Typical flow plasticity theories for unidirectional loading (for small deformation perfect plasticity or hardening plasticity) are developed on the basis of the following requirements: 1. The material has a linear elastic range. 2. The material has an elastic limit defined as the stress at which plastic deformation first takes place, i.e., . Web9 jun. 2024 · Once yield stress is reached, the elasto-plastic law covers the relationship between stress increment and now a combination of elastic and plastic strain. This post is dealing with a specimen modeled with an isotropic material, which means that the material behaves the same way in tension and compression, and in all directions.
