When a specimen of material is loaded in such a way that it extends it is said to be in tension. On the other hand, if the material compresses and shortens it is said to be in compression. On an atomic level, the molecules or atoms are forced apart when in tension whereas in compression they are forced together. Since atoms in solids always try to find an equilibrium position, and distance between other atoms, forces arise throughout the entire material which oppose both tension or compression. The phenomena prevailing on an atomic level are therefore similar.

Crushing strength is about compression, and elasticity is about bending perpendicular to the grain, so not really what I want either. I’m building a guitar and want to make a top from Sitka Spruce and another top from carbon fiber sheet, and compare them.

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 …

The one-dimensional compression yield stress was related to the particle size and this was also related to the single particle crushing strength. The decrease of the vertical yield stress with increasing initial void ratio can be explained by the increase in the particle characteristic stress as the void ratio increased and a corresponding decrease in co-ordination number.

I think that you can measure compression strength using ultrasonic method. You can control this method using Schmidt Hammer. Usually the difference between these two methods is less than 8%.

The electronic unit drives the compression process and provides to display and to print the crushing strength values and to calculated statistic data. The available statistics are: minimum and maximum value, number of tests with values under different thresholds, mean value, standard deviation and variation coefficient.

So, compressive strength is the highest load per unit area borne by the stone without giving in. A higher compressive strength between1,800 psi (12.45 MPa) and 19,000 psi (131 MPa) means the stone can endure an upper crushing load. Dry or wet conditions as per load determine the compressive strength of the stone. Bending strength test

loblolly pine, while maximum crushing strength parallel to the grain and modulus of elasticity were about 6 percent lower and compression perpendicular to the grain was 16 percent lower. In flexure, only 5.1 percent of the total lumber sample was below the presently assigned bending

Compressive (Crushing) Strength. Amount of compressive stress at the onset of failure. The definition of failure tends to vary with material type. As with tensile tests, the terms ultimate and yield can be used. However, ductile materials do not break during compressive testing, and therefore have no ultimate compressive strength.
