From Brittle to Ductile Fracture in Disordered Materials [PDF]

, 2010
We introduce a lattice model able to describe damage and yielding in heterogeneous materials ranging from brittle to ductile ones. Ductile fracture surfaces, obtained when the system breaks once the strain is completely localized, are shown to correspond

Effects of Silicon on Mechanical Properties and Fracture Toughness of Heavy-Section Ductile Cast Iron

Metals, 2015
The effects of silicon (Si) on the mechanical properties and fracture toughness of heavy-section ductile cast iron were investigated to develop material for spent-nuclear-fuel containers. Two castings with different Si contents of 1.78 wt.% and 2.74 wt.%

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

, 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.

Rupture by damage accumulation in rocks [PDF]

, 2006
The deformation of rocks is associated with microcracks nucleation and propagation, i.e. damage. The accumulation of damage and its spatial localization lead to the creation of a macroscale discontinuity, so-called "fault" in geological terms, and to the

STUDY ON DUCTILE FRACTURE CRITERION PARAMETERS OF HIGH STRENGTH DUPLEX STEEL PLATE

Jixie qiangdu, 2023
In order to predict the ductile fracture failure of different high-strength steel plates, the damage parameters of the ductile fracture criterion were calibrated by designing the tensile, shear and fracture failure tests of four high-strength steel ...

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

Journal 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 ...

Mechanical Behavior and Permeability of Simulated Rock with Single Fracture under Brittle and Ductile Conditions

Journal of MMIJ, 2019
Gypsum aggregate specimens have been used in the present study, because brittle, semi-brittle and ductile stress-strain behaviors of the specimen can be controlled only with confining stress level at the room temperature.
