Brittle–ductile transition during diamond turning of single crystal silicon carbide [PDF]

open access: yes, 2013
In this experimental study, diamond turning of single crystal 6H-SiC was performed at a cutting speed of 1 m/s on an ultra-precision diamond turning machine (Moore Nanotech 350 UPL) to elucidate the microscopic origin of ductile-regime machining ...

Experimental characterization and numerical modeling of micromechanical damage under different stress states [PDF]

open access: yes, 2013
The use of HSLA steels for the manufacture of automotive components is interesting from an engineering point of view. This family of steels, while possessing high strength, also has good formability and can be used in forming manufacturing processes.

A New Model for Void Coalescence by Internal Necking [PDF]

open access: yes, 2010
A micromechanical model for predicting the strain increment required to bring a damaged material element from the onset of void coalescence up to final fracture is developed based on simple kinematics arguments.

Study on Dependence of Ductile Fracture Progress on Grain-Boundary Due to FCC Tri-Crystal Model [PDF]

open access: yes, 2013
Based on shock wave theory one of the authors derived the criterion of the micro-crack nucleation, namely the micro-crack nucleation is caused by the jump of the velocity along the intersected crossing line between two different stationary discontinuity ...

Crystal Orientation Dependence on Deformation Localization and Ductile Fracture in FCC Tri-Crystal Materials [PDF]

open access: yes, 2012
On the basis of shock wave theory one of the author derived that the micro-crack nucleation is caused by the jump of the velocity along the intersected crossing line between two different stationary discontinuity bands characterized by vanishing velocity

Numerical prediction of structural steel flat and slant fracture modes using phenomenological shear fracture model

open access: yesJournal of King Saud University: Engineering Sciences, 2019
This paper presents the finite element (FE) predictions of structural steel flat and slant fracture modes using the phenomenological shear fracture model that employs the shear stress ratio instead of the lode angle parameter employed in literature for ...
