粘弹性功能梯度材料/结构的多宗量反问题数值求解
基于时域分段自适应算法，提出一种求解粘弹性功能梯度材料反问题的数值方法，可方便导出位移对待识别参数的一阶导数递推表达。当时间步长变化时，可通过自适应计算保证位移及位移导数的计算精度。在此基础上，利用L-M 算法和测点的位移信息，可实现对均质/非均质粘弹性功能梯度材料/结构本构参数及荷载的单一/组合识别。通过算例对所提算法进行了验证，考虑了噪声对反演结果的影响。

基于数值模拟的牙周韧带本构模型参数识别的研究进展
牙周韧带(periodontal ligament,PDL)也称牙周膜,是连接牙齿和其周边牙槽骨的致密结缔组织,由含有细胞、血管和神经的基质和嵌入其中的胶原纤维构成。在对牙齿施加了正畸力后,正畸牙齿的PDL受压区发生骨吸收,受拉区发生骨重构,最终导致正畸牙齿的移动。
