Numerical simulation for studying constraint effect on ductile fracture initiation using complete Gurson model [PDF]

FME Transactions, 2010
Ductile fracture initiation in high-strength low alloyed welded steel joints is predicted using micromechanical complete Gurson model (CGM). The crack tip constraint and variation of stress triaxiality in ligament are considered on single-edge notch bend

Projection effects in cluster mass estimates : the case of MS2137

, 2005
We revisit the mass properties of the lensing cluster of galaxies MS2137-23 and assess the mutual agreement between cluster mass estimates based on lensing, X-rays and stellar dynamics.

Effect of asphericity in caustic mass estimates of galaxy clusters

, 2014
The caustic technique for measuring mass profiles of galaxy clusters relies on the assumption of spherical symmetry. When applied to aspherical galaxy clusters, the method yields mass estimates affected by the cluster orientation.

Fracture initiation in multi-phase materials: a systematic three-dimensional approach using a FFT-based solver

, 2016
This paper studies a two-phase material with a microstructure composed of a hard brittle reinforcement phase embedded in a soft ductile matrix. It addresses the full three-dimensional nature of the microstructure and macroscopic deformation.

A novel method for imitating true-triaxial stress path with conventional triaxial apparatus

Geomechanics and Geophysics for Geo-Energy and Geo-Resources
AbstractThe stress paths of the cylindrical specimen in the p–q stress space by controlling the ratio of the axial and the radial loading is guaranteed to be consistent with the cuboid specimen, a novel method for imitating true-triaxial stress path by conventional triaxial apparatus was presented.

Mergers of Unequal Mass Galaxies: Supermassive Black Hole Binary Evolution and Structure of Merger Remnants

, 2012
Galaxy centers are residing places for Super Massive Black Holes (SMBHs). Galaxy mergers bring SMBHs close together to form gravitationally bound binary systems which, if able to coalesce in less than a Hubble time, would be one of the most promising ...

Breaking of axial symmetry in excited heavy nuclei as identified in Giant Dipole Resonance data

, 2017
A recent theoretical prediction of a breaking of axial symmetry in quasi all heavy nuclei is confronted to a new critical analysis of photon strength functions of nuclei in the valley of stability.
