How Strong is PVC Pipe? (With PVC Strength Charts)
The above is a question very commonly asked. While it may seem like a simple question, how to define the strength of PVC pipe is far from straightforward. The term "strength" can mean a number of things, all of which cannot be covered in one blog post. The three types of strength measurements I will go into in this post are collapse pressure, burst pressure, and tensile strength. …

Calculate force to crush pipe. | Physics Forums
Diameter = 0.5". Wall Thickness = .0625". Material = Steel. i think you are looking for the "yield strength" after which point deformation to the pipe is permanent. You need an accurate description of the type of steel and it's modulus of elasticity. I'd assume the force per pipe is 3,000lbs/4 plates/30 pipes per plate = ~29 lbs.

Frac Sand Testing - Basics of Frac Sand Testing
Frac sand needs to be very strong. Strength is found using the crush resistance test. The crush resistance test is used to determine a "K Value," which is the pressure at which 10% or more of the sand starts to break into fines. High quality frac sand often has K values of 5K, 8K, 9K. Resin coated frac sand and ceramic proppants have even ...
