The stress that results from the shortening in one dimension  of an elastic body due to oppositely directed collinear forces tending to crush it







  • Compressive strength involves testing and calculating how well a given specimen, product or material can survive compressive stress. Unlike tension, which expands or pulls, compression means a specimen, product or material is shortened or pressed down.


  • Compressive strength of a material is the point at which the material fails. Calculating compressive strength involves testing to find this failure point and using the data from the test to feed the calculation.


  • The final compressive strength number is in pounds-force per square inch, or psi.




Calculate the compressive strength using the formula

                                                 S = P/A,

where S is the compressive strength, P is the maximum load applied to the specimen and A is the area.
