复合材料层合板屈曲行为的一般场函数半解析法
A semi-analytical general field function methodology for the buckling of laminated composite plates
摘要
Abstract
In this paper,based on the principle of energy variation,a general field function method with a universal deformation mode is proposed,and the buckling behavior of composite double-layer plates is studied.The displacement field function is composed of the basis function.The weight coefficient constructed by the elementary function,and the corresponding linear equations can be established considering that the boundary constraints also meet the conditions of the field function.The weight coefficients can be obtained from the linear combination of the basic solution of the linear equations.This method effectively solves the problem that the selection of the field function of the traditional energy method is limited by the type of boundary constraints,and has a high degree of freedom and accuracy,which provides a basis for practical engineering applications.关键词
