formability of automotive friction stir welded twb (tailor welded blank) sheets isnumerically investigated in biaxial stretching based on hemispherical dome stretch (hds) test infour automotive sheets of aluminum alloy 6111-t4, 5083-h18, 5083-o and dp590 steel, havingdifferent thicknesses. the effects of the weld zone modeling and the thickness ratio on formabilityare evaluated. in order to car...

In the present study, a specific hydraulic press brake based test setup (HPBTS) was designed and manufactured which used to determine bending forces punch displacements of Hardox 400 steel depending on plate thickness, length mechanical properties. The equipped with an image processing system detect change angle during forming. Prior tests, tensile tests were carried out identified properties c...

Magnesium alloys have, in recent years, been recognized as highly promising biodegradable materials, especially for vascular stent applications. Forming of magnesium alloys into high-precision thin-wall tubes has however presented a technological barrier in the fabrication of vascular stents, because of the poor workability of magnesium at room temperature. In the present study, the forming pro...

Eukaryotic cells adhere to extracellular matrix during the normal development of organism, forming static adhesion as well cell motility. We study this process by considering a simplified coarse-grained model vesicle that has uniform energy with flat substrate, mobile-curved membrane proteins and active forces. find high concentration curved alone increases spreading vesicle, self-organization ...

Abstract. Incremental sheet forming is a relatively new technology with deformation strategy that resembles the layered manufacturing principle of rapid prototyping; thanks to this, it can represent viable way form metal and polymer sheets, guaranteeing high customization cost-effectiveness. On other hand, particularly when considering thermoplastic components obtained by this process suffer fr...

Similar to random sea waves, forces on the offshore structures due to waves are random. These forces can be mainly divided into two components, namely, inline forces and transverse or lift forces. The random nature of lift forces is more complicated than that of inline forces and both should be combined for design purposes. In the present paper, two different approaches have been used to determ...

Abstract Currently, a great deal of controversy exists regarding the real forces generated in drawbeads during sheet metal forming processes. The present work focuses on analysis uplift force. First, detailed literature review is carried out to analyse previous experimental procedures used measure forces. It found that setups do not perfectly replicate geometry industrial drawbeads. In order ob...

We demonstrate that the time evolution of van Hove dynamical pair correlation function is governed by adiabatic forces arise from free energy and superadiabatic are induced flow function. The consist drag, viscous, structural contributions, as occur in active Brownian particles, liquids under shear lane forming mixtures. For hard sphere liquids, we present a power functional theory predicts the...
