Shear cutting, a crucial process in sheet metal forming, often leads to microcracks and plastic deformation that degrades the material performance in subsequent applications, such as cold forming, crashworthiness, and fatigue resistance. This work utilises the Particle Finite Element Method as an alternative to conventional Finite Element Methods to address the challenges of large deformation solid mechanics, offering high predictive accuracy in localised shearing deformation and fracture. The model was validated against experimental data from sheet punching tests, with evaluations at both macroscopic and mesoscopic levels, including cut edge profiles and microstructural deformation within the shear-affected zone. The Particle Finite Element Method approach demonstrated a high level of accuracy in predicting cut edge shape and shear-induced damage across various cutting conditions.

While classical approaches have proven their accuracy and robustness over the years and come with a rich mathematical foundation, they suffer from several limitations depending of the underlying physics and use cases. For instance, especially concerning the resolution of Partial Differential Equations (PDEs) in 3 dimensions (3D), classical approaches are known to be computationally expensive. However, it turns out that simple pure data-driven approaches, while allegedly much more efficient from a computational point of view, do not necessarily hold up well regarding physical considerations. In this work, our aim is to investigate the tradeoff between accuracy and computational cost to design efficient and robust physical simulation methods under industrial constraints. In particular, as it is not easy to generate a large dataset through numerical simulations for such a problem, our aim is to design an approach addressing the data scarcity issue.

The proposed approach combines classical thermoporoelasticity theory with a cohesive fracture model to describe the coupled behaviors of fluid flow, rock deformation and fracture propagation. Within this framework, fractures are represented using constant strain triangular elements enriched with constant displacement jumps. The mechanical response of fractures is governed by a trilinear cohesive law, and fracture initiation and propagation are both determined by using standard Newton’s method while maintaining global equilibrium. The numerical framework is verified through a series of examples, including cases without fractures, cases with rigid and deformable fractures, and hydraulic fracture propagation with thermal effects. The results show that thermal stress primarily affects the region near the injection point but has limited impact on fracture length evolution and fluid pressure distribution within the fracture. In contrast, temperature-dependent viscosity can significantly influence hydraulic fracture propagation. This work can be beneficial to our understanding of hydraulic fracture modeling in thermoporoelastic media and provide a potential useful numerical tool for simulating hydraulic fracturing processes with consideration of thermal effects.</div></div>","PeriodicalId":56133,"journal":{"name":"Finite Elements in Analysis and Design","volume":"246 ","pages":"Article 104320"},"PeriodicalIF":3.5,"publicationDate":"2025-02-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143387536","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}

A robust active sensing framework that integrates model-based inference and optimal sensor placement is proposed. By tightly coupling measured data and data acquisition scenarios, a <em>simultaneous</em> approach of damage estimation and sensor placement can be used to continuously and accurately assess a structure. In this work, a partial differential equation-constrained formulation for damage estimation is first developed using a conventional model-updating approach with a penalization damage parameter. Then, this formulation is linearized around the damage estimator to produce an Optimal Experimental Design (OED) problem for desirable sensor locations. Hence, the simultaneous sensing framework is postulated using a Fisher Information Matrix (FIM)-based approach as follows: given a current candidate damage state associated with the most up-to-date sensor information, find the next sensor location that minimizes some metric of the FIM and update the damage estimator. The sensing framework is also enhanced by introducing a Modified Error in Constitutive Equations (MECE) functional in the damage estimator. Adding MECE makes the framework more robust by limiting the damage estimator from being trapped in local minima. Through numerical examples, we show that our approach produces accurate damage estimators using a small number of sensor locations.

The magnitude and distribution of residual stresses in arterial wall tissue affect the location of the occurrence of instabilities such as bulges. This study aims to develop a new approach to assess material behavior during bifurcation instability in the presence of residual stresses, especially non-planar stresses. A finite element protocol is developed for bifurcation and post-bifurcation of residually stressed thick-walled hyper-elastic circular hollow tubes subjected to axial stretches and internal pressure, incorporating three-dimensional residual stresses. A constitutive equation based on the strain energy function for these tubes is formulated and implemented in ABAQUS, using the Modified Riks method and a user-defined material subroutine (UMAT). Results indicate that bending bifurcation is likely for small axial stretches but becomes less probable with larger axial stretches while bulging bifurcation is expected for all axial stretch values. Pressures associated with pure bulging modes are higher than those for bulging induced by bending, suggesting aneurysms can be delayed by avoiding bending bifurcation. The bulging from bending bifurcation occurs on one side of the tubes, reflecting abdominal aortic aneurysm (AAA) conditions. The unsymmetrical bulge development aligns with the methodology used, whereas balloon-like bulging in pure modes is linked to arterial rupture.</div></div>","PeriodicalId":56133,"journal":{"name":"Finite Elements in Analysis and Design","volume":"244 ","pages":"Article 104309"},"PeriodicalIF":3.5,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142935962","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}
