Table 4 From An Eigenvalue Stabilization Technique For Immersed In this contribution a simple, robust and efficient stabilization technique for extended finite element (xfem) simulations is presented. it is useful for arbitrary crack geometries in two or three…. Referred to as the evs technique (eigenvalue stabilization) throughout the article, this method operates at the element level, ensuring minimal additional numerical costs and high parallelizability.
Table 5 From An Eigenvalue Stabilization Technique For Immersed A key advantage of the stabilization method lies in the fact that only element level operations are required. this is accomplished by computing all eigenvalues of the element matrices and subsequently introducing a stabilization term that mitigates the adverse effects of cutting. To tackle this challenge, we propose the use of a dedicated eigenvalue stabilization (evs) technique. the evs technique serves a dual purpose. In this article, we primarily focus on immersed boundary methods, specifically examining the finite cell method (fcm) [6–8] and spectral cell method (scm) [9,10], its extension to explicit dynamic problems. Immersed boundary methods provide a means of discretizing structures using cartesian grids, employing elements that do not conform to the boundary of the geometry of interest. however, this non conforming spatial discretization introduces three challenges that need to be addressed.

Immersed boundary methods provide a means of discretizing structures using cartesian grids, employing elements that do not conform to the boundary of the geometry of interest. however, this non conforming spatial discretization introduces three challenges that need to be addressed. To demonstrate the efficacy of our technique, we present two specifically selected dynamic benchmark examples related to wave propagation analysis, where an explicit time integration scheme must be employed to leverage the increase in the critical time step size. This paper presents a generalized eigenvalue stabilization (gevs) strategy for immersed boundary finite element methods to eliminate the adverse effect on the stability caused by cut elements using explicit time integration. Tl;dr: a novel eigenvalue stabilization technique is proposed to address the "small cut elements problem" in immersed boundary finite element methods, enabling robust and efficient analysis of high frequency transient problems in explicit dynamics with improved critical time step size. To overcome this problem, in this paper, we apply and adapt an eigenvalue stabilization technique to improve the ill conditioned matrices of the finite cells and to enhance the robustness for large deformation analysis.
