NettetLinear elastic deformation is governed by Hooke's law, which states: Where is the applied stress, is a material constant called Young's modulus or elastic modulus, and ε is the resulting strain. This relationship only applies in the elastic range and indicates that the slope of the stress vs. strain curve can be used to find Young's modulus ( ).

Nettet12. sep. 2024 · In the linear limit of low stress values, the general relation between stress and strain is stress = (elastic modulus) × strain. As we can see from dimensional analysis of this relation, the elastic modulus has the same physical unit as stress because strain is … Nettet9. sep. 2024 · A linear elastic material is a mathematical model used to analyze the deformation of solid bodies. It is useful to compute the relation between the forces applied on the object and the corresponding change in shape. In other terms, it relates the stresses and the strains in the material.

Nettet8.4 Elastic Perfectly Plastic Materials Once yield occurs, a material will deform plastically. Predicting and modelling this plastic deformation is the topic of this section.
