What is Impact Strength?

What is Impact Strength?

Impact strength – also called impact toughness – is the amount of energy that a material can withstand when the said load is suddenly applied to it. It may also be defined as the threshold of force per unit area before the material undergoes fracture [1].. The s trength of materials may be defined in many ways, and some of the most common parameters include tensile strength, yield strength ...

Impact Force

Impact Force

In an impact like a car crash the work made by the impact force slowing down an moving object over a distance by deforming the crumple zone can be expressed as. W = F avg s (2) where . W = work done (J, ft lb) F avg = average impact force during deformation (N, lb f) s = deformation distance, crumple zone (m, ft) When a crumple zone deforms in a car crash the average impact force is ...

Size reduction in impact crushers occurs through particle concussion by rigid forces. The hammer crusher, also called the hammer mill, is an example of an impact crusher. In hammer crushers, hammers swing freely on a disc mounted on the main shaft within the device . As the disc rotates, the feed material is struck and crushed by descending hammers until it is fine enough to pass through a ...

The force is measured by the force sensor during impact; for the purpose of the present study, the measured results of force will be analyzed in future studies. After the impact event, some impact energy could be retained as the kinetic energy of the drop weight if it rebounds or pitches down, which can be recorded with the highspeed camera (up to 7960 images/s with a resolution of 1920 × 1080).
