thermodynamics of plasticity

Thermodynamics of plasticity studies how materials deform permanently when subjected to stress, such as stretching or compressing. It combines principles of thermodynamics, which deal with energy and heat, with the understanding of material behavior. When a material reaches its yield point, it undergoes plastic deformation, meaning it changes shape without returning to its original form. This process involves energy flowing into the material, causing changes at the atomic level. Understanding these concepts is crucial in fields like engineering and manufacturing, as it helps predict how materials will perform under different conditions and ensures safety and reliability in products.
