What is mechanical testing?
Mechanical testing reveals elastic and inelastic behavior of a material when force is applied. A mechanical test shows whether a materials or part is suitable for its intended mechanical applications by measuring elasticity, tensile strength, elongation, hardness, and fatigue limit.
What mechanical testing measures
An axle fights the pull of a low tire, a nail penetrates a hardwood block, an aircraft rivet battles against windspeed at 30,000 feet. Stork's mechanical testing programs provide the data companies need to build products that perform as expected—day after day, encounter after encounter.
How Stork experts conduct mechanical testing
The instrumentation you'll find in a Stork mechanical testing department may include universal test machines, microhardness/hardness 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.
A mechanical testing program can include:
- Hardness Testing including Rockwell standard and superficial, Knoop & Vickers microhardness testing, and Brinell testing;
- Tensile Testing including wedge, axial, weld, castings, elevated temperature, machined specimens, full-size tensile and yield – plus heat treat capabilities;
- Torque Testing for lock nuts, collars, eddy nuts, bolts-recess, and wrenchable nuts;
- Fatigue Testing including fracture toughness, rotating beam, and strain or stress controlled axial fatigue testing;
- Charpy Testing including subsize and standard, weld and HAZ, elevated and cryogenic temperatures;
- Bend Testing for bolts, welds, and raw materials;
- Fracture Toughness is a measure of the fracture resistance of a material containing a crack.
- Proof Load Testing tension and compression testing of nuts, bolts, components and full products;
- Shear Testing (single or double) for bolts, rivets, and pins.
- Washer Testing (inch or metric) hardness by Rockwell or microhardness for case and core hardness, twist test, compression test, interlocking test, temper test, clamping test, deflection test, surface roughness, and direct tension indicator washer tests.
