We employ state of the art sample preparation and testing methods and equipment. Part size does not matter. Hardness of the part does not matter either.

The standard test for measuring impact energy is the Charpy test. This gives an indication of the characteristics of the material during fracture. An arm is swung down in a pendulum motion to impact with the test material.

The energy required to fracture the sample is recorded.

In the Charpy test, the test piece is held horizontally between two vertical bars, much like the lintel over a door. In the Izod test, the specimen stands erect, like a fence post. Joules to Joules, and we can . The test requires specimens made with a milled notch, hence the test is often referred to as the “notched bar impact test ”. FACTORS INFLUENCING ACCURACY OF CHARPY IMPACT TEST DATA REFERENCE: Lowe, A. Holt, Editor, American Society for Testing and Materials, Philadelphia, . The test is implemented by striking a small, rectangular metal specimen with a large pendulum and recording the energy absorbed by the specimen as it breaks. Accurately determining the . A test of the impact strength of a material, used to determine its relative ductility or brittleness.

The test is executed by swinging a large, heavy hammer on a pendulum from a predetermined height. The hammer fractures the material sample, usually a block of a certain size with . After careful tailoring, composite structures can provide a reasonable well response to impact loads with the additional advantages of weight savings and structural stiffness. In order to efficiently design composite structures for impact loads, reliable numerical models are required and sufficiently accurate material codes are . CONCLUSIONS The test method for dynamic fracture toughness of brittle polymers was studied from various viewpoints.

The of this study can be summarized as follows. The vibrational wave generated at impact in the load-deflection curve can be suppressed .

It strikes and breaks the specimen. Charpy method: The specimen is held horizontally, . It indicates how the material will respond. Zwick offers a broad spectrum of products and test equipment to satisfy all the requirements made of charpy impact testing.
