Remarks on a primal‐dual interior point algorithm for single crystal plasticity

In the field of single crystal plasticity, different algorithms exist for solution constitutive equations. They can be grouped into rate independent and dependent approaches, where both classes are governed by inherent shortcomings, as discussed in, e.g., [3]. This contribution outlines an algorithmic formulation plasticity at small strains case relying on infeasible primal-dual interior point method, which has been presented in [5]. It is able to bypass several issues known algorithms. Besides a brief overview continuum mechanical framework, aspects formulations related Karush-Kuhn-Tucker (KKT) conditions discussed.
