Abstract With the development of rail transit industry, more attention has been paid to passive safety vehicles. Structural damage is one main failure behaviors in a vehicle collision, but it little past research. In this paper, quasi-static fracture experiments SUS301L-MT under different stress states were carried out. The mechanical properties material studied, and corresponding finite elemen...

due to the probabilistic nature and uncertainties of structural parameters, reliability-based optimization will enable engineers to account for the safety of the structures and allow for its decision making applicability. thus, reliability-based design will substitute deterministic rules of codes of practice. space structures are of those types that have an exceedingly high range of applicabili...

safety and failure in gas pipelines are very important in gas and petroleum industry. for this reason, it is important to study the effect of different parameters in order to reach the maximum safety in design and application. in this paper, a three dimensional finite element analysis is carried out to study the effect of crack length, crack depth, crack position, internal pressure and pipe thi...

conclusions abnormal transaminases and uric acid levels are seen in ahf patients. increased ast levels may be a predictor of the need for inotrope during hospital course in these patients. patients and methods a total of 100 patients (aged 16 - 90 years, 60% men) admitted with ahf were enrolled. lfts and uric acid levels were assessed on first day and before discharge, and patients were followe...
