PROPERTIES DETERMINE BY TENSILE TEST

A tensile test applies tensile force to material and measures specimen's response to the stress.
It determines following properties of specimen.

1.Elastic limit

2.Yeild strength
3.Ultimate tensile strength
4.Fracture strength
5.Resilience
6.Toughness

1. Elastic limit
  • When a material subjected to tensile load a material starts deformation or extension but when the load is removed, the deformation is completely recovered. This limit is termed as elastic limit.
2. Yeild strength
  • When a material subjected to tensile stress and stress beyond the elastic limit plastic deformation occurs and this plastic deformation are not regain its original shape. A material on this point is called yeild strength.
3. Ultimate tensile strength
  • It is a maximum stress bearing capacity of material when it is subjected to loading. It is a strength prior to material start occuring necking.
4. Fracture strength
  • Fracture is a separation of  a material and fracture strength is the stress just prior to specimen gets failure or getting a fracture. This point at which stress is recorded and it is known as fracture strength.
5. Resilience
  • Resilience is the ability of material to absorb energy at its elastic deformation and on the removal of load this absorbed energy is used as to regain material's original position or shape.
  • this is shown in flex material like rubber.
6. Toughness
  • Toughness is the ability of material to absorb energy and plastically deform without being fracturing.
  • Material toughness is the amount of energy per unit volume that material can absorb before rupturing.
