compute_stiffness

module opensg.core.shell

opensg.core.shell.compute_stiffness(ABD, mesh, subdomains, l_submesh, r_submesh)

Compute stiffness matrices for shell segments.

Parameters:

• ABD (numpy.ndarray) – ABD matrix

• mesh (dolfinx.mesh.Mesh) – Mesh object

• subdomains (dict) – Subdomain data

• l_submesh (dict) – Left submesh data

• r_submesh (dict) – Right submesh data

Returns:

tuple – segment_timo_stiffness, segment_eb_stiffness, l_timo_stiffness, r_timo_stiffness
