Geology paper on boundary conditions in simple shear analogue models

The August issue of Geology features a collaborative work of Marcel Frehner and Ulrike Exner, together with Neil Mancktelow from the ETH Zürich and Djordje Grujic at Halifax, Canada.

Unintended boundary effects like foldis or shear strain gradients at the boundaries of simple shear analogue rigs hinder a useful interpretation of quantitative data from analouge experiments. Combining 2D and 3D finite element models, we identify the non-trivial cause of these boundary effects and provide helpful instructions how to avoid or minimize them.
