deformation of solids notes

These notes have the solution of numerical problems, solved exercise short questions and easy wording theory all in one PDF. Deformation of Solids • • • • • • It is possible to change the shape or size (or both) of an object through the application of external forces It is described as strain. (a) Solid:- It is the type of matter which has a definite shape and a definite volume. Revision Notes on Deformable Bodies and Elastic Deformation (Mechanical Properties of Solids):- Matter:- Anything which possesses mass and occupies space is called matter. For these materials Hooke's law is inapplicable. Explain how length of an object is determined. Plastic and elastic deformation, Heckel equation, Stress, Strain, What is thermal Stress? Notes – Deformation of Solids. Plastic bodies:- Bodies which do not show a tendency to recover their original configuration on the removal of deforming forces are called plastic bodies. Notes - Hooke's Law and Elastic Strain Energy. (ii) Tensile stress:- This stress results in increase in length per volume of the body.
