摘要
采用考虑钢材失效的双线性混合强化本构关系能够简洁有效地考虑考虑材料的强化、包辛格效应和失效,这在钢结构大变形的数值模拟中是必要的。采用显式有限元软件LS-DYNA软件验证了这一本构关系在钢结构大变形问题中的适用性,验证算例为梁柱节点拟静力试验和抗弯钢框架静力试验。
Bilinear constitutive model considering material failure includes material strengthening, bauschinger effect and failure, which is necessary in numerical simulation of large formation of steel structure. The explicit element software LS-DYNA was taken to verify the application of the constitutive model through simulations of quasi-static tests of beam-column joint and static test of moment steel frame.
