This study investigates the deformation and fracture mechanisms of two testing methods, tension under cyclic bending (TCB) plus compression (TCBC) their relationship to single point (SPIF) double-sided (DSIF) incremental sheet forming processes. Experimental tests were carried out by using a bespoke TCBC test rig DSIF machine with grade 1 pure Ti samples. The results show elongation-to-fracture...

Research in the last 15 years has led to die-less incremental forming processes that are close to realization in an industrial setup. Whereas many studies have been carried out with the intention of investigating technical abilities and economic consequences, the ecological impact of incremental sheet forming (ISF) has not been studied so far. Using the concept of exergy analysis, two ISF techn...

Abstract This article outlines the development of an elastically foldable, bistable diaphragm geometry that enables increase in compression volume compressors compared to use flat diaphragms. Using a Finite Element Model (FEM) ABAQUS/Standard, several membrane geometries (truncated cone, and dome) were calculated analyzed with regard their elastic deformation. Selected produced using Single Poi...

In this study, the incremental forming of explosively welded low carbon steel-commercially pure titanium bilayer sheet has been experimentally and numerically investigated. For this purpose, at first a finite element based analysis was proposed to predict forming force and thickness distribution to form this material by such process, that showed good agreements with the experimental results. Th...

background : this study was set to determine the optimal technique of breast cancer with supraclavicular fossa irradiation. methods : three techniques was compared in this study. techniques were two point symmetric (2p-sym), two point asymmetric (2p-asym) and single point (sp). in 2p-sym all of beams were symmetric, in 2p-asym tangential beams were symmetric and supra was asymmetric, in sp all ...

The aim of this paper is to analyze the effect process parameters on coefficient friction (COF) in single-point incremental forming process. This investigation may be useful for further FEM analyses where tool-workpiece contact must set appropriately obtain adequate results. was analyzed between a solid tungsten carbide ⌀8 hemispherical ended tool with radius 4 mm and grade 2 pure titanium shee...
