Stretching-twisting coupling effect of antisymmetric laminate

摘要

With stretching-twisting coupling effect, antisymmetric laminate plate usually twists when loaded by in-plane forces. In this paper, the twisting deformation of arbitrary antisymmetric laminate loaded by tensile strength is analyzed The optimum lamination layup is proposed, by which the plate has small thermal deformation during curing process, but reserves sufficient stretching-twisting coupling effect under tensile loading. Based on the analysis, three types of tensile specimens including the optimum layup one were manufactured. Initial experiments were performed. The experimental results agree with the analytical predictions quite well.
