The objects which after deformation gets in their original shape are called as Elastic objects and the property is known as Elasticity.
Those which after deformation do not able to gain their original shape is known as Plastic objects and the property is known as plasticity..
Stress is defined as the restoring force acting per unit area. For eg if you push a rubber block against a wall, the restoring force will act on the body against the Applied force. Also stress characterise the strength of the force causing the deformation.
Stress are of following types
Tensile stress which is defined as tensile force per unit area
Bulk stress which is defined as the fluid force per unit area
Shear stress which is defined as force applied tangentially to a surface.
