Decohesion finite element with enriched basis functions for delamination
Source abstract
Abstract
In order to address the stringent mesh size requirement of the cohesive element, currently 0.5 mm or less, the mixed-mode interface finite element is enriched with the analytical solution of an idealized beam on elastic foundation. Both the interface and the solid continuum elements are enriched; the partition of unity (PU) method is utilized to obtain the enhanced interpolation, implemented with two user elements (UEL) in the commercial package ABAQUS/Standard. The new formulation yields predictions in excellent agreement with theoretical and experimental results for a typical mode I delamination benchmark, with elements 5 mm in size.
