Impact Testing: The purpose of impact testing is to measure an object's ability to resist high-rate loading. It is usually thought of in terms of two objects striking each other at high relative speeds. A part or material's ability to resist impact often is one of the determining factors in the service life of a part, or in the suitability of a designated material for a particular application. Impact resistance can be one of the most difficult properties to quantify. The ability to quantify this property is a great advantage in product liability and safety.
Tensile or Compression Testing is Not Enough!
In standard testing, such as tensile and flexural testing, the material absorbs energy slowly. In everyday life, materials often must absorb energies very rapidly from falling objects, blows, collisions, drops, etc. Instrumented Impact testing is designed to simulate these conditions.
- Does your material or product get dropped, kicked, knocked.impacted in any manner?
- Do you only do tensile, compression, or flexural testing at set speeds?
- Do you know how your product behaves in cold temperatures vs. room temperature?
- Do pass/fail Izod, Charpy or Gardner tests leave you with unanswered technical questions?
- Do you know exactly when and how your product fails versus just the final failure point?
- Do you know how your product stands up to knocks, drops, kicks, and other damage caused by impact?
- Wouldn't you like to "see" how your product withstands real life conditions?
WMT&R offers a line of Instrumented Impact Testing designed to meet these needs.
- Penetration testing of thick panel specimens such as graphite-epoxy, fiberglass, polycarbonate and sheet steel.
- Energy absorption and fracture resistance testing of large components including pipe, appliance housings, safety helmets, and automotive components.
- Three-point bend testing to ASTM specification geometries such as ASTM E-604 dynamic tear test, ASTM E-436 drop weight tear test, and ASTM E-208 nil-ductility test.
