WitrynaImportance of impact test. The primary purpose of performing this experiment is to find whether the material is brittle or ductile. Materials that break without plastic deformation (no energy absorption) is known as a brittle material. Material breaks with large plastic deformation (little energy absorption) are known as ductile material. WitrynaIn mechanics, an impact is a high force or shock applied over a short time period when two or more bodies collide.Such a force or acceleration usually has a greater effect than a lower force applied over a proportionally longer period. The effect depends critically on the relative velocity of the bodies to one another. At normal speeds, during a perfectly …
