Products of tomorrow are characterized by environmental sustainability, individuality and economic feasibility. This trend also occurs in the field sheet metal forming. Lightweight materials such as magnesium alloys applied to reduce weight concluding CO2 emissions cars. They a high specific strength almost inexhaustible availability. Applying them innovative forming technologies offers chance for various new products. Flexible single-point incremental (SPIF) have been newly developed meet...
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 Point Incremental Forming (SPIF) tested by applying full-area pneumatic pressure determine diaphragm’s...
Given the use of high-strength steels to achieve lightweight construction goals, conventional shear-cutting processes are reaching their limits. Therefore, so-called high-speed impact cutting (HSIC) is used required cut surface qualities. A new machine concept consisting linear motors and an mass presented investigate HSIC. It allows all relevant parameters be flexibly adjusted measured. The design test bench, as well mechanism for coupling mass, described. To validate theoretically...
The hole expansion test according to ISO 16630:2009 is a widely used method for determining the edge crack sensitivity, e. g. advanced high strength steels (AHSS). However, optical detection causes subjective stop of test, which also difficult automate. These existing disadvantages are eliminated by newly developed using pressure drop at an through entire sheet thickness. pneumatic ensures degree objectivity and automation. functionality new stopping was experimentally proven comparison with...
Kinder und Jugendliche mit einer Geschlechtsdysphorie, die an spezialisierten Ambulanzen vorstellig werden eine medizinische Behandlung ersuchen, stellen heterogene klinische Population dar. Manche der Betroffenen weisen neben Geschlechtsdysphorie zusätzlich komorbide psychiatrische Störungsbilder unterschiedlichen Schweregrads auf. Der vorliegende Artikel widmet sich in diesem Zusammenhang den komplexen behandlungstechnischen Herausforderungen, bei Jugendlichen Persönlichkeitspathologien...
Abstract According to the standard ISO 16630, hole expansion test (HET) has be stopped at instant when first through-thickness crack appears edge of hole. The detection is challenging, since maximum opening width should not exceed 0.1 mm inner diameter according newest version from 2017. A pneumatic been introduced in which a pressure drop used identify crack. In present paper, this method for stopping validated. It was tested steels with different sensitivities and compared force method....
Abstract Non-destructive monitoring of metal hardness is important for process and product quality assessment. In this paper, a partially hardened sample assessed in regards to physical effects using multi-frequency inductance spectroscopy. For purpose, the influence change conductivity, permeability stress on spectra are analyzed. To extract numerical values permeability, measured compared analytical model. Statistical analysis with principal component conducted fuse spectral data into...
Incremental sheet metal forming offers the possibility of producing formed parts in small batches efficiently and a resource-saving manner. However, order to exploit this potential, high level process understanding process-relevant material data are required. Based on experimental simulation-based examinations, limit curve (FLC) fracture line (FFL) determined predict failure critical geometry elements part (e.g., wall angle > 65°) by means FEM avoid it via adaptation. These experimentally...
