The Griffith theory of brittle fracture, also known as the Griffith criterion or Griffith's law, is a fundamental theory that explains how and why brittle materials such as glass and ceramics fracture under stress. The theory was first proposed by … [Continue reading]
What is Rockwell Hardness Test
The Rockwell hardness test is a popular method for measuring the hardness of a material, usually metals. It involves applying a constant load to the surface of the material using a diamond or tungsten carbide indenter, and then measuring the depth of … [Continue reading]
What is Brinell Hardness Test
The Brinell hardness test is a method for measuring the hardness of a material, typically metals, by indenting the surface of the material with a hard, spherical indenter. The test was developed in Sweden by Johan August Brinell in 1900 and is widely … [Continue reading]
What is Vickers Hardness Test
The Vickers hardness test is a commonly used method to measure the hardness of a material. It involves pressing a diamond indenter into the surface of the material at a specific load and for a specific amount of time. The size of the resulting … [Continue reading]
Phase Diagram | Types of Phase Diagram
A phase diagram is a graphical representation of the various phases or states of matter that a substance can exist in, as a function of temperature, pressure, and composition. It is a tool used in the field of thermodynamics to analyze and … [Continue reading]
