The role of T-stress in brittle fracture for linear elastic materials under mixed-mode loading
The purpose of this paper is to revisit the maximum tensile stress (MTS) criterion to predict brittle fracture for mixed mode conditions. Earlier experimental results for brittle fracture ofExpand

Wide range data for crack tip parameters in two disc-type specimens under mixed mode loading
Disc-type specimens are among favorite test samples for determining mode I and mixed mode fracture toughness in brittle materials like rocks, brittle polymers, ceramics, etc. In this research, theExpand

Geometry and size effects on fracture trajectory in a limestone rock under mixed mode loading
The mixed mode I/II fracture initiation angle and the crack growth trajectory of a soft rock (Guiting limestone) were investigated experimentally and theoretically for two different shaped testExpand

An improved semi-circular bend specimen for investigating mixed mode brittle fracture
An edge cracked semi-circular specimen subjected to asymmetric three-point bend loading was suggested for investigating mixed mode fracture in brittle materials. Using finite element analysis, theExpand

Brittle failure of inclined key‐hole notches in isostatic graphite under in‐plane mixed mode loading
In the present contribution, the fracture behaviour of specimens made of isostatic graphite and weakened by inclined key-hole notches is investigated. Different loading mixities are consideredExpand

An over‐deterministic method for calculation of coefficients of crack tip asymptotic field from finite element analysis
An over-deterministic method has been employed for calculating the stress intensity factors (SIFs) as well as the coefficients of the higher-order terms in the Williams series expansions in crackedExpand

Determination of T-stress from finite element analysis for mode I and mixed mode I/II loading
The elastic T-stress has been recognised as a measure of constraint around the tip of a crack in contained yielding problems. A review of the literature indicates that most methods for obtaining TExpand

Effect of multi-walled carbon nanotube aspect ratio on mechanical and electrical properties of epoxy-based nanocomposites
Abstract The effects of the aspect ratio of multi-walled carbon nanotube (MWNT) on the mechanical and electrical properties of epoxy/MWNT nanocomposites were studied. It was found that the MWNTExpand

Mixed mode brittle fracture in epoxy/multi-walled carbon nanotube nanocomposites
Abstract The effects of multi-walled carbon nanotubes (MWNTs) on fracture behavior of epoxy under mixed mode I/II loading have been studied. A number of test specimens based on different contents ofExpand

Analysis of a new specimen for mixed mode fracture tests on brittle materials
Numerical and experimental studies were performed on a new fracture test configuration called the diagonally loaded square plate (DLSP) specimen. The mode I and mode II stress intensity factors wereExpand
