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.

RossThe Plastic Modulus, Zp, of a cross section is:
[A(y1+y2)]/2
The Elastic Section Modulus, Ze, is:
Zp/(shape factor).

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?
your face for gods sake
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.
Is plastic a modern textile material?
no
