What is a Compressive Stress?

 · Compressive stress compresses a material by either crushing it or deforming it and ultimately causing it to fail during operation. There are two types of materials that exist: ductile and brittle. Once solidified, concrete is a brittle material, and when such materials are subjected to compressive stress, they just fracture because the stored energy in the material is suddenly released.
