【摘要】 结合矩形板的几何特征,采用Ritz-有限条法分析计算了弹性板在侧向载荷作用下的面内应力和板的屈曲。本方法可大大地降低特征值矩阵阶数,极大地节省计算机机时,使以往只能在大、中型计算机上进行的计算在微机上进行。更多还原

【Abstract】 Considering the geometric features of rectangular plate and using the Ritzfinite strip method, this paper analyses and calculates the plane stresses and buckling of elastic plate under sideway load. This method makes the dimensions of eigenvalue matrix lower and greatly saves the total computing time. The buckling problems which had to be calculated on large compters, now, could be calculated on personal computer.更多还原
