Comparison of the constraint parameters in elastic-plastic fracture mechanics

Fracture and Structural Integrity, 2019
To describe the effect of crack-tip constraint on the stress field for finite cracked bodies, the following most widely used constraint parameters can be employed in elastic-plastic fracture mechanics, namely, local triaxiality parameter, constraint ...

Does the continuum theory of dynamic fracture work?

, 2002
We investigate the validity of the Linear Elastic Fracture Mechanics approach to dynamic fracture. We first test the predictions in a lattice simulation, using a formula of Eshelby for the time-dependent Stress Intensity Factor.

On the Rigidity and Mechanical Behavior of Triply Periodic Minimal Surfaces‐Based Lattices: Insights from Extensive Experiments and Simulations

Advanced Engineering Materials, EarlyView.
This study examines the mechanical properties of triply periodic minimal surfaces (TPMS)‐based lattices, analyzing 36 architectures in elastic and plastic regimes. It evaluates the applicability of beam‐based scaling laws to TPMS lattices. Rigidity arises from the alignment of members with the load direction and solid regions preventing rotation.

Variational problems in fracture mechanics

, 2006
We present some recent existence results for the variational model of crack growth in brittle materials proposed by Francfort and Marigo in 1998. These results, obtained in collaboration with Francfort and Toader, cover the case of arbitrary space ...

Synergistic Effects of Cerium and Magnesium on Optimizing Electrical Conductivity and Mechanical Properties of AlSi3 Cast Alloys

Advanced Engineering Materials, EarlyView.
This study investigates the impact of Ce and/or Mg on the electrical conductivity (EC) and mechanical properties of AlSi3 cast alloy. It highlights the synergistic effects of Ce and Mg on eutectic Si modification and Mg solute reduction in the Al matrix, resulting in the optimization of EC, strength, and ductility of the alloy.

Hierarchical multiscale fracture modeling of carbon-nitride nanosheet reinforced composites by combining cohesive phase-field and molecular dynamics [PDF]

arXiv
Understanding the fracture mechanisms in composite materials across scales, from nano- to micro-scales, is essential for an in-depth understanding of the reinforcement mechanisms and designing the next generation of lightweight, high-strength composites.

Influence of a Hydrogen Addition to the Inert Gas and Subsequent Heat Treatments on the Microstructure and Mechanical Properties of Magnesium WE43 Fabricated by PBF‐LB/M

Advanced Engineering Materials, EarlyView.
This article investigates optimal processing conditions for the laser‐based powder bed fusion of WE43. To limit the interaction with remaining oxygen, a 3 vol% hydrogen admixture to the inert gas is investigated. Furthermore, heat treatments are investigated in the range of 250–350 °C for 48 h.

Disorder protects collagen networks from fracture [PDF]

arXiv, 2019
Collagen forms the structural scaffold of connective tissues in all mammals. Tissues are remarkably resistant against mechanical deformations because collagen molecules hierarchically self-assemble in fibrous networks that stiffen with increasing strain.

Mechanical and fracture properties of particleboard

Frattura ed Integrità Strutturale, 2018
Particleboard (PB) are woodbased composites with fine wood fibers bound together by a small amount of polymeric adhesive, widely used in furniture industry and civil engineering. PB plates can be painted, laminated or veneered, and have good dimensional stability and load bearing capacity when properly designed. However, the deformation and fracture of
