This minisymposium deals with the computational modeling of gradient extended theories. Classical or conventional theories are often insufficient to model material behavior correctly. In case of classical plasticity, gradient extended approaches have been developed in order to capture size dependent effects or shear bands, for example. This is realized by including higher order stresses or higher order derivatives of internal variables in the yield criterion, for example.
In order to overcome the drawback of classical theories of plasticity, extended theories Regarding computational methods solving the resulting highly coupled (and in case of large deformations highly nonlinear) several different approaches exist. In the minisymposium, we aim at contributions introducing the current directions of research and discussing the advantages and shortcomings of the computational methods. Problems from material science, biomechanics, mechanical engineering are to be dealt with.
