- stiffness_tensor_components_hexagonal_crystal(stiffness_tensor)[source]#
Computes 5 independent elastic stiff components of a hexagonal crystal from the whole stiffness tensor
For a hexagonal structure the 5 components are c11, c33, c44, c12, c13
- Parameters:
stiffness_tensor – The full(3,3,3,3) elastic stiffness tensor
- Returns:
A (5,) ndarray containing (c11, c33, c44, c12, c13)
