2. Assignment of characteristics

For these plate or shell elements, it is necessary to assign geometric characteristics that are complementary to the mesh data. These data are defined with the AFFE_CARA_ELEM command associated with the following factor keyword:

COQUE

Allows you to define and affect the meshes, the thickness, the shear coefficient, the eccentricity,…

For the study of structures comprising multilayer materials it is necessary to assign the characteristics of each of the layers (thickness, type of material) and their stacking (orientation of the fibers). The definition of this data is done with the DEFI_COMPOSITE command.
