This thesis investigates the potential applications of the Sharpe Hollow Cavity Model (SHCM), the Gaussian Ball Source Model (GBSM), and the Heelan Cylindrical Model (HCM) in mod- elling explosive pressure sources.Each of these models account for the non-linear nature of wave propagation near an explosive source by mathematically altering the conditions around the source, and replacing it with a model that is more easily understood.
Both the SHCM and the HCM replace the source with a hollow cavity, within which waves do not behave linearly, and elastic waves are assumed to emanate directly from the surface of the cavity. The GBSM does not use a cavity and replaces the explosion with a Gaussian ball; elastic waves are then assumed to emanate from a point in space.
Each of these models were able to make reasonably accurate predictions about the nature of dynamite data measured in the feld.
