Triaxial stresses caused by notches

British Journal of Applied Physics, 1954
The purpose of the work described was to give metallurgists a guide on means of suppressing plastic deformation in ductile materials, so as to provide a test for brittleness. Stress analyses were made on round bars with circumferential notches by the photoelastic frozen stress method and mechanical tests on steel test pieces provided additional ...

Stress Triaxiality in Damage Models

2017
High strain rate of loading combined with multiaxial effects are important factors, which we need to consider in understanding the response of structures subjected to hard-body impact, blast, and detonation. Better design and load mitigation schemes against these factors can be developed based on the simulations that should be more reliable in ...

Stresses and Strains in Triaxial Specimens

1965
Stresses and strains were measured in triaxial specimens of dry sand under slow and dynamic rates of loading. Stress gages employing piezoelectric transducers were found to be sensitive to initial placement conditions, changes in the modulus-of-deformation of the surrounding soil, and lateral deformations of triaxial specimens approaching failure ...

Improvements to a Stress-Path Triaxial Cell

Geotechnical Testing Journal, 1995
Abstract Stress-path triaxial cells are presently used all over the world. Accurate use of this type of apparatus allows an investigation into the mechanical behavior of soils with regard to a wide range of stress and strain. A correct evaluation of small-strain stiffness requires an accurate definition of the compliance curve of the ...

Concrete under triaxial stress

Magazine of Concrete Research, 1961
Summary This paper describes the results of the first series of experiments carried out to study the effect of pore-water pressure on the ultimate strength of concrete subject to triaxial stresses. These tests have demonstrated that saturated concrete behaves like a material which does not possess the property of internal friction, when tested ...

Stress Conditions in Triaxial Compression

Transactions of the American Society of Civil Engineers, 1960
Investigation of stresses and deformations occurring in test specimen, during triaxial compression test, used to determine shearing strength of soil; influence of end restraint on cylindrical test specimens exerted by stiff loading plates with any degree of roughness, is considered by introduction of simplified roughness function; numerical solutions ...

A model for concrete subjected to triaxial stresses

Cement and Concrete Research, 1975
Abstract A model of concrete consisting of cylindrical pieces of aggregates in a matrix of cement paste was analyzed by the plane-stress finite element method. The three-dimensional case was reduced to a two-dimensional one by restricting the multiaxial stresses to the cylindrical triaxial state of stress.

Uncertainties in Triaxial Residual Stress Measurements

Materials Science Forum, 2011
Residual stress measurement techniques using mechanical strain relaxation depend on a number of physical quantities and are therefore sensitive to errors associated with the measured data. The resulting stress uncertainties can easily become significant and compromise the usefulness of the results or lead to misinterpretation of the behaviour of the ...

Thermal Residual Stresses and Triaxiality Measures

PAMM, 2010
AbstractHigh performance ceramics have found their way into many highly challenging engineering tasks. For example silicon nitride is one of the best choices, if a material for demanding applications like metal forming and cutting is required. Due to the brittle nature of these hard and strong materials it is useful to know about thermal residual ...

Triaxial Stress-Strain Relationship for Concrete

Journal of the Engineering Mechanics Division, 1977
A triaxial constitutive law and a failure criterion for concrete under short-term monotonic loading are derived from the analysis of available experimental data. Their representation through the octahedral normal and shear components of stresses and strains show that the deformational behavior of concrete can be described through simple analytical ...
