Crack Propagation under Water Pressure

However, the knowledge of water pressure within the cracks is relatively limited and is often neglected or just roughly estimated. This study aims at investigating how to design an experimental model to evaluate the crack propagation behaviour under the influence of water pressure and how tomography can be used to visualize the crack propagation.

The aim is to get a description of the possibilities and constraints of this combined technology areas as well as the workflow, and thus indirect working time, to use the method of calculating fracture opening along the crack path suitably.  Knowledge about the water pressure inside the cracks and interfaces is important for a safer design of hydraulic structures.
