MS11 - Advances in Computational Plasticity, Damage and Fracture

Single Point Incremental Forming (SPIF) is an innovative forming technique in which a stylus forming tool incrementally deforms a blank sheet into the final shape. The deformation mechanism is quite different compared to traditional forming processes. Moreover, fracture prediction remains a significant challenge. In the current study, a hybrid experimental–numerical approach was conducted to...

MS11 - Advances in Computational Plasticity, Damage and Fracture

Numerical simulations of quasi-static crack propagation in brittle materials often suffer from numerical instabilities, such as snapback events, due to structural softening.
In variational phase-field fracture models, these instabilities manifest as abrupt crack jumps, thereby impeding physical validity, as the energy minimization is performed over a significant crack increment.
Moreover,...

Variational approach to dynamic cohesive fractures

key words : variational methods, phase-field models, cohesive fracture, damage-plasticity models, dynamics

Gradient damage models (aka phase-field models) are widely used to predict the nucleation and propagation of cracks. Recently, a novel class of phase-field models based on coupled damage-plasticity models have been developed....

144. Numerical Benchmarking of Phase-Field Fracture Implementations Across Open-Source and Commercial Finite Element Frameworks

Stefano Domesi (Sapienza University of Rome)

MS11 - Advances in Computational Plasticity, Damage and Fracture

Phase-field models for brittle fracture have become a widely adopted tool for simulating crack initiation and propagation without explicit tracking algorithms. As their popularity has grown, so has the variety of available implementation strategies, encompassing different solvers, coupling schemes, irreversibility treatments, and software platforms. While each approach has been individually...

157. Modeling the Creep Behavior of Cracked Concrete Beams Strengthened with Externally Bonded FRP Plates Using a Cohesive Zone Approach

Khamis Hadjazi (Composite Structures and Innovative Materials Laboratory (LSCMI), Faculty of Mechanic Engineering, University of Science and Technology of Oran (USTO), Oran)

MS11 - Advances in Computational Plasticity, Damage and Fracture

This study presents a creep response model to investigate the long-term behavior of interfacial shear stresses induced by intermediate flexural cracks in reinforced concrete beams strengthened with externally bonded fiber-reinforced polymer (FRP) plates. A theoretical framework based on a bi-linear cohesive zone model is developed to describe intermediate crack-induced debonding. The proposed...
