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.
Testing Includes:
• 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.
