How To Calculate Compressive Strength

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 …

Compressive Strength

The compressive strength of a material is its capacity to withstand loads that tend to reduce the object in size; in other words, how much pressure it takes to compress, flatten, or crush a meteorite. At the compressive strength limit, most meteorites will fracture, however, some, like the irons, could just suffer permanent deformation. This limit is governed by the mineralogical …
