Theory of Pure Bending
Theory of Pure Bending Loading restrictions: As we are aware of the fact internal reactions developed on any cross-section of a beam may consists of a resultant normal force, a…
Strain Energy
Strain Energy Strain Energy of the member is defined as the internal work done in defoming the body by the action of externally applied forces. This energy in elastic bodies…

Tensile Test diagram for Ductile and Brittle Materials Measures of Ductility (Elongation and Reduction of Area) The ductility of a material is a measure of the extent to which a…
Normal and Shear Stresses
Normal Stress Stress is defined as the strength of a material per unit area or unit strength. It is the force on a member divided by area, which carries the…
Understanding of Simple Stress and Strain
Stress The term stress (s) is used to express the loading in terms of force applied to a certain cross-sectional area of an object. From the perspective of loading, stress…
