Elasticity is the ability of materials to return to their original shape after a deforming (stretching, compressing, shearing, bending) force has been removed.
30 Οκτ 2024 · Elasticity, ability of a deformed material body to return to its original shape and size when the forces causing the deformation are removed. A body with this ability is said to behave (or respond) elastically. Most solid materials exhibit elastic behavior.
First, the object returns to its original shape when the force is removed—that is, the deformation is elastic for small deformations. Second, the size of the deformation is proportional to the force—that is, for small deformations, Hooke’s law is obeyed.
Explain the limit where a deformation of material is elastic. Describe the range where materials show plastic behavior. Analyze elasticity and plasticity on a stress-strain diagram. We referred to the proportionality constant between stress and strain as the elastic modulus.
INTRODUCTION TO ELASTICITY. David Roylance Department of Materials Science and Engineering Massachusetts Institute of Technology Cambridge, MA 02139 January 21, 2000. Introduction.
12.4 Elasticity and Plasticity. An object or material is elastic if it comes back to its original shape and size when the stress vanishes. In elastic deformations with stress values lower than the proportionality limit, stress is proportional to strain.
Elasticity: Elasticity is an inherent property by virtue of which a body undergoing a change in length, volume, or shape due to the application of external forces, tends to regain its original length, volume, or shape as soon as the external forces are withdrawn.
