摘要
纤维缠绕固体发动机壳体在内压试验爆破之前,体常常发生一定规律分布的裂纹.采用细观力学原理,研究了基体裂纹对角铺设层合板刚度的影响,结果表明该影响比较明显.最后讨论了刚度变化与铺设角等之间的关系.
In the paper,using principium of fine structural mechanics,the influence of the matrix cracks on the stiffness of the laminated shell of angle ply was studied.The results show that the influence is striking.Finally,the relationship between the angle and the change of the stiffness was discussed.
