Research project: In-situ calibration of cohesive zone models for composite damage

Currently Active: 
Yes

With an aim to reduce the cost and time involved in designing new composite components, many models have been developed that characterise and predict damage in carbon fibre-epoxy composites as a guide to various strength and lifing parameters.  These models are predominantly empirically based or fitted to the test samples from which the data sets are produced and cannot, therefore, be truly predictive since alternative material constructions would require alternative fitting functions.

Project Overview

This project aims to develop a 3D model based on a micro-mechanical approach, using high resolution computed tomography (CT) to obtain 3D images of damage in experiment samples for comparison and calibration.  Digital image correlation (DIC) will be used to produce a 3D strain map that can be used to obtain information of residual stresses induced by manufacture and loading.
