compute_CS

compute_CS(e_at_int_points, X_at_nodes, U_at_nodes, S_at_int_points, element_type, method)

Compute the configurational stresses for num_elem elements of the given element type. This element type has n nodes and ips integration points. 2d elements have d=2 dimensions. 3d elements have d=3 dimensions.

• Supported methods are:

  • “mbf” conforce_gen.expressions.eval_CS_mbf()

  • “dbf” conforce_gen.expressions.eval_CS_dbf()

Parameters:

• e_at_int_points – Array of shape (num_elem, ips) containing the Helmholtz free energy densities at ips integration points for num_elem elements.

• X_at_nodes – Array of shape (num_elem, n, d) containing the coordinates at n nodes of num_elem elements.

• U_at_nodes – Array of shape (num_elem, n, d) containing the displacements at n nodes of num_elem elements.

• S_at_int_points – Array of shape (num_elem, ips, d, d) containing the symmetric stress tensors at ips integration points for num_elem elements.

• element_type – str, name of an element type

• method – str, name of the method for the computation of the configurational stress.

Returns:

CS_at_int_points: Array of shape (num_elem, ips, d, d) containing the configurational stresses evaluated on ips integration points for num_elem element.
