Rechnerische Analysen im Zuge der Dimensionierung und Substanzbewertung gewinnen im Betonstraßenbau zunehmend an Bedeutung. Eine hinreichende Kenntnis über das im nationalen Betonstraßenbau spezifische thermische Ausdehnungsverhalten des Baustoffs Beton ist für eine adäquate Berücksichtigung bei der Modellbildung es...
Building Information Modelling (BIM) hat den Digitalisierungsprozess in der gesamten Immobilienwirtschaft über alle Lebenszyklusphasen hinweg beschleunigt. Hinsichtlich der finanziellen Auswirkungen einzelner Lebenszyklusphasen macht die Betriebsphase den größten Teil der Lebenszykluskosten eines Gebäudes aus. Vor diesem ...
Sustainable aviation fuels provide the opportunity to reduce the aviation industry’s climate impact while avoiding a complete replacement of the current aircraft fleet. The European Union directs its member states to a gradual uptake of sustainable aviation fuel from 2 %vol. in 2025...
This paper uses a two-scale material modeling approach to investigate fatigue crack initiation and propagation of the material X10CrMoVNb9-1 (P91) under cyclic loading at room temperature. The Voronoi tessellation method was implemented to generate an artificial microstructure model at the micros...
Bacterial synthesis gas (syngas) fermentation offers a promising solution for the reduction of greenhouse gas emissions - the greatest challenge of today’s society. The substrate gas, which mainly consists of CO2, CO, and H2, represents an inexpensive feedstock originating from agricultural, ...
Erosion of metallic surfaces due to the permanent impact of high-speed water droplets is a significant concern in diverse industrial applications like turbine blades, among others. In the initial stage of water droplet erosion, there is an incubation regime with negligible mass loss...
This article presents RuPro, a new corpus resource of prosodically annotated speech by Russian heritage speakers in the U.S. and monolingually raised Russian speakers. The corpus contains data elicited in formal and informal communicative situations, by male/female and adolescent/adult speak...
The modeling of machining process characteristics and, in particular, of various cutting processes occupies a significant part of modern research. Determining the thermal characteristics in short hole drilling processes by numerical simulation is the object of the present study. For different...
Analyzing the cutting process characteristics opens up significant opportunities to improve various material machining processes. Numerical modeling is a well-established, powerful technique for determining various characteristics of cutting processes. The developed spatial finite element model of short hole...
La0.6Ca0.4Co1-xFexO3-d in its various compositions has proven to be an excellent CO2-resistant oxygen transport membrane that can be used in plasma-assisted CO2 conversion. With the goal of incorporating green hydrogen into the CO2 conversion process, this work takes a step further by i...
During the production of fiber-reinforced plastics using resin transfer molding (RTM), various characteristic defects and flaws can occur, such as fiber displacement and fiber waviness. Particularly in high-pressure RTM (HP-RTM), fiber misalignments are generated during infiltration by local peaks in&...
Additive manufacturing allows for the production of complex components using various types of materials such as plastics, metals and ceramics without the need for molding tools. In the field of high-performance polymers, semi-crystalline polymers such as polyetheretherketone (PEEK) or amorphous p...
Polymer concrete has proved to be advantageous in machine building for many years thanks to its excellent damping properties. Until now, its use was limited to machine beds due to its comparatively low tensile strength. Its use in moving structural components has not been poss...
Laser-based directed energy deposition using metal powder (DED-LB/M) offers great potential for a flexible production mainly defined by software. To exploit this potential, knowledge of the process parameters required to achieve a specific track geometry is essential. Existing analytical, numeric...
The Bouguer-Lambert-Beer (BLB) law serves as the fundamental basis for the spectrophotometric determination of pigment content in microalgae. Although it has been observed that the applicability of the BLB law is compromised by the light scattering effect in microalgae suspensions, in-depth ...
In today’s manufacturing landscape, Digital Twins play a pivotal role in optimising processes and deriving actionable insights that extend beyond on-site calculations. These dynamic representations of systems demand real-time data on the actual state of machinery, rather than static images depict...
Disassembly is a pivotal technology to enable the circularity of electric vehicle batteries through the application of circular economy strategies to extend the life cycle of battery components through solutions such as remanufacturng, repurposing, and efficient recycling, ultimately reintegrating gai...
Modern vehicles have increasing safety requirements and a need for reliable low-voltage power supply in their on-board power supply systems. Understanding the causes and probabilities of failures in a 12 V power supply is crucial. Field analyses of aged and failed 12 V lead ba...
