Compressive stress arises from forces that attempt to condense or shrink the material or wire (squeezing as opposed to pulling). A critical compressive stress for HTS wire is the amount of compressive stress that can be applied to the wire before the critical current is reduced below a specified level (such as 95% Ic retention).

Stress that involves the squeezing or compression of a material.

A stress which pushes two parts of a body together.

A stress or pressure that tends to push or clamp objects together. The state of stress found in the rock mass before mining occurs. Tends to hold the rock mass together.

A stress that causes an elastic body to deform (shorten) in the direction of the applied load. Contrast with tensile stress.

Compressive stress is the stress applied to materials resulting in their compaction (decrease of volume). When a material is subjected to compressive stress then this material is under compression. Usually compressive stress applied to bars, columns, etc. leads to shortening.
