Owing to the solution space enriched with a priori known knowledge through the partition of unity, the extended or generalized finite element method (XFEM/GFEM) has been widely …
Robustness and stability of the Continuum Strong Discontinuity Approach (CSDA) to material failure are addressed. After identification of lack of symmetry of the finite element …
In this paper, strong discontinuities are embedded in finite elements to describe fracture in quasi-brittle materials. A new formulation is presented in which global nodes are introduced …
One of the dominant characteristics of Arctic ice is the development and persistence of leads. Leads are critically important for climate modeling since they are a source for new ice …
This paper presents the first unified finite element strategy for coupled hydro-mechanical (HM) analysis of fractured porous media where cracks arbitrarily intersect standard finite …
