14. L modeling

14.1. Characteristics of modeling

Isotropic multilayer plate (5 layers in thickness). DST triangular shell element.

The plate model associated with modeling \(K\) is rotated 20 degrees according to the alpha nautical angle and 30 degrees according to beta. The cell numbering is the same as in modeling \(K\).

Boundary conditions:
