Investigation of thickness and welding residual stress effects on fatigue crack growth

Ramy Gadallah et al.

Summary: This paper provides a numerical investigation on the influence of thickness and welding residual stress (WRS) on fatigue crack growth (FCG) for centrally cracked steel specimens. It discusses how thickness affects crack driving force and fatigue life when considering WRS. The study also examines the impact of mean stress (sigma m) on crack driving force and crack growth.

XFEM for semipermeable crack in piezoelectric material with Maxwell stress

J. Jena et al.

Summary: In this study, the extended finite element method (XFEM) is used to model semipermeable cracks in piezoelectric materials subjected to Maxwell stresses induced by an electric field. The crack tip is enriched with six-fold enrichment functions to accurately represent the semipermeable crack with Maxwell stress. The electro-mechanical interaction integral is modified and implemented for different crack configurations to calculate the stress intensity factor (SIF). The accuracy of the XFEM-based semipermeable crack model is demonstrated through validation with analytical solutions and the effects of various factors on the normalized SIF are investigated.

Efficient XFEM approach for the analysis of thin-walled beams

Ameer Marzok et al.

Summary: This paper presents a new approach to analyze thin-walled beams, which uses the eXtended Finite Element Method (XFEM) to add global enrichment functions to a standard 3D Finite Element (FE) coarse mesh. The resulting model bridges the gap between the Finite Prism Method (FPM) and a detailed 3D FE model, providing an efficient and accurate solution for thin-walled structures. The performance of the proposed method is superior to the FPM and a 3D FE model with a coarse mesh.

Effect of crack on shear buckling of CNTRC plates

Mohammad Hossein Taheri et al.

Summary: This paper presents a buckling analysis of cracked CNTRC plates under shear loading, with a focus on the presence of off-center cracks. The study uses numerical models and calculations to investigate the effect of different crack parameters on the critical buckling coefficient and mode shape. The results show that the interaction of various crack parameters affects the critical buckling mode shape, and the volume fraction and agglomeration of carbon nanotubes significantly impact the shear buckling capacity of the cracked CNTRC plates.

Xueyang Miao et al.

Summary: In this study, a dual-functional gradient carbon nanotube-reinforced composite is proposed, and the free vibration characteristics of rotating DFG-CNTRC laminated shells are investigated. A general model is established using orthogonal polynomials and the Rayleigh-Ritz method, and the effects of different factors on the traveling waves and modal characteristics are discussed.

A mixed XFEM and CZM approach for predicting progressive failure in advanced SiC/SiC CMC component

Amit Patel et al.

Summary: This research work focuses on simulating different fracture modes in the high-stress concentrated region of SiC/SiC CMC components at the macroscopic scale, considering the increasing cost and time of experimental tests. XFEM and CZM are used to predict mode-I and mode-II fracture behavior, respectively. The results show that the first crack initiation and propagation are dependent on XFEM damage criteria, and delamination occurs at the damage-front CE layers. The simulated force-displacement relationships match well with experimental results, indicating that XFEM with CZM methodology can be a reliable method for predicting fracture behavior in complex-shaped SiC/SiC CMC components in the near future.
