Theory of failure is a concept used in engineering to predict the failure of materials under different loading conditions.

• Theory of failure helps engineers understand how materials will behave under stress and strain.

• Different theories of failure include maximum normal stress theory, maximum shear stress theory, and maximum strain energy theory.

• Finite Element Method (FEM) is a numerical technique used to analyze stress...read more

The SS curve is a stress-strain curve used to analyze the behavior of a material under stress.

• The SS curve, also known as the stress-strain curve, shows the relationship between stress (force applied per unit area) and strain (deformation) of a material.

• It typically consists of three main regions: elastic deformation, plastic deformation, and fracture.

• The elastic region is where the material deforms elastically and ret...read more
