Materials Testing

Materials Testing
Material testing is vital in the verification process, determining the right material and reliability for an application as well as meeting regulatory and standardized requirements. The materials that go into all products, equipment and technologies we rely upon everyday must be thoroughly tested for safety, performance, and other criteria, before the first product can come off the assembly line. "

The testing of materials help engineers and designers to choose the best material for a particular use. Knowing a material's various characteristics; its strengths and weaknesses, its load, stress, and strain parameters under varying environmental conditions, is essential to safe, efficient and cost effective design.

FAQ's

Materials testing, measurement of the characteristics and behavior of such substances as metals, ceramics, or plastics under various conditions. The data thus obtained can be used in specifying the suitability of materials for various applications—e.g., building or aircraft construction, machinery, or packaging.

The Importance of Materials Testing. ... For manufacturers, it is of the utmost importance to understand the mechanical properties of materials that exhibit some Hookean behavior during loading. It is important because the performance of a structure is frequently determined by the amount of deformation permitted.

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.

Once the properties of a given material are characterized and understood, this information can provide the higher level of understanding that is needed to resolve important issues such as cause of failure and process-related problems, as well as to make critical materials decisions.

Mechanical Testing Services. ... Designed to ensure that materials are suitable for their intended applications, mechanical testing includes methods such as tensile strength and elongation, compression strength, impact resistance, fracture toughness, stress rupture, fatigue limits, hardness, and more.
