Answer:
Depending on the ductility of the sample, a more or less pronounced bulging occurs during the compression test. ... The onset of a crack in ductile materials or the sudden break in brittle specimens is characterized by ultimate compressive strength σcu.

Explanation:
During the compression test, ductile materials or metals like materials have a limit of elasticity in it. When compression or tension occurs on it then it starts to elongate in their elastic region or bulging in their elastic region.
After releasing the compression they back to its original formation. But if the compression level or the tension level became reached the highest level then this bulging formation of the ductile material will not change.
