and extend prior work by using a multidisciplinary approach to explain electronic medical records (EMR) system use and consequent performance (here, patient satisfaction) among physicians during early stages of the implementation of an EMR. DESIGN This was a quantitative study, with data obtained from three distinct sources: individual-level and social-...

Creep-cyclic plasticity and creep-fatigue damage interaction of a welded flange are studied considering both the thermo-mechanical load welding residual stress (WRS). The presence WRS was found to have minimal effect on shakedown ratcheting curves, though distribution changes considerably in WRS. is predominant for initial cycles after which it relaxes so that at steady state creep-cyclic respo...

Tóm tắt
 Trong bài báo này trình bày thuật giải cho toán phân tích kết cấu 2D sử dụng công thức động học giản yếu. Phần tử trơn trên cạnh (ES-FEM) hợp với tối ưu nón bậc 2 sẽ được trong thích nghi yếu này. Nghiên cứu thấy phương pháp đề xuất, mặc dù tính chính xác tăng lên đáng kể nhưng số biến của bài toán tối không nhiều, đảm bảo hiệu quả về chi phí toán.
