Implementation, identification and validation of an elasto-plastic-damage model for the finite element simulation of structural bonded joints
Source abstract
Abstract
Abstract This paper focuses on the quasi-static three-dimensional finite element (FE) analysis of structural bonded joints using an advanced material constitutive model. This model predicts multi-axial pressure-dependent plasticity as well as damage and failure in confined adhesive layers. The formulation of plasticity, which considers the influence of hydrostatic pressure, is recalled and the implementation of damage and fracture, using cohesive zone (CZ) modelling is detailed. The identification of material constitutive parameters is addressed using butt-bonded hollow cylinders loaded under different load paths, double cantilever beams (DCB) and end notched flexure specimens (ENF). The set of material parameters identified is crossed-checked using modified Arcan specimens and finally validated by the FE analysis of an industrial benchmark. The methodology developed combines results accuracy and computational efficiency and is well adapted to the numerical simulations of large adhesively bonded industrial structures.
