Materials’ Testing

Materials’ testing is the procedure that involves bending, pulling, twisting, hitting, squeezing and turning material to ensure that they can withstand intense strains, impacts and stresses they are expected to bare in their applications and uses. Materials’ testing scrutinizes the average toughness, flexibility, strength, fitness and suitability for application purposes.

However, this does not imply that the titanic rivets or the arena roof strength were not tasted, but helps to reduce the chances of using fault materials in a project. Materials’ testing is therefore very vital in the construction of man-made projects. It is not only steel, bricks, concretes and mortar which are tested, but everything is subject to material testing.

The Scope of Material Testing

Initially, materials were subjected to tensile and compression testing. These and were the earliest and the most familiar mode of material testing. However, as a result of increased customer demands, and the growth of testing industry, more complex material testing have been developed to determine how materials will react to real life applications. Materials’ testing departments has as well been developed especially Civil Engineering and Architectural Engineering organizations.

Often, material testing is the last thing in the process manufacturing, yet quality is the objective of the entire process. If the material which is used in certain project is defective, then the entire project may be defective too. It is fact that quality should not be the last process in manufacturing. Therefore, understanding the properties of materials will better assist to predict the outcome of manufacturing process.

Importance of Material Testing

Material profiles through stamps and operational forms play a significant in detecting various materials from suppliers. Actually, most material such as metals, plastics, textiles and polymers portray hookean characteristics. This implies that, material stress is directly proportional to the strain applied on the material. Therefore, it is very vital to comprehend the mechanical properties of the materials during loading. This is essential because the recital of structure is often determined by the deformation amount permitted. For instance, a slight deflection of optical grinding machine will lead to production of scrap lenses. When designing a structure, one should consider properties like yield strength, young’s modulus of elasticity and the tensile strength.

Another significant is the deformation ability, ductility in shear and tension especially in plastics. This is very significant in the process of manufacturing bodies of automobile or wire products. The most often used ductility indices include area reduction and total elongation. For suppliers, the mechanical properties of the material are vital measure of quality of the products while buyers need value certification.
