deform

These threads should act just like the deformed ridges in normal rebar to create some grip between the concrete and steel.

And, the most common type of reinforcement used in concrete is deformed steel, more commonly known as rebar.

This is a much stiffer material that does not deform under load.

The anchor rod itself can fracture or deform.

The water disappears from the surface because it soaks into the extra space created when the sand was deformed.

The t-shirt material is stretchy, so when the vertical load is transferred into the reinforcement, it spreads out and deforms.
