Abstract
AbstractThis contribution presents a mixed C0 continuous finite element approach for gradient enriched formulations. The approach is based on a split of the Lagrange multiplier into a gradient and a rotational part, through which a decoupled set of variational equations is obtained. Application to numerical examples in the finite strain gradient elasticity framework unveils the reduced computational effort due to the decoupled character of the global system of equations such as the ability to avoid stress localization.
