These applications often feature high strains, high strain rates, wide temperature ranges, contact with water and organic solvent mixes all of which can take place at large pressures. Attempting to understand and model just one of these effects would be difficult enough but to understand their full complexity when they are all acting in parallel is even more challenging. However, this thesis aims to lay the foundational work to build an all-encompassing model to help understand the behaviour of the elastomer materials that are found in mud motor stators. The work presented here focusses on material characterisation, static fracture and cyclic fatigue analysis over a range of temperatures together before and after ageing at high temperatures and in organic solvents. The materials used are typical compound formulations used in the oil and gas industry that u...
