Minerva-Gentner Symposium: Burchard of Mount Sion’s Descriptio Terrae Sanctae
(2023-03-09)
The Minerva-Gentner Symposium on Burchard of Mount Sion’s Descriptio Terrae Sanctae, organized by Ingrid Baumgärtner and Jonathan Rubin, was held at Bar-Ilan University in Ramat Gan, Israel, from 28 November to 1 December 2022. In the workshop, German, Israeli, Italian and British scholars discussed the challenges – on the level of content, textual philology and technology – of publishing this work in print and digital form. The focus of the discussion was on questions relating to the new edition of the Descriptio , ...

Methoden zur Beurteilung der statischen Brauchbarkeit von Tragwerken
(Institut für Baustatik und Baudynamik, Universität Stuttgart, 2020)
Fehler in der Tragwerksplanung können zu kinematischen (beweglichen) Tragwerken führen, die aus statischer Sicht unbrauchbar sind. Mit dem Ziel, den Statiker beim Auffinden und Beheben derartiger Fehler zu unterstützen, müssen spezielle Methoden entwickelt werden. Dieser Beitrag enthält einen Überblick über klassische und moderne Methoden. Dabei erfolgt eine Klassifizierung in indirekte, direkte, Ursachen-spezifische und akademische Methoden.

Multicomponent Injection Molding Of Thermoplastics And Liquid Silicone Rubber (LSR) – Either Cured By Heat Or UV Light
(Society of Plastics Engineers, 2016)
For processing thermally curing liquid silicone rubber (LSR) as well as UV light curing LSR for multicompo-nent injection molding with thermoplastics in an compa-rable way a processing center was designed and set into operation.
For the production of the multicomponent specimens a modular tool was designed. In there a thermoplastic plate gets molded on the one side, then gets transferred auto-matically by a robot system and gets overmolded by the silicone on the other side. The complete silicone side of the tool is ...

Utilizing Continuous Kernels for Processing Irregularly and Inconsistently Sampled Data With Position-Dependent Features
(2023-03-13)
Continuous Kernels have been a recent development in convolutional neural networks. Such kernels are used to process data sampled at different resolutions as well as irregularly and inconsistently sampled data. Convolutional neural networks have the property of translational invariance (e.g., features are detected regardless of their position in the measurement domain), which is unsuitable for certain types of data, where the position of detected features is relevant. However, the capabilities of continuous kernels ...

On the Challenges toward Realization of Functionally Graded Structures by Electron Beam Melting—Fe-Base Shape Memory Alloy and Stainless Steel
(ASTM International, 2020-09-22)
In the present study, an iron-manganese-aluminum-nickel (Fe-Mn-Al-Ni) shape memory alloy was processed on an austenitic steel (AISI 304) build platform by electron beam melting in order to study the feasibility of realizing functionally graded structures consisting of two different materials (i.e., a functional and a structural material). Compression specimens consisting of the processed shape memory alloy and the austenitic build platform in equal parts were investigated. The microstructure was analyzed in the ...

Blending CA with PBS to increase the bonding strength in two-component injection molding
(Society of Plastics Engineers, 2019)
Since CA shows no adhesive properties in the two-component injection molding process with bio based TPU, blends of CA and PBS were produced to decrease the interfacial tension between the materials. While the interfacial tension was calculated from the results of a drop shape analysis, the adhesion strength was measured in peel tests according to the guideline VDI 2019. The comparison of the results gave information about whether the drop shape analysis is a valid method to analyze the adhesive characteristics of ...

Natural fiber reinforced technical (bio-) composites modified with halogen-free flame retardants
(Society of Plastics Engineers, 2019)
Under the aspect of sustainability and the use of alternative materials, engineering thermoplastics such as polybutylene terephthalate (PBT) will be reinforced with renewable raw materials such as regenerated cellulose fibers.
The University of Kassel is developing cellulose regenerated fiber reinforced technical thermoplastics in a state-funded project with further companies. Since pure natural fibers cannot withstand the high operating temperature of engineering thermoplastics (Ts>230°C), regenerated cellulose ...
