| 摘 要： | 采用三维有限单元法分别对单一与复合材料的等截面梁进行数值模拟,并与梁的挠曲线的近似微分方程的计算结果进行比较,得出结论:对实心截面梁,无论单一材料或复合材料,只要跨高比小于5:1,剪力对挠度的影响不可忽略;跨高比大于9:1时,挠曲线近似微分方程的精度是足够的。

| Abstract: | By using 3D solid element,the paper computes bending deflection of a solid section beam made of single or combined material at different l/h ratio,and compares the results with the solutions of approximate differential equation of the beam deflection and emphasizes that influence of the shearing force on the bending deflection must all be considered for the beam with either combined or single material when l/h ratio is less than 5 or it is ignorable if it is more than 9. |
