【摘要】 用边界元法对具有中心圆孔的纤维增强复合材料对称角铺设层合板的轴压稳定性进行了研究，分析了铺设角和孔径－板宽比对具有中心圆孔复合材料层合板在轴压荷载作用下的临界荷载值的影响。同有限元法比较，结果表明，应用边界元法节约了计算机时，而且计算精度较高。更多还原

【Abstract】 By the boundary element method, this paper studies the axial compression stability of centrally-perforated fiber-reinforced compcsite laminates laid at symmetric angles, analyzing the influence of the laid angle and the ratio of hole diameter to plate width on the critical loads . As compared with the finite elenent method, the boundary element method is characterized by time - saving and high computation accuracy.更多还原
