摘要

Evaluation of interlaminar stresses in composites plays a crucial role to ensure structural integrity. It is quite often to have composites consisting of very thin anisotropic multilayers. Traditional domain modeling of ultra-thin multilayers usually requires a tremendous amount of refined elements that might cause computation overloading. This article proposes an efficient computational methodology for evaluation of two-dimensional interlaminar stresses in thin anisotropic composites subjected to inertial loads. This analysis is by the regularized boundary integral equation (BIE) that employs only very coarse meshes. In the present work, the directly transformed boundary integral equation is regularized using the scheme of integration by parts and analytical integration. By the proposed approach, modeling of very thin layered composites can be performed simply by very coarse mesh. The obvious advantage of the present method over conventional methods is the much less modeling efforts that are required for analyzing very thin multi-layered composites. For verifications, a few benchmark examples are presented in the end.
