Analysis of a Crack in a Thin Adhesive Layer between Orthotropic Materials: An Application to Composite Interlaminar Fracture Toughness Test [PDF]

, 2010
The problem of a crack in a thin adhesive layer is considered. The adherents may have orthotropic elastic behavior which allows composite laminates to be modeled. In the present work a linear elastic-brittle constitutive law of the thin adhesive layer,

Interface delamination vs. bulk cracking along wavy interfaces

Engineering Fracture Mechanics, 2019
Abstract This paper analyzes the competition between bulk cracking and interface delamination along a wavy interface. The simulations embed cohesive elements throughout the entire mesh of conventional elements, such that crack paths emerge as a natural outcome of the simulations.

Unlocking the Power of Quercetin‐Encapsulated Mesoporous Bioactive Glass Nanoparticles: A Multifunctional Approach to Bone Regeneration

Advanced Engineering Materials, EarlyView.
Mesoporous bioactive glass nanoparticles (MBGNs) are investigated for bone regeneration given their remarkable structural and functional properties. MBGNs are functionalized with Mn and Cu and incorporated with quercetin, a natural flavonoid exhibiting antioxidant, anti‐inflammatory, and antimicrobial properties.

Fracture mechanics analysis for various fiber/matrix interface loadings [PDF]

Fiber/matrix (F/M) cracking was analyzed to provide better understanding and guidance in developing F/M interface fracture toughness tests. Two configurations, corresponding to F/M cracking at a broken fiber and at the free edge, were investigated.
