摘要
为了求解缝合层合板的弹性常数,基于用流场模型计算缝合单层弹性性能的思想,建立流场模型计算各种铺层方向缝合单层的弹性性能。以相应的流场模型为基础,结合细观力学方法和均匀化方法,计算了0°和45°缝合单层的弹性常数。最后应用改进的均匀化方法,求得了6组缝合层合板的弹性常数,计算结果与实验结果吻合较好。
Based on the idea of calculating elastic properties of the stitched laminar, a flow field model is set up to calculate the elastic properties of each laminar for the elastic properties of stitched laminates. Using the flow field models, the elastic properties of the 0° and 45° stitched laminar are calculated by the micromechanics and the homogenization method. The elastic constants of 6 sets of stitched laminates are calculated using the modified homogenization method, and the results are in good agreement with those of the test.
