Materials testing is the process of evaluating the physical properties and behavior of materials like metals and plastics under various conditions. This testing ensures the safety and reliability of products, structures, and materials. Load cells, which measure the force applied to a material during testing, play a crucial role in determining material characteristics such as strength, flexibility, elasticity, ductility, and durability.
Materials testing machines incorporate load cells to measure the controlled force applied to the material being tested. The force parameters depend on the material and the property being measured, including tension, compression, shear, and torsion.
Tensile and peel testing use tension load cells like tension links or S-types to measure the tensile force applied. These tests determine properties like tensile strength, modulus, elongation, and Poisson's ratio, as well as adhesive peel strength.
Compression load cells like beam, canister, button, or donut cells measure the force applied during compression and impact testing. These tests evaluate properties like elastic limit, yield point, compressive strength, and energy absorption.
Shear web and torsion load cells measure stress from angular displacement in torsion tests, determining properties like shear modulus, shear strength, and ductility.
These tests can involve tension, compression, universal, torsion, or shear load cells, depending on the testing machine. They measure properties like flexural strength, modulus, rupture, and fatigue life under cyclic loading.
Adhering to industry regulations and standards requires accurate measurement from load cells. Electronic strain gauge load cells are preferred for their dynamic range, reliability, and cost-effectiveness, but must be regularly calibrated and properly mounted.
