摘要:Abstract(#br)A comprehensive combined hybrid numerical-experimental program is executed on three advanced high strength steels (DP980, CP980 and CP1180) with the objective of validating (1) the hypothesis of a positive strain rate effect on the ductility under biaxial tensio...

摘要:Abstract(#br)Mars ® 300 is an ultrahigh hard armor (UHHA) martensitic steel designed for ballistic protection. It is available in sheets of different thicknesses and also as perforated plates with a periodic pattern of cylindrical holes. Installed as an add-on layer in front...

摘要:Abstract(#br)Basic ductile fracture experiments for sheet metal (or flat coupons extracted from bulk material) are presented to characterize the onset of fracture at different stress states. Special emphasis is placed on designing the experiments such that the stress triaxiality ...

摘要:Abstract(#br)Low, intermediate and high strain rate tensile experiments are carried out on flat smooth, notched and central-hole tensile specimens extracted from advanced high strength steel sheets. A split Hopkinson pressure bar testing system is used in conjunction with a ...

摘要:Abstract(#br)When a long slender structure such as a wire, strut or rope is loaded under tension all the way to fracture, upon failure an elastic unloading wave propagates down the wire and reflects as a compressive wave from the distant clamp end. The compressive effect of ...

摘要:Abstract(#br)The large deformation response of Ti–6Al–4V parts made through additive layer manufacturing is investigated. A wire-feed process is chosen instead of a powder process in an attempt to reduce the oxide contaminations of the final part. The experimental program in...
