Let us get into the concepts of elasticity and plasticity and learn more about these two properties of matter. Plastic bodies do not show a tendency to recover to their original configuration when you remove the deforming forces. The phenomenon by virtue of which a substance exhibits a delay in recovering its original configuration if it had been subjected to a stress for a longer time, is called elastic fatigue. Elasticity:- The property of a body, by virtue of which body regains its original size and shape when the applied force is removed, is known as elasticity and the body is known as Elastic body. Haven’t you? Types of Forces.

Elasticity, ability of a deformed material body to return to its original shape and size when the forces causing the deformation are removed. Values of Ï lie between -1 and 0.5. Let us study more in-depth about the types of forces. In the fields of material science and physics, the plasticity of a solid substance can be defined as the ability of that solid to undergo deformation in its shape, which is a non-reversible change in the shape of the solid object and can be considered as the response of the object to an external force applied to it. Plasticity is the ability of a material to undergo permanent deformation. Your email address will not be published. Recall Hooke's law — first stated formally by Robert Hooke in The True Theory of Elasticity or Springiness(1676)… which can be translated literally into… or translated formally into… Most likely we'd replace the word "extension" with the symbol (∆x), "force" with the symbol (F), and "is directly proportional to" with an equals sign (=) and a constant of proportionality (k), then, to … Academic team of Entrancei prepared short notes and all important physics formula and bullet points of chapter Kinematics (class-11 Physics) . Required fields are marked *. As you know, Students need 11th class Physics book for exam preparation. Solid objects will deform when adequate loads are applied to them; if the material is elastic, the object will return to its initial shape and size after removal. Plastic bodies do not show a tendency to recover to their original configuration when you remove the deforming forces. Plasticity is the property of a body to lose its property of elasticity and acquire a permanent deformation on the removal of deforming force. These notes provide the students with the summary of the chapter, important points to remember and a detailed explanation of important concepts and derivations for better understanding. Generally, the material properties are specified in terms of yield stress and/or ultimate strength. Just the word “physics” is enough to make some people shudder with fear, but if you’ve just enrolled in your first college physics course, knowing what to expect can help ease any concern.
