The phrase "a tensile test sample" is correct and usable in written English.
It can be used in contexts related to materials science, engineering, or quality control when referring to a specimen used for tensile testing to measure material properties.
Example: "Before conducting the experiment, we prepared a tensile test sample to evaluate the material's strength and elasticity."
Alternatives: "a tensile specimen" or "a tensile testing specimen".
The elongation during each test was determined by optical measurement (video extensometer) of the displacement of two marker points placed along the waist of the tensile test sample.
As the superimposed hydrostatic pressure increases, the fracture surface of the hydroformed tube is also shifted from the P-type mode to C-type mode, a typical transition found experimentally for sheet tensile test samples deformed under superimposed hydrostatic pressure.
Tensile test samples were cut into a dog bone-shape from the sheet with the dimension of 40 mm (length) × 2 mm (width).
Tensile test samples having cross-section of 10×10 mm2 and a length of 30 mm were used for the experiments.
The fracture surfaces of the tensile test samples have been studied.
SEM and EDX analysis were used to study the presence of oxide bifilms and fracture surface of tensile test samples.
Fracture surfaces of tensile test samples with and without compost degradation or UV irradiation were analysed by using scanning electron microscopy (SEM).
Tensile test samples were prepared in the x-direction (sheet rolling direction) and the z-direction (in sheet plane direction that is transverse to the rolling direction), and compression test samples were prepared in the y-direction (sheet thickness direction).
The first two are measured in a tensile test, where a sample is loaded until it begins to undergo plastic strain (i.e., strain that is not recovered when the sample is unloaded).
Finally, the improvement of the prediction of strain maps was validated by performing a tensile test on another non-standard sample [2] which was not included in the identification protocol.
