Compressive Strength
Compressive strength is the capacity of a material to withstand loads tending to reduce size. Explained differently, compressive strength resists compression (being pushed together), whereas tensile strength resists tension (being pulled apart).

Fracture Toughness
The ability to resist fracture is a mechanical property of materials known as fracture toughness. For advanced ceramics it uses a critical stress intensity factor known as KIC where the fracture normally occurs at the crack terminations.

Flexural Strength
Flexural strength, also known as bending strength, modulus of rupture or transverse rupture strength, is defined as the maximum stress in a material just before it yields in a bending test
