摘要

摘要: 对位于弹性基底上的、具有可压缩非线性芯子的3层弹塑性杆的弯曲问题进行了研究．研究分析了由2个受力层和1个芯子层组成的3层构件的力学响应．解决了位于弹性基底上的3层杆弯曲的复杂问题．对所给出的弹性解法进行了收敛性检验，以保证该弹性解是可以接受的．计算结果表明，材料的塑性和物理非线性对位于弹性基底上的夹层结构杆的变形影响很大．

Abstract: The problem about bending of the three-layer elastic-plastic rod located on the elastic base, with a compressibly physical nonlinear core, was studied. The mechanical response of the designed three-layer elements consisting of two bearing layers and a core was examined. The complicated problem about curving of the three-layer rod located on the elastic base was solved. Convergence of the proposed method of elastic solutions was examined to convince that the solution is acceptable. The calculated results indicate that the plasticity and physical nonlinearity of materials have a great influence on the deformation of the sandwich rod on the elastic basis.
