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...

Numerical modeling of ductile fracture for high-strength metallic materials with a reformulated bond-level Gurson-type peridynamic model

This study presents a reformulated Gurson-type peridynamic model for the numerical simulation of ductile fracture in high-strength metallic materials. The approach is built within a non-ordinary state-based peridynamics framework and tightly couples the Gurson–Tvergaard–Needleman (GTN) model at the bond level. Specific...

Mesoscale modelling of void growth and fracture initiation in steel

Accurate prediction of ductile fracture in steels requires a mechanistic understanding of the evolution of microstructural voids under multiaxial loading. This work presents a mesoscale finite element framework implemented in Abaqus to characterise fracture initiation in structural steel using a representative volume e...

A Multiscale Analytical Model for Tensile Fatigue of Reinforced Thermoplastic Pipes Based on Continuum Damage Mechanics

To accurately predict the tensile fatigue life of reinforced thermoplastic pipes (RTPs) and clarify the mechanism of fatigue damage evolution, this research proposes a multiscale analytical model based on continuum damage mechanics (CDM). Built upon the three‐dimensional constitutive relations of RTPs and the load–de...

A continuum damage mechanics-based approach to study bolt clamping force effect on the fracture strength of a plate containing a fastener hole with symmetrical edge cracks

A numerical investigation is conducted to analyze the clamping force effect on the fracture strength of holed plates with symmetrical edge cracks, made from Al-Alloy7075-T6, subjected to longitudinal tensile load by quasi-brittle damage evolution, and the results were compared with the available experimental tests. The...

An extended state-based intermediately homogenized peridynamic model for concrete failure analysis considering the ITZ porosity

The interfacial transition zone (ITZ) is inherently a porous region that significantly influences macroscopic mechanical and fracture behaviors of concrete materials. In this study, an extended state-based intermediately homogenized peridynamic model (IH-PD) is proposed for concrete failure analysis considering the ITZ...
