本文以一简单的胶粘两块板的模型说明内聚力单元在ABAQUS和LS-DYNA软件中的应用。 ABAQUS采用的隐式计算,在显式计算中的设置与隐式计算的设置相同,LS-DYNA采用的显式计算,由于给的时间较短,可以看出板有明显的抖动,仅供交流学习,感兴趣的可以下载后边的.inp和.k文件...
Fix no *ELEMENT_SHELL output to dynain file if the NOTHICKNESS option is present in *INTERFACE_SPRINGBACK_LSDYNA_NOTHICKNESS. Write complete history variables to dynain file for 2D solids using *MAT_NULL and equation-of-state. Fix incorrect transformation when using *DEFINE_TRANSFORMATION with opt...

Currently only useful when linking with MPP LS-DYNA for modeling of multiscale spotwelds. (*BOUNDARY_COUPLED, *DEFINE_SPOTWELD_MULTISCALE, *INCLUDE_MULTISCALE_SPOTWELD) Add check in MPP of installed memory on system and requested memory. If requested memory exceeds the real memory, the job ...
The cohesive element fails, when the ultimate mixed mode displacement δF is reached. For the calculation of δF, two alternative formulations are currently implemented into LS-DYNA: • The Power Law (values of XMU > 0) ( ) XMU XMU XMU F GIIC ET GIC EN 1 2 0 2 1 2 − ...

Traditional Ansys LS-DYNA® approaches, such as usingPART_COMPOSITEorMAT_LAMINATED_GLASS, are limited. These methods, particularly when using element erosion to simulate cracking, tend to exaggerate the loss of stiffness and create a non-physical loss of mass. While methods to mitigate these effec...
