Modelling mixed-mode rate-dependent delamination in layered structures using geometrically nonlinear beam finite elements

Delamination is one of the one most important problems for layered structures, which are widely used in industry (e.g. composite laminates) and also often present in nature (e.g. layered biological tissue). In this work delamination is studied using cohesive-zone models (CZMs) where a discontinuous displacement field and a non-linear traction-separation law on the considered interface are assumed.
