Compressive Strength

For metals, the compressive strength is the same as the tensile yield strength. Polymers are approximately 20% stronger in compression than in tension. In Ceramics, compressive strength is governed by crushing and is much larger than the tensile strength. Composites which contain fibres (including natural composites like wood) are a little weaker (up to 30%) in compression than tension because the fibres buckle.
