WebThus, different conditions and methods are used to study the stress-strain behavior of the concrete. The above graph explanation is done considering the uniform increase in stress over concrete. However, due to heterogeneous property, it is also subjected to a uniform increase in strain to observe corresponding behaviors of stress. ... WebIn elastic deformations with stress values lower than the proportionality limit, stress is proportional to strain. When stress goes beyond the proportionality limit, the deformation is still elastic but nonlinear up to the elasticity limit. An object or material has plastic behavior when stress is larger than the elastic limit.
