what is meant by compressive strength
Compressive Strength. Compressive strength is defined as the maximum compressive load a body can bear prior to failure, divided by its cross sectional area. Ceramics typically have good tensile strengths and are used under compression e.g. concrete.ield strength is defined as the stress at which a material changes from elastic deformation to plastic deformation. Once the this point, known as the yield point is exceeded, the materials will no longer return to its original dimensions after the removal of the stress.
In other words, tensile strength resists tension (being pulled apart), whereas compressive strength resists compression (being pushed together). Ultimate tensile strength is measured by the maximum stress that a material can withstand while being stretched or pulled before breaking. In the study of strength of materials, tensile strength, compressive strength, and shear strength can be analyzed independently.
