Abstract

Computer modelling of 3-D woven composites J.A. Hewitt, R.B. Clarke Engineering Composites Research Centre, University of Ulster at Jordanstown, Shore Road, Co. ABSTRACT Modelling of 3-D woven composites provides a means of correlation of experimental and theoretical values of elastic constants of the multitude of different possible weave geometries. Finite element modelling for stress-strain analysis of a weave geometry is complex; hence a weave model which will aid finite element meshing will significantly reduce computation time and effort. A computer model of a 3-D weave has been developed using a 'building blocks' approach. In the model, a number of blocks have been devised which fit together to generate a range of 3-D weaves. Use of the model is illustrated by producing one particular 3-D geometry, that of a T section. The web of the T contains four warp layers and the flanges of the T are formed by weaving two of the warp layers separately fo
