an internal length parameter was included in the yield function to describe the interactions and interplay among microstructures were used to calculate the local temperature rise in the deformed ASB... rise T1 at pre-peak and the temperature rise Tm(y) at post-peak due to the microstructural effect[12]: where β is the work to heat conversion factor, cp is the heat capacity and ρ......
Numerical analysis of temperature rise within 70 MPa composite hydrogen vehicle cylinder during fast refuelingWANG Liang(王亮)1, ZHENG Chuan-xiang(郑传祥)1, LI Rong(李蓉)1, CHEN Bing-bing(陈冰冰)2, WEI Zong... considered turbulence, real gas effect and solid heat transfer issues. Through the numerical analysis method, the temperature distributions of the gas within the solid walls were revealed; adiabatic filling......
, deformation, temperature rise and damage variable, cannot be accurately predicted. After introducing gradient-dependent plasticity (a special case of the nonlocal theory) into the JOHNSON- COOK (J-C) model, WANG[7-11] investigated the distribution of the local strain, deformation and the temperature rise in ASBs of Ti-6Al-4V alloy and steels, the phase transformation condition and the thickness......

fracture modes exist in transition from adiabatic shear banding to fracture. Temperature rise in ASBs causes the generation of voids and then the voids are transformed into elongated dimples that exhibit... for the reorientation of grain boundary. Under dynamic loading condition, the adiabatic temperature rising during the course of dynamic loading can be calculated as: ......
