Abstract

Using a gas gun to create rapid expansion in metal cylinders to investigate fracture and fragmentaion has been commonplace for the last several decades. Results from such experiments alongside data from explosive and electromagnetic expansion techniques have produced several models for fragment size and mass distributions. We present a new geometry for expansion that can be applied to cylinders at elevated & reduced temperatures whilst keeping the drive mechanism constant, enabling us in the future to experiment over a range of sample temperatures at a fixed strain rate and loading path. This new geometry has been investigated through a series of gas gun experiments employing X-ray radiography and AUTODYN simulations to reveal the deformation and failure behaviour within the cylinder.
