Question

Differential stress changes the size, but not the shape of an object. T/F?

Answer 1

When the size getting changed obviously the shape will also change unless you cover the outer portion to have only linear expansions.

Answer 2

"The condition in which a material experiences a push or pull in one direction of a greater magnitude than the push or pull in another direction; in some cases, differential stress can result in shearing"
