Question

a stress-strain relationship that exhibits behavior that is elastic and perfectly plastic is characteristic of what types of materials?

Answer 1

Composite of two materials.

Step-by-step explanation:

Any material that exhibits behavior that is elastic and perfectly plastic is a characteristic of a composite material. This represents a two element composite material exhibiting dual properties that is elastic and perfectly plastic.

The material is subjected to tensile loading and assumed to be isotropic obeying the Tresca yield criterion.
