... displacement-based data indicate an extraordinarily large elongation. We will use the Young’s modulus to provide an example of the disparity in measured properties. For each curve, we select a couple of points for the calculations. Extensometer: (105 MPa, 0.00068) and (396 MPa, 0.00256) E = rise run...

... During a tensile test, the force applied to the test piece and the length of elongation of the test piece are measured simultaneously. The applied force is measured by the test machine or by accessory force measuring devices. The amount of stretching or extension can be measured with an extensometer...

... the very best experimental conditions, the coefficient of variation for the modulus data derivable from tensile tests can be 0.03 or lower, but more typically it is 0.10 ( Ref 7 ). If the strain is derived from the relative movement of the clamps rather than from an extensometer, the error...

.... This advantage, however, was soon lost once low-cycle fatigue testing came into its own with the development of reliable extensometers, closed-loop servocontrol systems, bending-free alignment fixtures, and backlash-free grips that permitted reliable axial loading into compression as well as tension. Once...

.... However, total strain range is relatively easy to measure using extensometers, resistance strain gages, or numerous other methods. The second goal, therefore, was to express life in terms of total strain range consisting of both plastic and elastic components. Examining the problem in retrospect...

In most cases, tests were made of several lots of material of each alloy and temper, and the results analyzed and the averages normalized to the room...

... Testing was conducted in either of three ways. Force was varied from zero to a positive maximum ( Fig. 12.23 ), zero to a negative maximum ( Fig. 12.24 ), or completely reversed ( Fig. 12.25 ). Strain was measured with an extensometer allowing the display of hysteresis loops. Stress was calculated based...
