The dynamic fracture of a body is a late-stage phenomenon typically studied under simplified conditions, in which a sample is deformed under
uniform stress and strain rate. This can be produced by evenly loading the inner surface of a cylinder. Due to the axial symmetry, as the cylinder
expands the wall is placed into a tensile hoop stress that is uniform around the circumference. While there are various techniques to generate
this expansion such as explosives, electromagnetic drive, and existing gas gun techniques they are all limited in the fact that the sample cylinder
must be at room temperature. We present a new method using a gas gun that facilitates experiments on cylinders from 150 K to 800 K with a
consistent, repeatable loading. These highly diagnosed experiments are used to examine the effect of temperature on the fracture mechanisms
responsible for failure, and their resulting influence on fragmentation statistics. The experimental geometry employs a steel ogive located inside
the target cylinder, with the tip located about halfway in. A single stage light gas gun is then used to launch a polycarbonate projectile into the
cylinder at 1,000 m/sec-1. The projectile impacts and flows around the rigid ogive, driving the sample cylinder from the inside. The use of a nondeforming
ogive insert allows us to install temperature control hardware inside the rear of the cylinder. Liquid nitrogen (LN2) is used for cooling
and a resistive high current load for heating. Multiple channels of upshifted photon Doppler velocimetry (PDV) track the expansion velocity
along the cylinder enabling direct comparison to computer simulations, while High speed imaging is used to measure the strain to failure. The
recovered cylinder fragments are also subject to optical and electron microscopy to ascertain the failure mechanism.
