Tensile testing subjects a material sample to controlled tension until failure to determine properties like ultimate tensile strength and elongation. The test uses a universal testing machine to apply tension to a standardized tensile specimen, measuring properties like modulus of elasticity, yield stress, and fracture stress. The test procedure involves securing the specimen in the machine and applying tension until failure while recording the stress-strain curve.

2. TENSILE-TESTING
Tensile testing, also known as tension testing, is a fundamental
materials science and engineering test in which a sample is
subjected to a controlled tension until failure. Properties that
are directly measured via a tensile test are ultimate tensile
strength, breaking strength, maximum elongation and
reduction in area.

3. Aims of Test
The aims of test are to find the following:
1. Modules of elasticity
2. Elastic stress
3. Yield stress
4. Yield strain
5. Ultimate tensile stress
6. Fracture stress
7. Total strain
8. Toughness
9. resilience

4. Equipment and Material
1- Universal Testing Machine.
The most common testing machine used in
tensile testing is the universal testing
machine. This type of machine has
two crossheads; one is adjusted for the
length of the specimen and the other is
driven to apply tension to the test specimen.
There are two types: hydraulic powered
and electromagnetically powered machines.

2- Tensile Specimen
The preparation of test specimens
depends on the purposes of testing
and on the governing test
method or specification. A tensile
specimens is usually a standardized
sample cross-section. It has two
shoulders and a gage (section) in
between.
