A numerical method for a class of hemivariational inequalities (Q1804485)

We propose a method for the decomposition of the hemivariational inequality into a finite number of variational inequalities (monotone problems). The method is based on the decomposition of the contingent cone of the superpotential into convex constituents and gives rise to a very effective and reliable numerical algorithm for large scale hemivariational inequalities. Numerical results on the delamination of composites and discussion of the numerical aspects illustrates the theory.
