| 摘 要： | 拉压弹性模量不同的圆板在均布外载荷作用下,会形成拉压弹性模量不相同的拉伸区和压缩区,把拉压弹性模量不同的圆板看成两种材料组成的层合板,采用弹性力学理论建立了拉压模量不同圆板在均布外载荷作用下的静力平衡方程,利用静力平衡方程确定了拉压弹性模量不同圆板的中性面位置.在此基础上,建立了拉压弹性模量不同圆板的非线性弯曲微分方程...

| Abstract: | A bimodulus circular plate could form a compression and tensile area under external uniform loads.And it was regarded as a laminated plate composited of two kinds of materials.The static equilibrium equation of a bimodulus circular plate under external uniform loads was established using elasticity theory.Then the location of a neutral plane was determined by static equilibrium equation.The nonlinear bending deformation differential equation of a bimodulus circular plate was derived,and the relation between... |
