Workshop for Finite Element Methods for Composites Held in London, United Kingdom on 5-6 September 1991

Abstract

The objective of this Workshop was to consider the current position of applying the finite element method to applications involving composite materials. It was expected that issues needing attention would be identified. Some technical conclusions were as follows: (1) The actual material must be modelled; (2) Properties must be appropriate to the scale of the analysis; (3) The system must allow for correct orientation of the material; (4) It should be possible to represent (ply) discontinuities; (5) It should be possible to incorporate through-thickness modelling; (6) Specific formulation is needed to allow for iteration; (7) It should be possible to include material and geometric non-linearity; (8) Include relevant critical mechanical properties; (9) System must be able to identify failure mode(s); and (10) Consider using spreadsheets to interface input data with FE system users need more, and better, communication with software vendors establish a system (benchmarks) for verifying results.
