As a result, crack propagation path prediction and crack stability analysis are essential for predicting the integrity and durability of engineering structures. Internal crack growth is closely related to the quality and stability of engineering structures, according to a great amount of engineering practice. Studying and evaluating mechanical and structural components’ integrity is a particularly important task in engineering. The results of this modeling are validated in terms of crack growth trajectories and SIFs by several crack growth studies reported in the literature that show trustworthy results. Depending on the position of the hole, the results reveal that the crack propagates in the direction of the hole due to the uneven stresses at the crack tip, which are consequences of the hole’s influence. Under linear elastic fracture mechanics (LEFM), the maximum circumferential stress criterion is applied as a direction criterion.

The present study was carried out for two geometries, namely a cracked plate with four holes and a plate with a circular hole, and an edge crack with different pre-crack locations. If the hole is close enough to the crack path, the crack may stop at the edge of the hole, resulting in crack arrest. The presence of a hole near a propagating crack causes a deviation in the crack path. For this purpose, ANSYS Mechanical R19.2 was introduced with the use of a new feature known as Separating Morphing and Adaptive Remeshing Technology (SMART) dependent on the Unstructured Mesh Method (UMM), which can reduce the meshing time from up to several days to a few minutes, eliminating long preprocessing sessions.

The influence of the holes’ position and pre-crack locations in the crack growth direction were investigated. The aim of this paper was to present a numerical simulation of a crack growth path and associated stress intensity factors (SIFs) for linear elastic material.
