Mechanical Testing

Mechanical testing reveals the elastic and inelastic behavior of a material when force is applied. A mechanical test shows whether a material or part is suitable for its intended mechanical applications by measuring elasticity, tensile strength, elongation, hardness, fracture toughness, impact resistance, stress rupture, and fatigue limit.

How Element experts conduct mechanical testing

The instruments and machinery you'll find in a Element mechanical testing department may include universal test machines, microhardness testing and hardness testing machines, bend and fatigue machines, as well computers featuring programmable software. Our highly trained scientists, engineers and technicians use these devices to run mechanical testing programs for clients in aerospace, automotive, biomedical, commercial, oil and pipeline, primary metals, construction, and other industries.

Customizing your mechanical testing program

A mechanical testing program from Element can include:

  • Hardness and Microhardness Testing is the measure of how resistant solid matter is to various kinds of permanent shape change when a force is applied. Methods include: Rockwell standard testing, Rockwell superficial testing,  Knoop & Vickers microhardness testing, and  Brinell hardness testing.
  • Tensile Testing subjects a sample to uniaxial tension until it fails. Element tensile testing capabilities include: wedge tensile testing, axial tensile testing, weld tensile testing, castings tensile testing, elevated temperature tensile, tensile testing for machined specimens, full-size tensile testing and yield tensiles, plus heat treatment capabilities.
  • Torque Testing  is the tendency of a force to rotate an object about an axis. Element can perform torque testing on most hardware and fastener products.
  • Fatigue Testing  is performed on parts and materials to simulate the progressive and localized structural damage that occurs when a material is subjected to cyclic loading. Element's fatigue testing methods include:  fracture toughness testing, a measure of the fracture resistance of a material containing a crack; rotating beam fatigue testing; strain controlled axial fatigue testing; stress controlled axial fatigue testing, and da/dN testing (crack propagation rate).
  • Charpy Impact Testing: The Charpy impact test, also known as the Charpy v-notch test, is a standardized high strain-rate test which determines the amount of energy absorbed by a material during fracture. Element conducts sub-size Charpy impact testing and standard Charpy impact testing.
  • Bend Testing determines the ductility or the strength of a material by bending the material over a given radius. Element performs bolt bend testing, weld bend testing, and raw materials bend testing. 
  • Proof Load Testing is often used interchangeably with yield strength; it refers to the tension-applied load that a test sample must support without evidence of deformation. Proof load testing can be done on nuts, bolts, components, and assembled products. Methods include: tension testing, compression testing.
  • Shear Testing: Shear strength measures a material's response to shear loading, a force that tends to produce a sliding failure on a material along a plane that is parallel to the direction of the force. Element performs shear testing on bolts, rivets, pins, and other products: single shear testing, double shear testing, washer testing and other testing.
  • Other mechanical testing capabilities include mechanical durability, experimental stress analysis, flow measurement, fatigue analysis, structural testing, and pressure cycling.
