Abstract
Strain localisation in soils and rocks has been studied extensively for the last 40 years or so. On the experimental side, a large number of these studies have been devoted to the experimental observation of localised deformation in laboratory element tests like biaxial (plane strain) and triaxial tests. 2D and 3D imaging techniques and image analysis methods have been used to characterize the onset and subsequent development of strain localisation. In the recent years, these techniques and methods have improved dramatically, allowing considerably more accurate measurement of displacement and strain field in the laboratory specimens. It is time to have a second look, with these new glasses, at some decades-old results, to assess what can be confirmed and what should be reconsidered.
