Stress-strain diagrams are formed from axial tension, shear loading conditions and compression. Tension specimens generally have a small region in the middle which is called as ‘gage length’. Compression samples are thicker and shorter than tension samples with no cross-sectional differences. We can calculate normal stress by dividing the applied force by the cross-sectional area of the specimen. The normal strain is calculated by dividing the change in gage length by its original value number.

There are many Stress-strain diagrams for engineering materials notes for GATE pdfs and Stress-strain diagrams for engineering materials study material for GATE ME online that you can refer to for stress-strain diagrams. Questions on Stress-strain diagrams are usually asked in the GATE and other engineering entrance exams.

Important Topics in Stress-Strain Diagrams for GATE ME

Topic	Explanation
Proportional Limit (Hooke’'s Law)	The origin, which is referred to as O, is called a proportional limit. In 1678, Robert Hooke noticed that the stress-strain curve is a straight line, and since then, it is called Hooke’'s Law, which states that stress is directly proportional to strain. It is also denoted as: σ∝εσ∝ε or σ=kεσ=kε k is the constant proportional limit known as modulus of elasticity E or popularly as Young's Modulus. The slope of the stress-strain diagram is equal to Young’s Modulus. Hence: σ=Eε You will find online many stress-strain diagrams for engineering materials GATE questions and answers pdfs, stress-strain diagrams for engineering materials MCQ questions regarding Hooke’s Law and its application online.
Elastic Limit	It is a limit beyond which any material will no longer revert to its original shape after the load is reduced or removed. In other words, the maximum stress is created so that there is no scope for deformation when the load is completely removed.
Modulus of Toughness	The work is applied in a unit volume of a material when the force is increased from O to R. It is calculated by seeing the area under the stress-strain curve. There are many stress-strain diagrams for engineering materials notes for ME and stress-strain diagrams for engineering materials MCQ pdfs that you can refer to exploring elastic limit lab experiments and study material.
