As per name the tensile word consisting different types of loading as ,
1)
Tensile Loading.
2)
Compressive Loading.
3)
Shear Loading.
4)
Torque Loading.
5)
Bending Moment Loading
Tensile
test is also known as tension test. The tensile test is one of the most common
mechanical testing is used to measure tensile strength and ductility of the
material. In tensile test the material is pulled and measure the stress.
Tensile testing is related to mechanical behavior of the material and in this
testing checking the response of the specimen during loading.
By tensile testing we can measure the
yield strength, modulus of elasticity, reduction in areas, elongation till
fracture and ultimate tensile strength of the specimen. The measurement of
tensile testing of the material is very important for find out maximum
force absorbed by the material before change its molecular structure. With help
of tensile testing we can plotted the data on graph on stress-strain curve
which gives results of how the material reacted to forces being applied.
The Tensile Testing Specimen as shown below,
PIC.01
Types of Tensile Tastings:
1) Adhesion/Bond
strength Testing.
2) Crimp
joint pull-off Joint Testing.
3) Peel
Testing.
4) Tear
Resistance Testing.
Acceptance criteria for tensile testing is as per ASME SECTION IX The test specimens should be
break less than minimum specified tensile strength in weld or
weld interface. However, if it breaks in the area out of weld or weld interface
will be acceptable 5% below the minimum specified tensile strength.
Advantages:
1 1) Tensile
testing is the destructive testing in which the sample is made in standard size
2 2) The
tensile test is done at constant strain rate and constant temperature
3 3) Quick
way to determine the problem in the material
4 4) We
get poisons ration which is helpful for FEA (finite element analysis)
Disadvantages:
1 1) Tensile
testing does not provide the information of materials at different temperatures.
2 2) At
different strain rates the straight of the material can’t find by tensile
method.
3 3) Restricted
to ductile materials.
4 4) Tensile Testing is destructive testing so material gets wasted every
time after testing.
