Sažetak
In this work, building on the earlier work briefly reviewed above, a rate-dependent mixed- mode interface element is implemented within a multi-layer beam environment consisting of two- or three-nodded beam finite elements. The presented model is verified against experimental results for mode I delamination (DCB test) and computationally more expensive models which use plane-strain 2D finite elements with significantly higher number of degrees of freedom. Special attention is dedicated to the choice of optimum solution procedure for the non-linear problem and reducing the computation time.
