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

open access: yesMetals, 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]

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.

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

open access: yesJixie 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

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 ...

Deformation mechanisms in nanotwinned metal nanopillars [PDF]

open access: yes, 2012
Nanotwinned metals are attractive in many applications because they simultaneously demonstrate high strength and high ductility, characteristics that are usually thought to be mutually exclusive.

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

open access: yesJournal 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.

A micromechanically motivated uncoupled model for ductile fracture prediction

open access: yes工程科学学报, 2017
This paper is a contribution to the ductile fracture prediction by the proposal of a new uncoupled ductile fracture criterion. In the new criterion, two typical void deformation models were carefully considered, with the plastic strain increment regarded

Prediction method for ductile crack initiation and growth resistance for pre-strained steel based on ductile damage model

open access: yesNihon Kikai Gakkai ronbunshu, 2023
This study aims to develop a numerical simulation-based method for predicting ductile crack growth resistance curve (R-curve) for pre-strained components for rational assessment of ductile crack growth controlling fracture for pre-strained structural ...
