Studies into the Failure Prediction of Brittle Materials [PDF]

open access: yes, 1987
This thesis is divided into six chapters. The first chapter provides a brief introduction concerning the behaviour of brittle materials. It also contains the justification for the undertaking of the study as well as a brief description of the method ...

PM versus IM Ti-5Al-5V-5Mo-3Cr Alloy in Mechanical Properties and Fracture Behaviour [PDF]

open access: yesMaterials Research, 2019
The comparisons of mechanical properties and fracture behaviour between as-consolidated PM Ti-5553 alloy and as-cast IM Ti-5553 alloy were investigated through tensile, fracture toughness and impact toughness tests in this research.

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.

An adaptive finite element approximation of a variational model of brittle fracture [PDF]

open access: yes, 2010
The energy of the Francfort–Marigo model of brittle fracture can be approximated, in the sense of Gamma-convergence, by the Ambrosio–Tortorelli functional.

Strong embedded discontinuities for simulating fracture in quasi-brittle materials [PDF]

open access: yes, 2011
In this paper embedded strong discontinuities are used to model discrete cracking in materials like concrete. In the approach followed a discontinuous displacement field is considered and the deformation is localized at a surface of zero width.

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.%

Evaluation of delayed fracture property and fractography of notched specimens for high tensile strength steel

open access: yesNihon Kikai Gakkai ronbunshu, 2021
The evaluation of delayed fracture is essential owing to the widespread application of high-strength steel to reduce automotive weight. Furthermore, it is necessary to clarify the influence of local stress concentration at the notch root as delayed ...
