Abstract

A crucial tool for describing the mechanical properties of materials, including concrete, is the stress-strain curve. To comprehend material reactions, design structures, and foresee failure modes, it gives important information regarding the connection between applied stress and generated strain. This abstract emphasizes the significance, typical shapes, and important characteristics of concrete-specific stress-strain curves. Concrete stress-strain curves show the stress that is applied to the material and the related strain. Strain is the term for the material's distortion or lengthening brought on by applied stress. Stress-strain curves for concrete display nonlinear behavior, with multiple stages that capture various mechanical events. Concrete's stress-strain curve often starts linear, reflecting the material's elastic properties. When a load is removed, the material recovers its previous shape because the applied tension during this phase causes elastic deformation. Hooke's law, which states that stress is directly proportional to strain within the elastic limit, governs the connection between stress and strain. The slope of this linear part, also referred to as Young's modulus or modulus of elasticity, indicates the stiffness of the concrete.
