Soft biological tissues are complex materials with a large structural variety, with differences
in behavior, but with some common characteristics. Skin is an archetypal soft tissue which …

扩展有限元法(extended finite element method, XFEM) 是1999 年提出的一种求解不连续力学
问题的数值方法, 它继承了常规有限元法(CFEM) 的所有优点, 在模拟界面, 裂纹生长 …

One of the first courses I taught at Stanford was Advanced Soil Mechanics. The course title
was accurate in the beginning, but the contents gradually became more and more about …

The failure behavior of geological materials depends heavily on confining pressure and
strain rate. Under a relatively low confining pressure, these materials tend to fail by brittle …

The extended finite element method (X-FEM) is a numerical method for modeling strong
(displacement) as well as weak (strain) discontinuities within a standard finite element …

Mechanically-based numerical modeling is a powerful tool for investigating fundamental
processes associated with the formation and evolution of both large and small-scale …

This paper presents new finite elements that incorporate strong discontinuities with linear
interpolations of the displacement jumps for the modeling of failure in solids. The cases of …

Geologic shear fractures such as faults and slip surfaces involve marked friction along the
discontinuities as they are subjected to significant confining pressures. This friction plays a …

Due to its computational robustness and versatility, the phase field fracture model has
become the preferred tool for predicting a wide range of cracking phenomena. However, in …

Accurate prediction of strength in rocks with distinct bedding planes requires knowledge of
the bedding plane orientation relative to the load direction. Thermal softening adds …
