Difference between the inelasticity and plasticity of metals

[hariharan venkatasu]

TL;DR

I am confused between inelasticity and plasticity of metals. Is there a clear cut distinction between these two properties? To me both seem to be same. None of the internet articles give clear and convincing answer . Could you please clarify the difference? Thank you.

It is felt that inelasticity can be used interchangeably.

Inelastic behavior contains plastic behavior, so they are often used interchangeably since plasticity is the major mechanism in metals. Inelastic behavior also contains other phenomena (fracture, void growth, recrystallization, …)

I did not understand what you mean by fracture ,void growth,recrystallization etc. Actually my question is whether is there a sharp difference between inelasticity and plasticity ?.

No.

Thank you very much for the answer

I was taught inelastic/plastic strain.
Inelastic strain occurs when a load ( below the tensile strength ) is removed from a metal and permanent internal stresses at the grain boundaries remains.
Plastic strain occurs when the materials tensile strength has been exceeded with a load. This type of strain is visible by eye. The material has been stretched.
You can research Young's Modulus of Elasticity for more info on a materials plastic limit.

Extremely thankful to you. Your answer is very clear

Further I want to know what is inelastic liquids which I came across a few days ago
