SMS Group Engineer Interview Questions and Answers

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

Different bolt grades are used for various applications based on their strength and durability.

• Bolt grades are typically indicated by numbers or letters, such as Grade 2, Grade 5, Grade 8, etc.

• Higher grade bolts have higher strength and are used in applications where greater load-bearing capacity is required.

• Common grades include Grade 2, Grade 5, Grade 8, and stainless steel bolts.

• Each grade has specific properties an...read more
