Abstract
An apparatus and method for measuring the puncture resistance of an aluminum can that has improved repeatability and more accurately simulates end-use punctures. A penetrator that moves in a horizontal direction and is driven by a falling weight impacts a pressurized aluminum can containing liquid. The aluminum can is impacted by a penetrator of the puncture gauge in an area below the liquid level. Various sensors, such as a load cell and a displacement transducer, measure data from the impact and the data is compiled and analyzed by a data acquisition system.
