A post-processor approach for stress analysis of woven textile composites

In this study, macro-elements have been extended for the post-processing of detailed stresses of woven-textile composites. A symmetric plain-weave unit-cell configuration was analyzed to evaluate the performance of the post-processors. The stress results by macro-element post-processors were compared to those by conventional analyses. Results indicated that the post-processors were able to predict detailed stresses to a reasonable level of accuracy for woven-textile composites. The usefulness of the post-processor was demonstrated for a 5-harness satin-weave configuration.
