压杆非保守稳定问题的边界区域单元法

Border Zone Element Method for Solving the Stability of Compression Member Subjected to Non-Conservative Forces

本文利用作者在文[1]中提出的边界区域单元法,求解非保守力作用下的压杆稳定问题,建立了求解Beck杆Leipholz杆临界荷载的统一计算程序,并给出了不同边界条件下的临界荷载。

For solving the stability of compression member subjected to non-conservative forces,this paper makes use of border zone element method presented by the author in literature.An unified program is formed for computing critical load of Beck bar and Leipholz bar,and the critical lands usder boundary condition are also given.
