The evolution of the dynamic weak layer fracture likely determines the size or destructive potential once release takes place. In this paper, 54 values of mode II fracture speed collected from field tests are analyzed. In addition, values of speed collected with connection with avalanche release which involves both mode II and mode III shear fracture are analyzed. The Rayleigh wave speed is the normal maximum speed limit for a mode II fracture based on continuum formulations and the shear wave speed is the companion speed limit for mode III fracture. The 54 values of speed data from field tests are shown to have a median value of 12% of the predicted Rayleigh wave speed with a range between 2 and 56%. The data collected during avalanche release do not exceed 59% of the Rayleigh wave speed. The test data were collected from weak layers composed of highly porous crystal forms which are known to exhibit dynamic porosity loss during fracture propagation. Such events imply viscous dissipation and high friction which help to explain the low speeds. For snow slab avalanche release, which occurs for slope angles greater than <span>(25^{0})</span>, field observations show that the mixed mode (II, III) weak layer fracture terminates with mode I fracture through the slab following dynamic propagation. Analysis using the avalanche speed data with respect to terminal mode I fracture suggests that the shear stress drop behind the fracture process zone can contribute to produce the mode I fracture to promote avalanche release but dynamic contraction of the fracture process zone is a minor effect at best.</p></div>","PeriodicalId":590,"journal":{"name":"International Journal of Fracture","volume":"249 4","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-10-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145315843","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}

As is consistent with the classical gradient damage theory, the eikonal-type gradient damage modeling framework is mesh-independent and simple to implement, as it does not require any numerical tracking algorithm for discontinuities in the displacement field during crack propagation. With the evolving interaction known as the damage-based transient internal length scale, eikonal damage formulations could overcome the drawbacks of spurious damage diffusion and incorrect damage initiation by the traditional gradient theory. More realistic failure behavior could be predicted by the eikonal-based damage models.

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.

To tackle this, a simple phase field formulation to model the onset and propagation of transverse damage in highly curved laminates is presented. 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. Secondly, the proposed implementation is validated by performing tests on benchmark problems. Finally, a preliminary analysis of the unfolding failure test is provided to highlight the importance of including residual stresses in the transverse damage evolution.</p></div>","PeriodicalId":590,"journal":{"name":"International Journal of Fracture","volume":"249 4","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-09-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1007/s10704-025-00877-9.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145057636","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}

A new numerical approach to simulate the crushing and spalling behavior of ice using the Material Point Method (MPM) is presented. Ice behavior under general triaxial load involves complex processes such as pressure softening, crack formation, fragmentation, and large deformations of crushed particles, which are challenging to capture with traditional simulation methods. 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. Such inelastic behavior, resembling the Mullins effect in filled rubber, may lead to ambiguities in the interpretation of fracture toughness measurements. 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. Our results can provide guidance to experimental characterization of fracture toughness in soft inelastic solids.</p></div>","PeriodicalId":590,"journal":{"name":"International Journal of Fracture","volume":"249 4","pages":""},"PeriodicalIF":2.5,"publicationDate":"2025-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144891455","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}
