The shear stress - shear rate - time relationship of wet and soft soils is determined from the point of view of dislocation theory. Theoretical analyses and experimental results show that shear stress of soils is a power function of shear rate. The relative shear stress comparing with shear str...

This "superplastic crack" will therefore have an associated region of concentrated shear stress around its perimeter which, at typical rock temperatures of greater than half the melting point, will continuously promote dynamic recrystallisation. In this way the fault is self-propagating until growth ...
