摘要
利用正弦级数和最小势能原理,解答了无拉力Winkler地基上梁的脱离问题.所采用的方法具有计算简单,收敛速度快的特点.计算结果表明,Winkler地基上梁弯曲时的线性解与非线性解有较明显的差异.
In this paper, the bending problem of unbonded contact of beams on tensionless winkler foundations is investigated by sine series and principle of minimum potential energy. The distinguishing features of the method used are their being simpler in computation and faster in convergence. The numerical results show that, there are obvious differences in the solutions of linear and nonlinear problems.
