HDQM is a combined method with WDQM being used in the longitudinal direction due to its superiority in treating singularity and GDQM in the thickness direction for its higher computational efficiency.

• 由于小波对突变信号具有良好的自适应描述能力，因此在平板宽度方向上，利用小波微分求积法可以有效地处理集中荷载；而在材料梯度变化的板厚方向上，则利用广义微分求积法计算量小且精度高的特点进行离散计算。
