Available in PDF, EPUB and Kindle. Book excerpt: Abstract: High velocity forming methods successfully address problems faced in conventional forming techniques. They can be effectively used for forming metals with low formability like aluminum alloys and high strength steel. They can be instrumental is manufacturing of lighter vehicles with higher fuel efficiency. Electromagnetic forming (EMF) is an HVF method that is gaining wide acceptance due to its advantages and scope for commercialization. A number of experimental studies were carried out with EMF with the main goal of exploring fundamentals about material formability at high velocities, which can be used to establish practical design guidelines and to make models of high velocity formability. Thus the main factors that influence high velocity formability -- inertia / size effects; changes in constitutive behavior; impact; and dynamic failure modes, were studied mainly with experiments. The role of changes in constitutive behavior in improving formability was studied from existing studies and new theoretical studies involving High velocity Forming Limit Diagram (FLD) and through solving an inverse problem of ring expansion. Tube free-expansion experiments were carried out to demonstrate enhanced metal formability even in the absence of die impact. To further establish the significance of inertia, electromagnetic ring free-expansion experiments with rings of different aspect ratios were carried out. The results clearly demonstrated the influence of sample aspect ratio (dimensions) and hence inertia on high velocity formability. Die impact experiments were carried out with tubes and rings to show the beneficial influence of die arrest of a moving sample. It was revealed that die impact in an appropriate range of velocities can significantly suppress failure and reduce the number of tears and fractures in the samples. Further a new mode of failure in die impacted samples, spall-like dynamic rupture was observed, which had characteristics similar to classic spall failure. Thus through all these studies, the important factors influencing high velocity formability was studied and it was shown that it can be more complex than quasi-static formability. Boundary conditions for each forming operation can play a more significant role and hence simple tools like FLDs might not be practical tools for studying high velocity formability.

This book was released on 2013 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main objective of the HI-VEL project is to establish the feasibility of high velocity forming methods and to quantify the enhancement achievable with these techniques in the formability of high strength steel (HSS) and stainless steel sheets and tubes for automotive applications. Electromagnetic forming (EMF) and electrohydraulic forming (EHF) processes were studied during the HI-VEL project. After a first mechanical characterisation at strain rates up to 1000s-1, the following materials were selected for the high velocity experimental testing: AISI441 (1.4509), HT800XD (DP800), Dogal800DPX (DPX800), HT700TD (TRIP700) and IF210. The materials constitutive data at high strain rates were obtained for the Johnson Cook material modelling. EMF and EHF simulations were validated with experimental high velocity tests. The fatigue behaviour of high velocity formed samples was similar to the conventionally formed ones. Due to the low electrical conductivity of the HSS and stainless steels, the EMF technology showed its viability for these materials only in the case of small forming grades applications, such as the electromagnetic sizing of U-parts in order to eliminate the elastic recovery. For any other deep drawing operation, EMF technology can be applied to steels using an electrical conductive driver that accelerates the steel part towards the die. Comparing the conventional bulge forming and the multi-impulse EHF, the obtained dome heights increased from 57 to 70 mm for TRIP700 steel and from 48.5 to 54 mm for DPX800 steel. Multi-impulse EHF increased the formability of HSS and has interesting industrial applications, such as forming undercut part designs using a split die.

Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Electromagnetic forming via die impact has shown results beyond normal forming limits but there is little experimental research presenting the potential of kinetic type presses. This thesis introduces a suite of sheet metal forming methods to assess forming velocity's affect on plane-strain formability using ten different materials within three different categories of sample dimensions. In addition to strain rate effects from each technique, lubricant is varied on self-similar forming dies to investigate impact geometry and frictional conditions. Three very different 'press' types are used to apply a large uniform pressure over flat sheet materials into a single sided die that is accompanied by no draw-in of the material. These presses include a traditional quasi-static press, QS; an electromagnetically driven high speed press, HSP; an electromagnetically driven uniform pressure actuator, UPA; and an electromagnetically exploded foil, EF. Experimental energy requirements for electromagnetic forming, EMF, limits are reported along with characterization of the HSP peak current and velocity through the use of a Photon-Doppler Velocimeter, PDV. Cross-sectional photographs and thickness strain measurements are presented to see the strain rate effects on the samples. The resulting methodologies allow for predictions of shearing conditions and forming limits of nominally flat grooved structures.
