2Charpy impact test — noun 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 …
3Impact force — An impact force is a high force or shock applied over a short time period. Such a force or acceleration can sometimes have a greater effect than a lower force applied over a proportionally longer time period. Theory At normal speeds, during a… …
4impact test — Test of the ability of a material to withstand impact, used by engineers to predict its behaviour under actual conditions. Many materials fail suddenly under impact, at flaws, cracks, or notches. The most common impact tests use a swinging… …
5Charpy test — a test to measure the impact properties of steel. A prepared test piece, usually notched, is broken by a swinging pendulum. The energy consumed in breaking the test piece is measured in Joules. The more brittle the steel the lower the impact… …
6impact test — a test designed to give information on how a specimen of a known material will respond to a suddenly applied stress, e.g. shock. The test ascertains whether the material is tough or brittle. A notched test piece is normally employed and the two… …
7Izod impact strength test — Izod impact strength testing is an ASTM standard method of determining impact strength. A notched sample is generally used to determine impact strength.The test is named after the English engineer Edwin Gilbert Izod (1876 1946), who described it… …
8pendulum impact test — The standard test methods are the Izod and Charpy tests; the specimens have a standard notch machined in them, and the impact energy absorbed in breaking the specimen is recorded …
9Strength of materials — Internal force lines are denser near the hole, a common stress concentration In materials science, the strength of a material is its ability to withstand an applied stress without failure. The applied stress may be tensile, compressive, or shear …
