Testing the ability of different types of materials
under tensile stress is one of the major things which are done to ascertain the
properties of the materials that are used in structural applications. The force
per unit area i.e. Mpa or psi is required
to provide stress to the material is ultimately known as the tensile strength
of the material. The rate at which a sample is pulled apart from both the ends with
the speed of 0.2 to 20 inches per minute is known as the Ultimate Tensile Strength or Tensile
Strength at Break. The test is performed appropriately with the help of
testing machine known as a tensile
testing machine. The machines are
designed as per the standard ISO 527 & ASTM D638 that helps in offering
good and precise test results in the material selection process. The tensile
test using high-quality of the tensile
testing machine can be performed on various materials such as polymer films,
elastomers, plastics, rubbers, textile, and many
more. The instrument helps to calculate various properties of the material such
as tensile elongation, a tensile modulus
of elasticity, and many more.
Tensile Elongation
The elongation of engineered material is
calculated with the percentage increase in length before it breaks under a high amount of tension. The elongation values
are common for elastomers and packaging polyolefin, packaging films and rigid
plastic materials. The material with high tensile strength and high elongation
strength means very tough material with high strength.
All the values can be tested using tensile testing machine. Presto Stantest offers a wide array of testing instruments
that are used by the manufacturers for a large
number of applications. To check the entire range of machines, visit:
