Mode I crack tip fields: strain gradient plasticity theory versus J2 flow theory
Emilio Martínez-Pañeda, Norman A. Fleck
The mode I crack tip asymptotic response of a solid characterised by strain gradient plasticity is investigated. It is found that elastic strains dominate plastic strains near the…
The role of plastic strain gradients in the crack growth resistance of metals
Emilio Martínez-Pañeda, Vikram S. Deshpande, Christian F. Niordson +1
Crack advance from short or long pre-cracks is predicted by the progressive failure of a cohesive zone in a strain gradient, elasto-plastic solid. The presence of strain gradients…
Compressive Behavior and Failure Mechanisms of Freestanding and Composite 3D Graphitic Foams
Kenichi Nakanishi, Adrianus I. Aria, Matthew Berwind +4
Open-cell graphitic foams were fabricated by chemical vapor deposition using nickel templates and their compressive responses were measured over a range of relative densities. The…
