Systematic analysis of damage irreversibility enforcement in phase-field fracture models

Numerical Methods and Algorithms for Phase-Field Fracture Modeling

Fracture mechanics is essential for predicting the failure of materials and structures. The Phase-Field Fracture (PFF) method has emerged as a powerful computational tool, overcoming the limitations of classical discrete approaches by modeling cracks as diffuse damage bands. This formulation eliminates the need for exp...

Dynamic fracture modeling in ductile materials using phase field approach

Understanding dynamic fracture in both brittle and ductile materials has attracted considerable attention from engineers and researchers due to its practical importance. In ductile materials, crack initiation and growth are strongly influenced by plastic deformation and the associated microstructural damage, which grad...

Data-Driven Cohesive Zone Modeling within the Generalized Standard Materials Framework

Cohesive zone models are widely used to describe fracture and interfacial failure, yet most formulations prescribe problem-specific analytical traction-separation laws together with phenomenological rules for unloading and reloading, leading to specialized models for different cohesive behaviors. This work develops a u...
