HI!!!!
check out my answer....
The difference between the two is....
The plastic deformation will occur where pressures are relatively high and the strain rate relatively low. During plastic deformation, the materials flow and changes in shape will be permanent. While,
The elastic deformation will change shape in response to a stress, then snap back into it's original shape if the stress is removed. (in other words, the strain is recoverable)
IN short word...THE PLASTIC DEFORMATION ARE PERMANENT AND THE ELASTIC DEFORMATION WILL GO BACK TO ITS ORIGINAL SHAPE.

The Plastic Modulus, Zp, of a cross section is:
[A(y1+y2)]/2
The Elastic Section Modulus, Ze, is:
Zp/(shape factor).
Refer to http://books.Google.co.uk/books?id=N2WyMxutXK4C&pg=PA596&lpg=PA596&dq=zp+ze+shape+factore&source=web&ots=Cr8H3UVjca&sig=RlLHZLFWOYppLey6QEu962wyU0Y&hl=en#PPA596,M1

Elastic section modulus is used in general design. It is used to apply up to the yield point for common materials including most metals.
An elastic-perfectly plastic material is one which the material is linear elastic and as the load on material increases to yield point it's stress remains constant whilst strain increases
very elastic : some plastics can be streched up to 8 times its size

What is the opposite of elastic?
The opposite of elastic is inelastic, where a material cannot stretch and rebound. A material without this quality could be "inflexible" (rigid, stiff) or one that did not rebound, termed "plastic" (deformable).Elastic suggests that the material recovers its original shape after an applied load is removed. Plastic means that it doesn't recover its shape. Steel is an example of an elasticmaterial, when it is loaded within its capacity. It becomes plastic if it is overloaded. Concrete can be considered an elastic material only in compression.
What is difference between elastic and elastic plastic analysis how can one determine wether its elastic analysis or elastic plastic analysis in ANSYS?

What happens to strain when stress is increased in a material?
It also increases. It increases linearly with stress in the elastic range, then increass more rapidly once the material is plastic ( yielded).
What is the most aerodynamic material?
Generally the aerodynamic capability or aerodynamic strength of a material depends on its structure but not the material that it was made of. so even if we make a wing of some model plane using a steel like material and plastic like material with same design , both may show up same result (with in their elastic limits, until they break), so depending on elastic limits, we choose materials like aluminium and some alloys of it, since it is having lighter weight and higher elastic constants.
Material which exhibit the same elastic properties in all directions are called?
multicelastic body

What is the value of coefficient of restitution for the perfectly plastic body?
The coefficient of restitution for a perfectly plastic body is zero. This means that the body will not bounce off or rebound after impact, but will instead stick together with the other body.
What are the types of supply elasticity?
Types of elasticity of supply1) Perfectly elastic supply2) Relative elastic supply3) Unitary elastic supply4) Relatively in elastic supply5) Perfectly in elastic supply
When demand is perfectly elastic what happens to marginal revenue?
When Demand is perfectly elastic, Marginal Revenue is identical with price.
Demand and its types?
Perfectly inelastic demand, perfectly elastic demand, elastic demand, inelastic demand etc.
What is the mathematical definition of perfectly elastic demand?
If ep = dQ/dP.P/Q = infinity, the demand is perfectly elastic.
What is the effect of springback concept on plastic deformation?
Springback means Recovered elastic strain on material after the load is removed.
What is the difference between elastic deformation and ductile deformation?
Elastic deformation is reversible and occurs when a material is stretched but returns to its original shape once the stress is removed. Ductile deformation, on the other hand, is permanent and occurs when a material is stretched beyond its elastic limit, resulting in plastic deformation that changes the material's shape permanently.
If the elasticity equals 0 is demand perfectly elastic or perfectly inelastic?
it is perfectly inelastic
The distance a material can stretch without tearing is?
known as the elastic limit or elongation at break. It varies depending on the type of material and its tensile properties, such as strength and ductility. Once a material reaches its elastic limit, it will undergo plastic deformation and potentially tear if stretched further.
