The relationship between stress and strain is crucial for understanding material behavior under external loads. This chapter introduces the stress-strain relation and focuses on formulating the linear stress-strain relationship and its implications in solid mechanics. The importance of additional equations, known as constitutive relations, is emphasized to solve equilibrium equations for deformed bodies.
