摘要
针对含矩形孔的复合材料板,根据非均质各向异性弹性理论,建立了基于准确的边界条件的边界积分方程,得到开口结构的应力分布,给出了含矩形孔复合材料板的精确解析解.按照所建立的数学模型对不同的矩形孔在偏轴荷载作用下对孔边应力集中系数的影响进行探讨.
Based on the nonhomogeneous anisotropic elastic theory, boundary integral equations of orthotropic plate with rectangle hole are developed on accurate boundary conditions. Stress distribution of opening structure is obtained, and accurate analytical solutions of composite materials plate with rectangle hole are given. The influence of off-axis loads on hole-edge stress concentration factors are discussed on the basis of the mathematic model.
