In structural steel design, which phase follows the elastic region in stress-strain behavior?
Understand the Problem
The question is asking about the phases of stress-strain behavior in structural steel design, specifically what comes after the elastic region. The options provided suggest various phases that can occur in the material's behavior under stress.
Answer
Plastic region or phase.
The final answer is the plastic region or plastic phase.
Answer for screen readers
The final answer is the plastic region or plastic phase.
More Information
In structural steel design, after the elastic region, the material enters the plastic region. In this phase, the material undergoes permanent deformation and does not return to its original shape when the load is removed.
