Stress concentration near stiff inclusions: validation of rigid inclusion model and boundary layers by means of photoelasticity

D Misseroni, F Dal Corso, S Shahzad… - Engineering Fracture …, 2014 - Elsevier
Photoelasticity is employed to investigate the stress state near stiff rectangular and
rhombohedral inclusions embedded in a 'soft'elastic plate. Results show that the singular …

Energy release rate, the crack closure integral and admissible singular fields in fracture mechanics

A Piccolroaz, D Peck, M Wrobel, G Mishuris - International Journal of …, 2021 - Elsevier
One of the assumptions of Linear Elastic Fracture Mechanics is that the crack faces are

Dispersion of rigid line inclusions as stiffeners and shear band instability triggers

M Goudarzi, F Dal Corso, D Bigoni… - International Journal of …, 2021 - iris.unitn.it
A dispersion of stiff and thin ('rigid line') inclusions (RLIs) in a matrix material may result
beneficial for stiffening in the elastic range, but might be detrimental to strength, as material …

Numerical evaluation of the interaction of rigid line inclusions using strain intensity factors

TM Jobin, M Ramji, SN Khaderi - International Journal of Mechanical …, 2019 - Elsevier
The elastic interaction of two rigid line inclusions is analyzed when the inclusions are
embedded in a finite matrix. The boundary element method is used to solve for the elastic …

On numerical solving a rigid inclusions problem in 2D elasticity

E Rudoy - Zeitschrift für angewandte Mathematik und Physik, 2017 - Springer
A 2D elastic problem for a body containing a set of bulk and thin rigid inclusions of arbitrary
shapes is considered. It is assumed that rigid inclusions are bonded into elastic matrix. To …

On the blocking and shearing interaction of shear bands in Pd, Zr, and Cu-based monolithic metallic glasses

S Bouzayeni, H Ghulman, T Benameur - Journal of Materials Engineering …, 2023 - Springer
Shear bands (SBs) play an important role in controlling plastic flow, identifying large shear
strain, and detecting failure in metallic glass (MG). Interaction between individual SBs by a …
