Academy of Mathematics and Systems Science, CAS Colloquia & Seminars：3D Fracture Development Analysis with A Modified XFEM
XFEM 三维裂缝 发育分析
2023/11/6
扩展有限元法(XFEM)是目前裂纹分析的主流数值方法。2009年起，ABAQUS、ANSYS等主流商业软件集成XFEM并应用于裂纹问题，标志着该方法被工业界广泛接受。然而，在实际应用中XFEM仍然受到两方面的困扰：总体方程高度病态和动力学计算时能量难以守恒。基于“困难的根源在于单位分解插值引入的额外自由度”这一判断和认识，我们提出了一种无额外自由度的改进型扩展有限元方法，有效解决了现有方法总体刚度...
By examining earthquake models from a fresh perspective, Cornell engineers now show that the earthquake fracture energy – once thought to relate to how faults in the Earth’s crust weaken – is related ...

Systematic reviews meta-analysis randomized controlled trials
2016/6/12
A key aim when conducting systematic reviews of
randomized controlled trials (RCTs) is to include all of the evidence,
if possible. Serious bias may result if trials are missed
through inadequate s...
