Viscoplastic deformation is characterized by a combined system of balance and evolution equations. The application of the Finite Element Method results in a Differential‐Algebraic Equation (DAE) in time. The paper summarizes the most important points of the mathematical model and presents a benchmark problem for numerical comparisons. As computational example, the BDF‐2 method with stepsize control is applied.
