A mesh adaptation algorithm to reduce mesh bias in 2D and 3D crack propagation analysis using cohesive zone models

Year: 2025

Type: conference-paper

Abstract: This paper presents a novel mesh reorientation algorithm that enhances the reliability of crack path prediction in cohesive zone cracking models by reducing the inherent mesh bias.The proposed method realigns interface elements to maximize their local tensile traction, facilitating cracking in energetically more favorable direction.Extensive testing shows that the algorithm consistently improves results in 2D and 3D applications, enabling more reliable predictions, including cracks originating within the domain, without requiring crack tracking or pre-specifying crack initiation points.
