TY - EJOU AU - Park, Jai Hak TI - A Review on Finite Element Alternating Methods for Analyzing 2D and 3D Cracks T2 - Digital Engineering and Digital Twin PY - 2024 VL - 2 IS - 1 SN - AB - A finite element alternating method has been known as a very convenient and accurate method to solve two and three-dimensional crack problems. In this method, a general crack problem is solved by a superposition of two solutions. One is a finite element solution for a finite body without a crack, and the other is an analytical solution for a crack in an infinite body. Since a crack is not considered in a finite element model, generating a model is very simple. The method is especially very convenient for a fatigue crack growth simulation. Over the past 40 years, S. N. Atluri and his many collaborators have developed finite element alternating methods for two and three-dimensional cracks. In this paper, the developing history of the finite element alternating method was reviewed to understand the current status of the method. From this review process, it can be known what kinds of crack problems can be solved accurately with the current method, and what part of the method needs to be improved further.
