摘要

本文研究了单次分层结构的屈曲问题。结构由层压板和功能梯度材料（FGM）制成。这项工作的第一部分致力于借助于各种函数不等式来表述接触问题。然后讨论了计算模型。最后讨论了球壳和压缩矩形板屈曲的两个特殊问题。研究结果表明，FGM结构的非对称结构可以降低分层结构的屈曲载荷。

Computational and Variational Formulations of Unilateral Problems for Structures Made of Composite Materials (Laminates, Functionally Graded Materials)

In the present paper buckling problems of constructions with a single delamination are conducted. Structures are made of laminates and functionally graded materials (FGM). The first part of the work is devoted to the formulation of contact problems with the aid of various functional inequalities. Then computational models are discussed. Finally two particular problems dealing with buckling of spherical shells and compressed rectangular plates. The results demonstrate that the unsymmetric configurations of FGM structures leads to the reduction of buckling loads for structures with delamination.

期刊介绍： WSEAS Transactions on Applied and Theoretical Mechanics publishes original research papers relating to computational and experimental mechanics. We aim to bring important work to a wide international audience and therefore only publish papers of exceptional scientific value that advance our understanding of these particular areas. The research presented must transcend the limits of case studies, while both experimental and theoretical studies are accepted. It is a multi-disciplinary journal and therefore its content mirrors the diverse interests and approaches of scholars involved with fluid-structure interaction, impact and multibody dynamics, nonlinear dynamics, structural dynamics and related areas. We also welcome scholarly contributions from officials with government agencies, international agencies, and non-governmental organizations.
