A systematic validation of this GFEM applied to 3-D fatigue crack propagation has not been reported in the literature. The Displacement Correlation Method (DCM) is used to extract stress intensity factors. The effect of material parameters adopted in the DCM on the crack growth rate and fracture shape is investigated. Three increasingly complex fatigue crack propagation problems are solved. The first involves mixed-mode loading in a modified compact tension specimen. The second one involves the transition from 2-D to 1-D crack surfaces and interactions between the crack front and the corners of the domain boundary. The final problem simulates the growth of a circumferential surface crack in a steel pipe subjected to fatigue bending with overloading, where interactions between the crack and the pipe’s inner surface result in the splitting of the crack front.

Firstly, the Abaqus implementation of the phase field to model intralaminar damage in composite laminates is established, exploiting the analogy between phase field and the heat transfer model to use Abaqus temperature as the phase field damage parameter. In addition, since residual stresses developed during manufacturing processes affect damage propagation, they are incorporated into the formulation as constant residual strains.

The new approach leverages MPM’s ability to handle large strains and complex failure mechanisms without the mesh entanglement issues common in Finite Element Methods. The elliptical failure surface model for ice is used, accommodating both tensile and compressive failure criteria within a unified framework. This model allows for an accurate representation of ice behavior under a variety of loading conditions and supports the simulation of spalling and crushing phenomena. We validate our numerical model against experimental data obtained in large-scale indentation tests, demonstrating its efficacy in replicating the observed variability in oscillations, load ranges, and average load values. The results indicate that MPM is a promising tool for numerical investigation of ice failure, capturing key features such as fragmentation patterns and load response more effectively than conventional methods.

While dissipation may be introduced through various chemical or physical mechanisms, at the continuum scale it is manifested in the hysteresis under a loading-unloading cycle.

Here we use finite element simulations to elucidate the mechanics of crack growth in soft inelastic solids. Specifically, we consider the pure shear configuration and adopt a phenomenological model to capture the Mullins effect. It is found that the apparent energy release rate continues to increase after the crack growth is initiated, resulting in a crack growth resistance curve. The physical origin of the resistance curve is attributed to the formation and expansion of a damage zone surrounding the crack tip. We use the simulation results to illustrate how the resistance curve is related to the force-stretch curve as well as their dependence on sample dimensions. Moreover, we discuss the interpretation of fracture toughness based on the resistance curve and the force-stretch curve.

This paper undertakes a study of the delamination of TBCs using multi-physics methodologies. Heat transfer was cyclically implemented into the TBC model, resulting in a thermal gradient, to simulate the in-service operation of the TBC system. A variational-based sintering model for a topcoat of TBCs is incorporated into the simulation. The high-temperature creep model of the topcoat, thermal growth oxide (TGO) and bond coat is included. The stress field across the TBCs was calculated during the thermal cycles, with the location of high-stress concentration selected as the potential crack initiation site. Phase field damage modelling was conducted to study crack propagation, initially located at the high-tensile stress off-peak interface. Results indicate that at the off-peak interface, the crack propagates rapidly in the top right direction during the first few cycles, then stops propagating as the TGO thickens, because the location of the maximum principal stress is moved away from the interface. Since the accumulated stress at the crack tip at the end of cycles, cracks have the potential to propagate with a prolonged thermal cycle service.</p></div>","PeriodicalId":590,"journal":{"name":"International Journal of Fracture","volume":"249 4","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10704-025-00874-y.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144880929","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, limited studies in the literature focus on modeling the fracture behavior of ALM structural elements, particularly using beam kinematics coupled with phase-field (PF) damage models to reduce computational costs than analyzing an equivalent 2D model. The present study develops a beam-based PF model using Timoshenko beam theory to simulate localized damage evolution in brittle ALM grids. The proposed model employs a homogenized damage function to capture the overall damage state across the beam cross-section, bypassing the need to resolve damage variations within the section. Two damage approximation functions, constant and parabolic, are explored to describe damage across the cross-section. Damage evolution is attributed to a combination of tensile axial energy, shear energy, and a fraction of flexural strain energy. A series of numerical simulations, from isolated beam tests to full-scale ALM grid analyses, demonstrate the efficacy of the proposed model. Results indicate that the fraction of flexural strain energy(<span>(alpha )</span>) influencing damage evolution varies with the beam’s depth-to-length ratio, while boundary conditions show negligible impact on <span>(alpha )</span> for a fixed ratio. Model validation through comparisons with 2D simulations and experimental data highlights accurate predictions of load-displacement responses and crack patterns. Moreover, the proposed approach achieves significant computational efficiency, reducing the degrees of freedom for the lattice system from 3.2 million in a 2D model to just 58,000. Correspondingly, computational time decreases from 14 hours and 43 minutes to only 7 minutes and 20 seconds. These results underscore the potential of the proposed beam-based PF model as a computationally efficient and accurate tool for analyzing damage behavior in ALM.</p></div>","PeriodicalId":590,"journal":{"name":"International Journal of Fracture","volume":"249 3","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144843324","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study demonstrates that, under small far-field strains, the crack tip field can be generally divided into three regions: Region I—the asymptotic neo-Hookean crack tip field as <span>(rrightarrow 0)</span>; Region II—a finite-radius nonlinear neo-Hookean zone; and Region III—an outer linear elastic region. Within Region III, a subregion may still obey the asymptotic linear elastic solution when the radial distance is sufficiently small. As the far-field strain increases, both the asymptotic linear subregion and the broader linear region shrink and eventually vanish, leaving only the nonlinear zones. This multiscale structure reflects the principle of small-scale nonlinearity, wherein nonlinear effects are confined to an inner core. The inner core consists of Region I, where asymptotic neo-Hookean fields dominate, and Region II, where general nonlinear effects prevail. Initially, this inner core is nested inside Region III. At sufficiently small far-field strains, Region III itself contains an inner core that follows asymptotic linear elastic crack tip fields. As loading intensifies, Regions I and II expand, and Region III—first its asymptotic core, then the broader linear zone – .- progressively diminishes, culminating in a large-scale nonlinearity regime. We also identify and quantify the characteristic length scales over which each region exists and dominates—nonlinear fields in Regions I and II and linear elastic behavior in Region III. An important point is that at the crack tip, Region I always governs the local field, although its extent may be small under small far-field strains, making it difficult to capture in computational simulations. To address this, we introduce a rescaling method to better resolve this near-tip behavior.</p></div>","PeriodicalId":590,"journal":{"name":"International Journal of Fracture","volume":"249 3","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-08-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10704-025-00880-0.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144832158","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
