摘要
从弹性理论出发 ,推导出了变系数弹性模型。利用此模型 ,计算了二维沙堆式样里的应力分布 ,得到了试样底面应力分布曲线有低陷的结论 ,并用不同方法验证了模型的稳定性与准确性。
We deduce the Variational coeffcient elastic model from theory of elasticity,and calculate the stress distributions in a sandpile in two dimensions using this model.The result shows a dip in the curve of the stress distibutions.The conclusions of different methods confirm the stability and accuracy of the model.
