Strain distribution within arcuate diapiric ridges of silicone putty

摘要: Abstract Twenty crescent-shaped diapiric models of silicone putty were made in two high-capacity centrifuges. The strain distribution within the was studied by means coloured rectangular elements, a method which led to large errors at random locations. Most elements affected could be identified repeated experiments. deformation pattern central segment ridges is dominated regions contrasting principal normal radial symmetry plane (axial crescents). This tensile near concave boundary ridge and compressive convex ridge. Within plane, orientation long axes total-strain ellipses resembles an open fan diverges toward crest In high-amplitude models, there narrow crestal region are subhorizontal. A similar has been noted comparable cylindrical ridges. one our (WMS 20), arcuate hinge line pronounced culminations both ends results strong depression where analysis performed. Accordingly, characteristic occupies most section.
