摘要
采用交替非线性分析有限元法研究了复合材料层合板在瞬态热载作用下的热变形问题。通过数值结果讨论表明,在研究热载作用下复合材料层合板热变形分析时必须考虑复合材料热物理和力学机械性质随温度变化的非线性特征。
This paper investigates nonlinear thermal deformations of composite laminates undertransient thermal loading by means of nonlinear finite element method based on an alternativeiteration algorithm,The temperature-dependent thermal conductive and mechanical properties ofcomposite materials are considered.Numerical results and discussion show that the nonlineareffect of thermal conductive and mechanical properties with varying temperature on thedistribution and magnitude of the deformations of composites laminates under transient thermalloading is considerable.
