Dynamic stiffness testing

Our indenter rigs measures the dynamic stiffness of compliant materials and components, and the dynamic characteristics of parts such as dampers, springs, mounts and isolators.

Applications include:

seating and cushioning
vehicle and machinery mounts
packaging and protective materials

They can also be used for quasi-static compression testing, to measure load-deflection curves.
