From 28th to 30th June 2022, as part of the cooperation between the Institute of Applied Mechanics of the Poznan University of Technology and the Chair of Mechanics and Machine Dynamics of BTU Cottbus Senftenberg, a course was held as part of the university alliance EUNICE. The thematic focus was selected chapters of the theory of applied mechanics. The course was offered to students of mechanical engineering and consisted of lectures and practical application with the finite element software Ansys. The lectures were given by Prof. Dr.-Ing. Matthias Ziegenhorn from BTU Cottbus Senftenberg. The practical part using the Ansys software was led by research assistant Philipp Maasch. At the end of the course, the students received certificates. The course is part of a long-term cooperation between Poznan University of Technology and BTU Cottbus Senftenberg in the field of mechanics and biomedical engineering.
Under the direction of visiting scientists Dr. Irina Smolina and Dr. Andrzej Pawlak, second place was won in the poster competition at the 15th International Conference Computer Aided Engineering. The research focused on creating material models for additively manufactured metals.
Together with the research group led by Prof. Adelung at Christian Albrechts University in Kiel, a jointly planned DFG project was approved. The aim of the project is to develop and investigate multi-scale, functional interpenetration composite structures whose physical properties can be changed in a controlled and reversible manner by applying an electrical stimulus. The concept is based on microstructured polymers that are permeated by a disordered network of interconnected micro-channels. By selectively coating the microchannel walls with a thin layer of conductive nanomaterials, such as graphene, electrically conductive interpenetrating composites are created that are characterized by an extremely low volume fraction of conductive material. Thereby, the mechanical properties of the matrix material remain virtually unchanged. Simultaneously, this functionalization enables rapid heating of the composite by Joule heating.
As part of a joint agreement between the Poznań University of Technology and BTU Cottbus-Senftenberg, we offer joint doctorates between the partner universities. The fields of mechanical engineering and biomedical engineering are supported. Details on the topics can be found here and further information can be found here.
The Colloquium on Applied Mechanics, Materials, Design and Biomedical Engineering was held this year at the Poznan University of Technology. Organized by the Faculty of Mechanical Engineering and the chair of Engineering mechanics and machine dynamics of BTU Cottbus Senftenberg, the event is a continuation of the intensive cooperation between German and Polish scientists. During the colloquium, topics in the field of additive manufacturing, hybrid electric propulsion systems for climate-neutral flying and biomedical engineering were presented by PhD students and scientists from both universities.
Dr.-Ing. Irina Smolina (Fellow in the Fellowship program at BTU) recently received a project grant entitled "New generation aluminum-based alloys processed by laser additive manufacturing for industrial applications" (AddAluMat) under the "Lider" program of the National Center for Research and Development (Poland). The AddAluMat project aims to develop a technology for processing functional aluminum alloys (5xxx series) using laser powder bed fusion (LPBF) technology and the possible use of additives for aluminum alloy powders to obtain a uniform structure of processed objects used in a wide range of industrial applications. A selected demonstration part from an established industry (including automotive and/or marine) will be subjected to topological optimization and fabricated by the LPBF process using a developed alloy. The "Lider" program of the National Center for Research and Development is aimed at young scientists (up to seven years after their PhD) from various scientific and research institutions and from industry, regardless of their passport and citizenship. The condition is that they conduct research in Poland. (Photo - Press-materials of NCBR)
Dr. Irina Smolina
Dr. Irina Smolina works at Wrocław University of Science and Technology (WUST, Wroclaw, Poland) in the Department of Laser Technologies, Automation and Production Management and the Center for Advanced Manufacturing Technologies (CAMT, Wroclaw, Poland). During the BTU Flagship Fellowship program, Irina will conduct the project "Influence of aluminum alloy powder reuse on the quality and mechanical properties of L-PBF coated samples". This research project will be conducted at Brandenburg University of Technology (BTU) and Wroclaw University of Science and Technology (WUST). The aluminum alloy research specimens will be fabricated using L-PBF (Laser Powder Bed Fusion) technology at CAMT, while at BTU-Cottbus-Seftenberg Dr.-Ing.

In the national aviation research program (LuFo VI), an efficient certification process for additive manufacturing as a technology in aviation is being developed and qualified with an interdisciplinary consortium. For this purpose, integrated solutions for quality assurance and for component and process certification must be developed.
The aim of the project is to develop standards for additive manufacturing further and to establish a self-learning Big Data and AI-based platform for digital testing and certification processes in additive manufacturing. The work of the BTU - research group is focused on joints between existing construction and additively manufactured components.
The project will be realized in the period from 2021 to 2025.

In order to improve the design and mechanical simulation of repaired components and spare parts, particularly with regard to strength properties and service life, a systematic methodology is being developed that allows application-specific material parameters to be determined using suitable testing methods based on given application requirements (load cases, environmental conditions) and process parameters.
The solution forms a complete process chain from damage analysis, digitization of manufacturing documents or generation of new design documents, selection of the manufacturing or repair process and testing of the component to certification and delivery.
The project will be realized in the period from 2021 to 2024.
