Key measurement in impact testing
Key measurement in impact testing
Energy absorbed to break specimen
Pendulum behaviour with tough material
Pendulum behaviour with tough material
Material absorbs lots of energy, pendulum doesn't swing far
Pendulum behaviour with brittle material
Pendulum behaviour with brittle material
Material breaks easily, pendulum retains most energy
