ANSYS中常用shell 181来模拟复合材料层合板,但是ANSYS LS-DYNA只可选用16X系列单元,那么在ANSYS LS-DYNA中该如何建立复合材料层合板模型呢?
LS-DYNA user manual:
ICOMP option of the *section_shell, card 1: Flag for orthotropic/anisotropic layered composite material model. This option applies to material types 22, 23, 33, 34, 36,40,41-50, 54-56, 58,59, 103,116,and 194.
EQ.1: a material angle in degrees is defined for each through thickness integration point. Thus, each layer has one integration point.
