Dynatup Falling Weight Impact Machine

The Dynatup 8250 Instrumented Falling Weight Impact Machine (IFWIM) is a component impact tester. (see also Instron-Dynatup). This machine is versatile, as far as the capacity is concerned (low to high impact energy), as well as the specimen geometry. Beam like specimens can be tested, as well as plates and more complex geometries. A data acquisition system based on an oscilloscope is used to monitor force and mass displacement.
