What are the differences between elastic stress and thermal stress?

1.	What are the differences between elastic stress and thermal stress?
Answer» Thermal stress is mechanical stress that created by CHANGE in temperature of material.Thermal stress is useful in creating many electronic devices e.g air conditioner.Elastic stress is applied to POLYMERS like rubber, when stress applied its length volume and AREA changes ,applied stress is REMOVED (within elastic LIMIT) the body come back to its original position e.g spring , rubber" Steel is more elastic"
