Elastic modulus of Thermal Analysis

Modul of elasticity | Young’s modulus

The modulus of elasticity is a crucial material parameter frequently employed in the static analysis of components. When a solid body is subjected to a tensile force, it undergoes a change in length. This action induces internal forces within the body, which counteract the length change once the external pulling force is removed. When the magnitude of the tensile force remains below a material-specific threshold, the force and change in length exhibit a proportional relationship, a principle known as Hooke’s Law.

For the sake of comparability, the tensile force is normalized to the cross-sectional area of the unloaded component. The ratio of force to cross-section is defined as tension.

Similarly, the change in length is related to the length of the unloaded component. The quotient of the length increase and the original length yields the elongation.

What is the Young´s modulus?

Young’s modulus, also known as the Young modulus, represents a mechanical property quantifying the stiffness of a solid material. It delineates the correlation between stress (force per unit area) and strain (proportional deformation) in the linear elasticity range of uniaxial deformation. The unit of measurement for Young’s modulus is N/m², which is mathematically consistent with the Pascal, the unit used for pressure. In certain contexts, tables may express the modulus of elasticity using the unit Pascal.
