👉 Elastance is a concept in engineering that describes how well an object or material resists deformation under stress. It is also known as stiffness, and it is primarily used to describe how a material behaves when subjected to forces. Elasticity can be classified into two types: linear elasticity and nonlinear elasticity. Linear elasticity refers to the behavior of materials under simple, uniform loading conditions, such as those that occur in everyday life. This type of elasticity is characterized by the stress-strain relationship, which states
