Fracture mode of glass plate subject to low-velocity impact: experimental investigation and finite element simulation

Mechanical Engineering Journal, 2019
An understanding of the impact response of glass plates is important to protect people from injury. We investigated the fracture mode of a float glass plate that fractured under a low-velocity impact and conducted a numerical simulation. First, an impact

Damage-cluster distributions and size effect on strength in compressive failure [PDF]

, 2012
We investigate compressive failure of heterogeneous materials on the basis of a continuous progressive damage model. The model explicitely accounts for tensile and shear local damage and reproduces the main features of compressive failure of brittle ...

Sensitivity to initial conditions in self-organized critical systems

, 2004
We discuss sensitivity to initial conditions in a model for avalanches in granular media displaying self-organized criticality. We show that damage, due to a small perturbation in initial conditions, does not spread.

Verification of damage model of ceramic matrix composites and analysis of cyclic deformation behavior

Nihon Kikai Gakkai ronbunshu, 2014
Ceramics are excellent in heat, abrasion and corrosion resistances, but their strength reliability for structural materials is not enough due to their brittle nature.
