A 3D Progressive Failure Model for predicting pseudo-ductility in hybrid unidirectional composite materials under fibre tensile loading

A 3D Progressive Failure Model for predicting pseudo-ductility in hybrid unidirectional composite materials under fibre tensile loading

The contribution A 3D Progressive Failure Model for predicting pseudo-ductility in hybrid unidirectional composite materials under fibre tensile loading  by J.M. Guerrero et al. has been published in the journal Composites: Part A. A 3D failure model is proposed that includes progressive damage and pseudo-ductile behaviour in unidirectional hybrid composites. It is a quite convenient tool that gives good results with less computational effort than micro-mechanical finite element models.

Highlights

    A new failure model for hybrid unidirectional composite materials under fibre tensile loading is presented

  • A representative volume element with a random distribution of fibres with their own radius is considered
  • Complete stress distributions around breaks are obtained by means of damage and stress concentration
  • The model exhibits good agreement with hybrids and non-hybrid composites
  • The aim of the model is to simulate the tensile response with a reduced computational effort
