For tensile test, the universal testing machine can measure following parameters according to different materials (not limit to the following):
Elongation: increase in the original gauge length at any moment during the test
Percentage elongation: elongation expressed as a percentage of the original gauge length
Percentage permanent elongation: increase in the original gauge length of a test piece after removal of a specified stress, expressed as a percentage of the original gauge length
Percentage elongation after fracture: permanent elongation of the gauge length after fracture, expressed as a percentage of the original gauge length
Extensometer gauge length: initial extensometer gauge length used for measurement of extension by means of an extensometer
Extension: increase in the extensometer gauge length at any moment during the test
Percentage extension/ strain: extension expressed as a percentage of the extensometer gauge length
Percentage permanent extension: increase in the extensometer gauge length, after removal of a specified stress from the test piece, expressed as a percentage of the extensometer gauge length
Percentage yield point extension: in discontinuous yielding materials, the extension between the start of the yielding and the start of uniform work-hardening, expressed as a percentage of the extensometer of the extensometer gauge length
Percentage total extension at maximum force: total extension (elastic extension plus plastic extension) at maximum force, expressed as a percentage of the extensometer gauge length
Percentage plastic extension at maximum force: plastic extension at maximum force, expressed as a percentage of the extensometer gauge length
Percentage total extension at fracture: total extension (elastic extension plus plastic extension) at the moment of fracture, expressed as a percentage of the extensometer gauge length
Maximum tensile force: highest force that the test piece withstands during the test
Stress: at any moment during the test, force divided by the original cross-sectional area of the test piece
Tensile strength: stress corresponding to the maximum force
Yield strength: when metallic material exhibits a yield phenomenon, stress corresponding to the point reached during the test at which plastic deformation occurs without any increase in the force
Upper yield strength: maximum value of stress prior to the first decrease in the force
Lower yield strength: lowest value of stress during plastic yielding, ignoring any initial transient effects
Proof strength/ plastic extension: stress at which the plastic extension is equal to a specified percentage of he extensometer gauge length
Proof strength, total extension: stress at which total extension (elastic extension plus plastic extension) is equal to a specified percentage of the extensometer gauge length
Permanent set strength: stress at which, after removal of force, a specified permanent elongation or extension, expressed respectively as a percentage of original gauge length, or extensometer gauge length, has not been exceeded.
Modulus of elasticity: quotient of change of stress and change of percentage extension in the range of evaluation, multiplied by 100%
For compression test, this universal testing machine can measure following (not limit to the following):
proof strength, non-proportional compression,
proof strength, total compression,
compressive yield strength,
