Finite element method analysis of fibre-metal laminates considering different approaches to material model

Abstract

In this work, different approaches to fibre-metal laminates modelling are presented. Micromechanical, mesomechanical and macromechanical models are discussed. The application of these approaches for exemplary fibre-metal laminate made of aluminium and epoxy resin/glass fibre layers are shown. The classical laminate theory was used to obtain engineering constants for the macroscopic solid model and Puck criterion to obtain material data about epoxy resin/glass fibre layer. Various simulations using different simulation techniques were carried out in Simulia ABAQUS environment and results were compared with experimental data found in the literature. In conclusions, described approaches from the viewpoint of numerical simulation and experiment were evaluate. Research proves that mesoscopic (with distinguished layers of material) approach along with solid model gives the best results.
