摘要
双模量矩形板在外载荷作用下,会形成各向同性的拉伸区和压缩区,把双模量矩形板看成两种各向同性材料组成的层合板,采用弹性力学理论建立了双模量矩形板在外载荷作用下的静力平衡方程,利用静力平衡方程确定了双模量矩形板的中性面位置,推导出了双模量矩形板的弯曲变形微分方程,并讨论分析了双模量对矩形变曲变形的影响.
Bimodulous rectangular plate could form isotropic compression and tensile area under external loads. Bimodulous rectangular plate was regarded as laminated plate composed of two kind of otropic material. Static equilibrium equation of bimodulous rectangular plate under the condition of external loads was established by using elastic mechanics theory. The location of neutral plane in bimodulous rectangular plate was determined by the utilization of static equilibrium equation. The bending deformation differential equtions of bimodulous rectangular plate was derived, and the effect of bimodulous on the bending deformation of rectangular plate was discussed and analyzed.
