Attractive and repulsive cracks in a heterogeneous material

, 2008
We study experimentally the paths of an assembly of cracks growing in interaction in a heterogeneous two-dimensional elastic brittle material submitted to uniaxial stress.

Fatigue crack growth of aluminium alloy 7075-T651 under non-proportional mixed mode I and II loads [PDF]

Fracture and Structural Integrity, 2016
This study aims to investigate fatigue growth behaviour in AA7075-T651 under non-proportional mixed mode I and II loads. Fatigue tests were performed under cyclic tension and torsion using a thin-walled tubular specimen with a key-hole style crack ...

Crack path selection at the interface of wrought and wire+arc additive manufactured Ti–6Al–4V [PDF]

, 2016
Crack propagation deviation tendency in specimens containing an interface between wrought alloy substrate and Wire + Arc Additive Manufacture (WAAM) built Ti–6Al–4V is investigated from the viewpoints of microstructure, residual stress and bi-material ...

Elevated temperature crack growth [PDF]

The purpose of this program was to extend the work performed in the base program (CR 182247) into the regime of time-dependent crack growth under isothermal and thermal mechanical fatigue (TMF) loading, where creep deformation also influences the crack ...

The dynamics of cracks in torn thin sheets

, 2010
Motivated by recent experiments, we present a study of the dynamics of cracks in thin sheets. While the equations of elasticity for thin plates are well known, there remains the question of path selection for a propagating crack.

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

FEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

Research of Fatigue Crack Growth Based on Critical Plane Method

MATEC Web of Conferences, 2016
To precisely simulate the path of crack growth, a simulation of crack growth progress has been presented by using the redevelopment function of ANSYS APDL and introducing the random criterion of crack propagate directions with critical plane approach ...
