Pendulum Impact Testing Machines

The various methods allows for the determination of the necessary energy to break a specimen – having a known cross-section - then calculating its resilience value at a given conditions. The potential energy of the hammer is known and it varies depending on the hammer’s shape, weight and release angle. The absorbed energy to break the specimen can be determined after measuring the ascent angle of the hammer after the impact. The test methods to perform with this structure are Charpy, Izod and Tensile Impact. Differences among these test methods are related to the way the specimen is mounted and how it is impacted.

Test Methods:

1. Charpy.
2. Izod.
3. Tensile Impact
