using
a combined experimental/numerical approach. In addition, theoretical predictions from two approaches,
waterhammer theory and a mass-spring model, are also given. Experimental tests are conducted using
a specially designed rig for testing plastic containers (bottles). Tested containers are fully instrumented
with pressure transducers and strain gauges. The experiments are simulated using a two-system fluidstructure
interaction procedure based on the Finite Volume Method. Good agreement is found between
measured and predicted pressure and strain histories. Results obtained are in favour of waterhammer
theory.
