fedoo.constitutivelaw.ShellLaminate

class ShellLaminate(list_mat, list_thickness, k=1, name='', *, output_points=None, n_points=3)

Elastic layers ordered bottom to top along the local shell normal.

In-plane strain is epsilon0 - z*kappa. The coupling blocks are therefore -B, where B = integral(z*C) through the thickness. Generalized moments are -integral(z*sigma), conjugate to the existing curvature convention.
