F/A=Y delta L/L
Young's modulus, also known as the modulus of elasticity, is a measure of the stiffness of a solid material. It represents the ratio of stress (force per unit area) to strain (change in length per unit length) in a material when it is subjected to tension or compression.
Young's modulus is an important property of materials as it helps determine their strength and ability to deform under stress. It is also used to compare the elasticity of different materials and determine their suitability for various applications.
Young's modulus is calculated by dividing the stress by the strain in a material. The stress can be measured by applying a known force to a material and measuring the resulting strain using specialized equipment.
The unit of Young's modulus is typically measured in pascals (Pa) or newtons per square meter (N/m²). In the imperial system, it is measured in pounds-force per square inch (psi).
The main factors that affect Young's modulus include the type of material, its composition, and its microstructure. Temperature and strain rate can also have an impact on the modulus of elasticity of a material.
