Numerical verification of energy release rate and J-Integral in large strain formulation
Forces in Mechanics, 2023 The fracture criterion is a critical topic in fracture mechanics. However, the equality of J-Integral (J) and energy release rate (G) has not been numerically verified under large strain theory.

An Elastic Interface Model for the Delamination of Bending-Extension Coupled Laminates
Applied Sciences, 2019 The paper addresses the problem of an interfacial crack in a multi-directional laminated beam with possible bending-extension coupling. A crack-tip element is considered as an assemblage of two sublaminates connected by an elastic-brittle interface of ...

Nanobeams with Internal Discontinuities: A Local/Nonlocal Approach
Nanomaterials, 2021 The aim of the present work is to extend the two-phase local/nonlocal stress-driven integral model (SDM) to the case of nanobeams with internal discontinuities: as a matter of fact, the original formulation avoids the presence of any discontinuities ...
