1. introduction
The universal testing machine (UTM), also known as a universal
tester, materials testing machine, materials test frame or
tensometer, is used to test the tensile strength and compressive
strength of materials. It can perform many standard tensile and
compression tests on materials, components and structures, in other
words, that it is versatile.

3. parameters can be measured
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):
Compression stress,
proof strength, non-proportional compression,
proof strength, total compression,
compressive yield strength,
upper compressive yield strength,
lower compressive yield strength,
compressive strength,
compressive modulus of elasticity
The universal testing machine can also make bending and flexural
test, shear test, peel test, high and low temperature test,
assurance loading test, wedge test, etc. if equipped with relative
test fixtures.
