摘要 采用与获得压缩模量类似的假设，为粘合到刚性端板的软弹性材料块的平面应变旋转模量建立了一个简单的关系。当一个板相对于另一平面围绕沿其宽度中心的轴线旋转时，就会产生变形。对于泊松比为 0.333、0.483 87 和 0.499 83 的材料以及宽厚比为 0.25 至 64 的块体，近似理论解与有限元分析数据非常吻合。
Abstract Making assumptions similar to these used to obtain compression moduli, a simple relation is developed for the plane strain rotation moduli for blocks of soft elastic material bonded to rigid end plates. The deformation arises when one plate rotates relative to the other plane about an axis along the centre of its width. The approximate theoretical solution compares well with finite-element analysis data for materials with Poisson's ratios of 0.333, 0.483 87 and 0.499 83 and blocks having width-to-thickness ratios between 0.25 and 64.
