The compressive strength gives the stress that is needed to destroy the sample by crushing. There is a complication though. If the material is brittle, such as concrete then the point of failure is clear. The sample suddenly fractures, frequently quite explosively as the stored energy is released.

This force is nearly independent of velocity. For realistic crushing strengths, the maximum force is significantly lower than in our previous static analysis of ridge ride-up without crushing. With consideration of lengthwise flexural failure, the dynamic ride-up model is applied to the development of design loads for a 40-deg conical structure.

[PDF] - Compressive strength - Wikipedia
Compressive strength or compression strength is the capacity of a material or structure to withstand loads tending to reduce size, as opposed to tensile strength, which withstands loads tending to elongate. In other words, compressive strength resists compression (being pushed together), whereas tensile strength resists tension (being pulled ...
