The wide application of advanced high strength steels with specific in the automotive industry can significantly reduce energy consumption and contribute to carbon neutrality. Accurate prediction ductile fracture behavior under complex stress states is great significance for its automobile industry. In this study, QP980 states, covering shear, uniaxial tension, plane strain investigated by cond...

The finite element analysis is adopted in this primary study. Using the Tsai-Wu criterion and delamination criterion, the stacking sequence [45/04/−454/904]s is the final optimal design for the wheelchair frame. On the contrary, the uni-directional laminates, i.e. [9013]s, [4513]s and [−4513]s, are bad designs due to the higher failure indexes. Keywords—Wheelchair frame, stacking sequence, fail...

1024x768 normal 0 false false false en-us x-none fa background : heart failure is a common health problem with poor prognosis. the gold standard for diagnosis is echocardiography but it is not always reachable, especially in emergency conditions. nt-pro-brain natriuretic peptide (nt-probnp) is a novel indicator for the diagnosis of heart failure and is being used in routine tests in emergency r...

Several different fuel failure criteria have been used in previously NRC-sponsored SFP accident studies. Benjamin, et. al. used the onset of runaway fuel clad oxidation as the fuel failure criterion in NUREG/CR-0649 [Ref. 1]. This criterion was criticized because clad rupture can occur at a relatively low temperature causing a gap release. The consequences of gap release can be significant if t...
