Various new tensile testing machines have been developed to obtain accurate stress-strain (S-S) relationships at high strain rates. Six types of these machines and one conventional machine were used to obtain S-S relationships at various strain rates from 10{sup}(-3) to 10{sup}3/s for IF...

The line0Ein the Stress-Strain curve indicates the range ofelastic deformation– removal of the load at any point of this part of the curve results in return of the specimen length to its original value. The elastic behavior is characterized by theelasticity limit(stress value at the pointE):...

Testing machines need to have analog and/or digital option of collecting and storing data on the tested values (load, stress as a function of time, displacement or deformation) (Carlssonet al., 2000). A digital record makes the data analysis easier. Force-elongation and stress-strain are com...
At a minimum, display the stress-strain curve and have displays for the load and strain. Select an appropriate testing procedure within the software that is compatible with the ASTM E8 testing protocol. Note the strain rate being used and whether two rates, one for the elastic and one for ...
In order to obtain the tensile stress-strain curve of steel fiber reinforced reactive powder concrete( RPC),axial tensile tests on reactive powder concrete were completed using a self-designed equipment. The complete tensile stress-strain curve of RPC with different volume fraction of steel fiber( ...
In order to significantly extend the limit of the measurable strain range to obtain true stress-strain curves of materials using tensile testing, digital image correlation is used to measure local strains. In this study, a method to measure reliable true stress-strain curves in a wide range of...
The stress–strain curve. The various properties are defined as follows: (a) Stress: The load applied to a nonwoven specimen, ever increasing, as the tension increases. It is measured in force per unit width of specimen. In SI units this is often kN/m and sometimes kN/15 mm. In U....
