Crushing of Plywood -- Really? KootK (Structural) (OP) I am pretty sure the compressive strength of the standard plywood is less than that of a spruce or fir sill plate. Advantech may be a different story. The only time I have ever concerned about perp compression crushing (truss bearing aside) is during building shoring.

In mineral processing or metallurgy, the first stage of comminution is crushing.. Depending of the type of rock (geometallurgy) to be crushed, there are 2 largely different techniques at your disposition for crushing rocks. In principle, compression crushing is used on hard and abrasive rocks by placing them between a high wear-resistant plate/surface.

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. C 0 can be estimated from porosity or sonic velocities, but many
