### How to calculate compressive strength eHow .

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 Or Crushing Strength. Compression across the grain is very closely related to hardness and transverse shear. There are two ways in which wood is subjected to stress of this kind, namely, (1) with the load acting over the entire area of the specimen, and (2) with a load concentrated over a portion of the area.

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.

Estimating compressive strength. General rock failure criterion can be reduced to a few parameters dependent on lithology (m) and the uniaxial compressive strength (C 0). Lithology is commonly derived during log analysis, so m may be estimated (Table 1). What is needed still is an initial measure of rock strength provided by C 0.
