Numerical approximation for algorithmic tangent moduli for nonlinear viscoelastic model with CSDA method
Abstract This work revisits the notion of complex step derivative approximation (CSDA) and presents its use in constitutive model of a class of nonlinear viscoelastic materials. The effectiveness of a CSDA is evaluated by putting it through a series of straightforward examples. After that, the idea...
