Mechanical Behaviour Analysis of Advanced Materials by Multi-Scale Finite Element Modelling
Abstract: Finite element modelling is a widely used tool to analyse and predict the mechanical behaviour of structures. For advanced materials which are heterogeneous and orthotropic, performing multiple scale simulations are significant to fully understand the mechanical characteristics of these materials. In this presentation, three different studies that involves finite element analysis in different scales with such advanced materials are presented. In the first part, the fatigue crack propagation analysis of functionally graded materials is presented. In the second part, the mechanical behaviour of a textile product called nonwovens is analysed including some tests such as creep and orientation distribution determination. In the third part, a micro-scale computational analysis is performed to assess the stress concentrations in a new composite type: steel fibre reinforced composites.
