Qualitative and quantitative properties of the dynamics of screw dislocations

, 2017
This note collects some results on the behaviour of screw dislocation in an elastic medium. By using a semi-discrete model, we are able to investigate two specific aspects of the dynamics, namely (i) the interaction with free boundaries and collision ...

Simplified theory of the Archimedian screws

, 2009
The Archimedean screw pump is one of the oldest hydraulic machines. Today, it is employed in pumping as well as - operating in reverse - in an energy conversion role. Despite its age, no consistent theory links the screw’s geometry with its mechanical efficiency. Based on geometrical parameters and an idealised energy conversion process for one turn of
