Abstract. This second part of the paper is focused on double-action radial extrusion testing and modelling to characterize material formability failure in bulk-to-sheet flow transitions that are commonly found metal forming. Results show three-dimensional plane-stress evolutions at radially extruded flanges lead different modes fracture (by tension by shear) may or not be preceded necking. The ...

Strength and ductility are two of the most important mechanical properties of structural materials. However, they are often mutually exclusive, i.e., a material may be strong or ductile, but rarely both at the same time. This is also true for bulk nanostructured materials, which usually have high strength, but disappointingly low ductility. Bulk nanostructured materials are usually synthesized ...

Abstract In sheet metal stamping, the occurrence of strain localization in a deformed is considered failure. As so, metal’s formability conventionally evaluated using Forming Limit Diagram (FLD), which separates principal space into safety and unsafety regions by Curve (FLC). This study presents an evaluation method for detecting based on Digital Image Correlation (DIC) during experiment. The c...

Resolving the timing of initiation and propagation continental accretion associated with increasing topography exhumation is a genuinely challenging task using low-temperature thermochronology. We present an integrated thermo-mechanical thermochronology modelling study tectonically-inverted hyperextended rift systems. Model data sets for apatite (U-Th)/He, fission-track, zircon (U-Th)/He fissio...
