“…Figure 13 reports the fatigue life diagrams. The graphs highlight that the predictions of the proposed method agree very well with the numerical results of Deng et al 27 and Jameel and Harmain, 68 also by varying the vertical position of the hole inside the plate. In particular, Figure 13 denotes that fatigue life increases with the increment of the hole's distance from the initial notch.…”

“…11 Because of such drawbacks, the fatigue life estimation of a material component is increasingly analyzed using numerical simulations. The clear advantages provided by numerical simulations as means of analysis have led to the development of different numerical approaches for reproducing fatigue crack propagation phenomena, such as the finite element method (FEM), [21][22][23][24] the extended finite element method (XFEM), 8,[25][26][27][28] or traditional meshless methods. 29,30 The FEM is the most renowned approach to studying fatigue and fracture mechanics problems because of its widespread diffusion and simplicity in modeling complex structures and advanced solid mechanics problems.…”

This work proposes a finite element (FE)‐based numerical model that uses the moving mesh technique for simulating fatigue crack propagation phenomena inside material components subjected to cyclic loads. Precisely, the computational mesh is adjusted during the numerical simulation according to conditions dictated by the criteria of fracture mechanics. Unlike standard FE procedures, which perform remeshing for each increment of the crack length, the proposed model updates the computational mesh only when FEs are distorted excessively because of the mesh nodes' motion, thus reducing computational burdens considerably. The validity of the proposed method is assessed through comparisons with existing experimental and numerical results.

“…Ding et al 36 performed variable node XFEM to simulate multiple crack growth in brittle materials using object-oriented programing. Deng et al 37 performed fatigue crack growth simulation using variable node XFEM approach. He concludes that local mesh refinement with variable node element approach is suitable for fatigue crack growth propagation and for future scope the presented formulation can be extended to simulate the fatigue crack growth propagations of functional graded materials under the thermal loading.…”

A novel computational approach presented in this work to improve the accuracy and efficiency of fracture modeling in an orthotropic material medium. Extended finite element method (XFEM) with higher-order enrichment functions was employed at the different scale mesh topology. The approach combined variable node element concepts for different scale mesh connections and higher-order XFEM for accuracy and completeness of discontinuity domain. The proposed computational methodology was employed with in-house developed MATLAB code. Further, stochastic fracture studies were discussed for reliability of the cracked structures. Few numerical examples with multiple geometrical discontinuities were simulated to check the computational efficiency and accuracy.

This study investigated the effect of fabric parameters on crack propagation in plain‐woven e‐glass reinforced epoxy composite plates. Through numerical analyses, the study contributes to understanding the effect of fabric structure on crack propagation and adopting a more precise approach in the design of composite materials. The yarn fiber volume fraction, shear angle, and yarn spacing parameters were selected as variables for the plain‐woven fabric, and material properties were determined for each parameter using the composite homogenization method. A finite element model was created using the Ansys software package, and stress intensity factors (SIFs) and tear stress values were obtained under mode I loading to investigate the effects of fabric structure on crack propagation. The results showed that as the yarn fiber volume fraction ratio increased, the SIF values decreased and the T‐stress values increased. When evaluated according to the shear angle of the yarn, the lowest SIF value was obtained for the 0‐degree shear angle. The same was observed for T‐stress values as well. Additionally, compared to the fabric structure aligned along the X‐axis, a significant decrease occurred in the SIF value due to the perpendicular fiber density increase to the crack propagation direction with symmetric orientation.
