3秒自动关闭窗口abaqus求解线性(非线性)屈曲,如何得到屈曲载荷
用非线性屈曲分析,载荷是通过载荷步一步步加上去的,载荷是由载荷因子乘以预加载荷得到的.如果加载的是压力,那就乘以面积,然后在乘以屈曲载荷.具体的屈曲载荷是通过载荷-位移的拐点来获得.具体一点的屈曲载荷可以在 step历史输出选择力的输出,然后在选择某一点,就可以了.如果是单方向加载的话,可以直接用支反力求和后与位移作位移载荷曲线,曲线上线性段的最大载荷应该就是屈曲载荷了~

Modeling ductile dynamic fracture with ABAQUS/explicit
Description:
This paper illustrates the use of advanced constitutive models in ABAQUS/Explicit together with highly focused finite element meshes to simulate the propagation of a fracture in a ductile medium. A double edge-cracked specimen under far field dynamic tensile loading is analyzed, and shows both rectilinear motion or unstable oscillatory motion of the crack depending on the material property constraints. Results are also presented for a simulation of ASTM`s standard fracture test E399. Comparisons of ABAQUS/Explicit results with experiments or other analytical/numerical results are made.
