Is there an indent when standing on a solid surface?

[Acadeus]

Does anyone know for sure that when standing in a single spot (for a better idea we will say on a block of steel) that there is a microscopic indent (not permanent) on the steel block. For more elaboration I see it as the same aspect as walking on a plank of wood and it will bend due to your weight but because the stronger density of the steel block it would be less evident.

“Many materials display linear elastic behavior, defined by a linear stress-strain relationship, as shown in the figure up to point 2, in which deformations are completely recoverable upon removal of the load; that is, a specimen loaded elastically in tension will elongate, but will return to its original shape and size when unloaded.”

Yes there will be an indent. Every material when subjected to a stress will elongate or compress, although as you said if it's just you standing on a steel block then this deformation will be minuscule.

Thank you guys

Thank you guys

The fact that sound waves can be transmitted through 'solids' is proof that there is some deformation as a result of an applied force. 'Everything' has a Young's modulus.
