Thermal bending of thick rectangular plates of bimodulus composite materials

Wiighted residual solutions are presented for thermal bending of laminated composite plates. The material of each layer is assumed to be clastically and thermoelastically orthotropic and bimodular. The formulations are based on the thermoclastic version of the theory of Whitney-Pagano laminated plate, which includes thickness shear detormations. The results are obtained for deflections and neutral-surface positions and are found to be in good agreement with the closed-form solution.     

双模量复合材料正交迭层矩形厚板的热弯曲问题

本文给出了双模量复合材料迭层板热弯曲的加权残数解。各层都假定为弹性和热弹性的双模量各向异性材料。该模型是建立在Whitney-Pagano迭层板理论和热弹性模型基础上,考虑了沿板厚的剪切应变。所得挠度和中性面位置的结果和精确解非常吻合。
