| 1 | Adaptive phase field modelling of crack propagation in orthotropic functionally graded materials显示文摘In this work,we extend the recently proposed adaptive phase field method to model fracture in orthotropic functionally graded materials(FGMs).A recovery type error indicator combined with quadtree decomposition is employed for adaptive mesh refinement.The proposed approach is capable of capturing the fracture process with a localized mesh refinement that provides notable gains in computational efficiency.The implementation is validated against experimental data and other numerical experiments on orthotropic materials with different material orientations.The results reveal an increase in the stiffness and the maximum force with increasing material orientation angle.The study is then extended to the analysis of orthotropic FGMs.It is observed that,if the gradation in fracture properties is neglected,the material gradient plays a secondary role,with the fracture behaviour being dominated by the orthotropy of the material.However,when the toughness increases along the crack propagation path,a substantial gain in fracture resistance is observed. | Hirshikesh Emilio Martínez-Paneda Sundararajan Natarajan | 2021 | Defence Technology(防务技术)2021，17，1： | 0 |
| 2 | 混凝土相场断裂模拟——影响裂纹宽度的因素显示文摘混凝土的断裂特性对工程安全起着关键作用。相场断裂法能方便地模拟出裂纹的动态扩展过程,利用UEL和UMAT子程序,实现混凝土相场断裂的Abaqus二次开发,分析了单元尺寸和长度尺度参数对三点弯曲混凝土梁裂纹扩展宽度的影响。研究结果表明:当单元尺寸足够小时,裂纹宽度将不再受单元尺寸的影响,裂纹宽度随长度尺度参数减小而减小。 | 潘军 王鸿 赵冰 徐亚星 李涛峰 龙承运 | 2022 | 交通科学与工程2022，38，1： | 0 |
