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

Composite of two materials.

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.

if you are asking how much they can go over the 1500 limit it would be safetly within the 2310 and 2600.mg

just put in mind that others aren't perfect. we all have problems that we feel makes us low of the low. but know that you are special and unique, that is what makes you out of this world : ). you might think and feel that others judge you, but mostly other people are scared if people judge them. just be happy, spend time with family, smile because that is the greatest medicine. a happy life. hope this : ))
