Now, if the body returns to its original shape, the body is said to be elastic in nature, and this property is called as 'elasticity'. On the other hand, if the body does to regain its original shape, the body displays plastic nature, and this property is

Modulus of elasticity - and Ultimate Tensile and Yield Strength for steel, glass, wood and other common materials. the amount of stress (Yield point) that a material can undergo before moving from elastic deformation into plastic deformation.

E is Young's modulus or modulus of elasticity. The yield stress measures the resistance to plastic deformation. The reason for plastic deformation, in normal materials, is not that the atomic bond is stretched beyond repair, but the motion of

Price elasticity of demand is a measure of the change in the quantity demanded or purchased of a product in relation to its price change.

In physics and materials science, plasticity describes the deformation of a (solid) material undergoing non-reversible changes of shape in response to applied forces. For example, a solid piece of metal being bent or pounded into a new shape displays plasticity as permanent changes occur within the material itself. In engineering, the transition from elastic behavior to plastic behavior is called yield. . transformations, deform in ways that are not well described by the classic theories of plasticity and elasticity.

14 Jun 2011 Policy makers in many countries have perceived plastic-bag litter as a problem, and have used a variety of regulatory tools to address it. South Africa's current legislation on plastic-bags came into effect on 7 May 2003.
The opposite of elasticity is plasticity; when something is stretched, and it stays stretched, the material is said to be plastic. When energy goes into changing the shape of some material and it stays changed, that is said to be plastic deformation.
In physics, elasticity (from Greek ?λαστ?? "ductible") is the ability of a body to resist a distorting influence and to return to its original size and For even higher stresses, materials exhibit plastic behavior, that is, they deform irreversibly and do not return to their original shape after stress is no longer applied. For rubber-like
The more difficult it is to stretch, the more elastic a material is called to be because elasticity is defined by the ratio stress to . The confusion comes out because steel is indeed more elastic then rubber, but it also reaches plastic deformation
plastic behaviour is characterised by there being permanent (non-reversible) deformations. In terms of molecules held together with springs (the bonds) in plastic deformation the springs are broken and the bonds then might
Tensile property tests for plastics are illustrated and give average values of ultimate tensile strength, elongation, and The figure below, from Quadrant Engineering plastic Products, shows the test geometry. Tensile Modulus of elasticity.
