| 摘 要： | 运用弹性力学理论和经典层合板理论,推导了有弹性地基作用情况下,复合材料曲梁弯曲时径向应力的计算公式,该公式还可以得到曲梁纯弯曲情况下的解析解。利用所推导的公式,讨论了弹性地基对复合材料曲梁径向应力以及径向最大应力位置的影响。 |
| 关 键 词： | 复合材料 曲梁 径向应力 弹性地基 |

| Abstract: | An elasticity-theory-based approach and a classical laminated plate theory are combined to obtain the expression of the through-thickness stresses in curved layered composite beams on an elastic foundation under flexural loading.With this expression,the solution to through-thickness stresses in curved layered composite beams under pure bending can also be achieved.The influence of the elastic foundation on through-thickness stresses and the location of the maximal through-thickness stresses in curved layere... |
