Materials are tested for diverse purposes: to determine the properties of the raw material, to check quality at intermediate stages in production processes, to check finished products, and to aid research. Mechanical, physical, and chemical methods are used to study the properties of materials.

• Destructive Testing/Mechanical Tests – • The material may be physically tested to destruction or indentation. • To measure the strength, hardness, toughness, etc. • Example: Tensile testing, Impact testing, Hardness Testing etc. • Non-Destructive Tests (NDT) • Samples or finished articles are tested before being used and as routine maintenance checks.

Test material meaning

Few materials possess a Yield Point, the most common examples are low carbon steel. If Yield Point (pt A) exists for a given material it will be indicated as the point on a stress strain curve where a zero or negative slope occurs prior to the Ultimate Tensile Strength. • Destructive Testing/Mechanical Tests – • The material may be physically tested to destruction or indentation. • To measure the strength, hardness, toughness, etc. • Example: Tensile testing, Impact testing, Hardness Testing etc. • Non-Destructive Tests (NDT) • Samples or finished articles are tested before being used and as routine maintenance checks. The test involves pressing the pyramid-shaped penetrator (with a gap angle of 136 degrees) into the material, with a given load that can vary from to 1-10 N (0.1-1 Kg). Knoop – An alternative microhardness measurement to Vickers, the only difference is the shape of the penetrator (indenter), which is an elongated diamond shape.
