摘要
论述了将轴对称问题自三维空间转化为轴平面内问题的过程并编制出相应的受拉压和扭转的线性和二次边界元程序。通过4个算例将边界元计算结果同解析解、有限元解或用其他方法所得结果进行比较表明,采用二次边界元可获得极好的计算精度。
A transformation procedure of axisymmetrical elasticity problems from space 3D to axial plane is described and a corresponding program with linear and quadratic boundary elements in tension compression and torsion is developed. 4 test examples are given and the results calculated by BEM are compared with analytical solutions, finite element solutions and the ones by other methods. The comparisons show that the quadratic boundary elements provide excellent accuracy.
