多层异料组合梁弯曲的弹性理论解

The Accurate Solution of Composite Materials Beam Based on The Theory of Elasticity

本文分层引入四次多项式应力函数,给出自由端承受集中力和集中力偶的n层异料组合梁弯曲应力的弹性力学解;讨论该问题的初等分析中采用Bernouli变形假设的合理性。

According to the different interlaminar stress function, this Paper gives the accurate solution of composite materials beam, Under the concentric load and couple on it's free end. Which is based on theory of elasticity. And disscussing the reasonation of Bernouli assumption in prim-ary analyse about this problem. This paper has a certain theoretical mean-ing.
