Zusammenfassung Die mangelnde Verfügbarkeit von präzise charakterisierten Kugeln im Submillimeterbereich schränkt derzeit die Leistungsfähigkeit Mikro- und Nano-Koordinatenmessgeräten ein. Aus diesem Grund werden am Institut für Prozessmess- Sensortechnik der TU Ilmenau neue Ansätze zur Messung solcher untersucht daraus entsprechende Messverfahren entwickelt. Ein vielversprechender Ansatz basie...

The design of multi stage deep drawing processes requires the evaluation of many process parameters such as the intermediate die geometry, the blank shape, the sheet thickness, the blank holder force, friction, lubrication etc..These process parameters have to be determined for the optimum forming conditions before the process design. In general sheet metal forming may involve stretching drawin...

In this paper, local-thickened plates are adopted for aluminum alloy square cups stamping with relatively low values of residual stresses and small radius at the bottom corner. By utilizing numerical experimental methods, effects process parameters plate local thickening on stress distribution hot stamped studied. Furthermore, influence corner is also investigated. The results showed that an in...

Springback in sheet bending is a well-defined phenomenon; however, variation of springback difficult to control causing quality problems especially mass-produced goods such as home appliances. As an alternative straight flanging, the rotary die process offers reduced well geometric variation; there little knowledge literature. The effects parameters on behavior flanging and applied appliance si...

This article studies network resilience against structured additive perturbations to its topology. We consider dynamic networks modeled as linear time-invariant systems subject of bounded energy satisfying specific sparsity and entry-wise constraints. Given an level, the pseudospectral abscissa captures worst-possible perturbation adversary could employ destabilize network, stability radius is ...

Rotated clinching is a novel cold plastic deformation joining process, which suitable for the multi-point simultaneous of sheet metals. However, effect various parameters on mechanical properties joints using rotated remains unclear. The purpose this study to analyse important that affect joint’s shearing strength and relationship between them. relational expression four process (die depth, rot...

Background:   Iran places sixth amongst high risk natural disaster countries and Guilan province of Iran shoulders a large amount of socio-economic burden due to snow catastrophes. The more knowledge of circumstances we have, the more efficient our future encounters will be. Methods: In this retrospective study, of all of the patients admitted to Poursina Hospital due to snow and ice related tr...
