Due to the danger associated with handling explosives, inert simulant materials called mocks are often substituted in non-detonative tests. The pharmaceutical idoxuridine has recently been of interest in the search for a high fidelity thermomechanical mock for HMX due to similar thermal and quasistatic mechanical properties. In order to investigate the range of conditions under which the two materials are comparable, single crystals of each material were subjected to mechanical loading quasistatically via nanoindentation, and plastic bonded composites of each material were loaded dynamically via split Hopkinson pressure bar testing. Additionally, dynamic testing was performed over a range of temperatures for both materials. Mock suitability is therefore assessed here as both a function of strain rate as well as temperature, and comparisons are made between both single crystal and polymer matrix composite systems.
