MDT: Young's Modulus & Hooke's Law

What is Young's modulus?

Young's modulus, also known as the modulus of elasticity, is a measure of the stiffness or rigidity of a material.

How can Young's modulus be applied?

Young's modulus can be applied in material selection, structural design, material testing, finite element analysis, and analysing composite materials.

How does Young's modulus assist in material selection?

Young's modulus helps engineers determine the appropriate materials by comparing their stiffness or flexibility for specific applications.

What are the units of Young's modulus?

Young's modulus is measured in units of pressure, such as pascals (Pa) or gigapascals (GPa).

What is Hooke's Law?

Hooke's Law states that the force exerted by a spring or elastic material is directly proportional to the displacement or deformation produced by that force, as long as the elastic limit is not exceeded.

How can Hooke's Law be applied?

Hooke's Law can be applied in spring design, elasticity analysis, stress-strain calculations, material testing, and structural analysis.

How is Hooke's Law relevant in structural analysis?

Hooke's Law is utilized in structural analysis to estimate displacements and stresses within structures, aiding in design optimization and ensuring structural integrity.

How is Hooke's Law used in material testing?

Hooke's Law is employed during material testing to evaluate mechanical properties by measuring deformations under different loads and determining the material's elastic behaviour and Young's modulus.
