| 摘 要： | 材料力学里对平面弯曲梁横截面上的切应力分布进行了假设,利用假设条件下推导出来的公式来求解截面上的切应力值。但是这些假设并没有进行验证,其正确性还有待实践证明。文中利用有限元通用分析软件—Ansys软件,对平面弯曲梁的弯曲变形进行了数值模拟,验证了材料力学关于切应力分布规律的假设。

| Abstract: | In mechanics of materials, there is a hypothesis concerning the distribution of the shear stress on the cross section of bending beam and how to work out the value of shear stress using the formula deduced form the hypothesis. However, no efforts have been made to verify the hypothesis, so its correctness still needs further proving through practice. By making use of the finite element analysis software ANSYS, this paper carries out number simulations of the shear stress on the cross section of bending beam. By comparing the result of simulations with that of the hypothesis, this paper proves the distributing law of the shear stress assumed by material mechanics |
