Impact Engineering Laboratory and facilities

Impact Engineering Laboratory at Swinburne University of Technology is Australia's leading research group for studying the behaviour of innovative materials and structures under dynamic/impact loadings.

We specialise in dynamic material testing, material characterisation, structural and product drop tests, ballistic projectile penetration tests as well as computational simulations of various dynamic processes.

We also provide material and structural testing services to not only researchers at Swinburne, but also researchers in other universities, research organisations and industries.

Research is focused on investigating energy absorption of light-weight materials and structures, exploring new paradigms for material and structural behaviour, and exploiting optimal design for novel structures under various loadings.
