Types

The impact testing machine comprises a variety of types. These types test materials' ability to withstand sudden forces or impacts, such as collected data on how brittle or ductile they are.

• Charpy Impact Test Machine

  The charpy machine's swing frame releases a notched pendulum to strike a test specimen set in a crossing beam at room temperature. It measures toughness by how much energy the material absorbs before fracturing. Charpy tests help compare materials, select alloys to reduce brittleness, and examine heat-affected weld zones.

• Izod Impact Testing Machine

  The Izod machine swings a notched pendulum to hit a vertical test piece mounted on the machine frame. It gauges impact strength by seeing how much pendulum swing energy the specimen absorbs before breaking. Izod applied the test, helping choose plastics and metals for dynamic loads. Materials exhibit ductility or toughness under impacts.

• Drop Weight Impact Testing Machine

  Drop-weight testers use a freely dropped, heavy pendulum or "drop weight" onto a specimen to create controlled impact events. The test piece is often notched. Any resulting fractures are examined for energy absorption, damage progression, or yielding, depending on test parameters like dropped weight. Common applications include armor materials.

• Dynamic Mechanical Analyzer (DMA)

  Dynamical mechanical analysis establishes how viscoelastic materials behave under stress, strain, and time at varying temperatures and frequencies. DMA applies oscillatory force to a specimen and records its mechanical response as storage and loss moduli. It evaluates polymers for uses exposed to varying temperatures or loads, like car interior.

• Tensile Impact Test Machines

  This machine performs tensile impact tests by applying a high-velocity pendulum or jaw to stretch and fracture a specimen in seconds. It differs from slow tensile tests by providing data on behavior under rapid, unexpected loads. Results from dynamic versus quasi-static tests help designers account for strain rates in safety-culture applications.
