tensile

But, the problem with joints is that they have no tensile strength, and so no ability to transfer tensile stress.

The steel rebar and fibers team up to resist tensile stresses in the beams.

And the bottom of the beam experiences tensile stress.

These cracks form because steel stretches a little bit as it takes up the tensile stress in the concrete.

Rock, on the other hand, behaves a little bit differently in that it does have some tensile strength.
