DOI: 10.1007/s12289-017-1347-6
Abstract: Constitutive models based on non-associated flow rule enable the accurate description of complex anisotropy phenomena by using distinct, but relatively simple, mathematical description for yield function and plastic potential. The computational complexity of stress integration… read more here.
