Our results do not only reveal a substantial IBG for most stated intentions, but also show their limits in serving as a good predictor for realized actions later. Moreover, the IBG itself can hardly be explained by observable household data characteristics. While we do find some similarities in explanatory variables affecting both intentions and implementations, these variables provide only little insights into the actual levels of implemented actions. In line with regret theory, the IBG in our data can be partly explained by anticipated regret caused by a feeling of having invested in vain in cases where adaptation measures are installed, but extreme weather events do not occur for the time being. Our results are informative for adaptation-related communication campaigns and public policy interventions, especially in the aftermath of natural disasters."}],"user_id":"98922","_id":"58473","language":[{"iso":"eng"}],"article_type":"original","keyword":["Intention-behavior gap","Adaptation","Climate Change","Flooding","Heat"]},{"type":"dissertation","status":"public","abstract":[{"text":"Diese Arbeit behandelt die Modellierung und Optimierung von mit Phasenwechselmaterialien (PCM) ausgestatteten, energietechnischen Komponenten anhand zweier Fallstudien.

PCM are materials whose phase change characteristics during melting and solidification are utilized for heating and cooling purposes. The theoretical foundations of heat transfer problems involving phase change, along with the relevant numerical solution methods, are discussed. A phase change model is presented, which was validated against analytical solutions and applied in the case studies. For both case studies, a review of the state of the art is provided, followed by the formulation of specific research problems. The first case study investigated PCM-enhanced photovoltaic modules, while the second focused on packed bed latent heat storages (PBLHS) utilizing non-spherical PCM capsules. Thermal models were developed for both systems and validated with good accuracy against experimental data. These models were employed in parameter studies to identify optimized system configurations. The presented results demonstrate that a PCM heat sink with sufficient thickness and thermal conductivity can significantly improve the efficiency and lifespan of photovoltaic modules. Furthermore, PCM capsules with both high packing density and surface area increase the volume-specific storage capacity and thermal power output of PBLHS.","lang":"eng"}],"user_id":"66520","department":[{"_id":"9"}],"_id":"59239","language":[{"iso":"eng"}],"keyword":["Heat transfer","PCM","numerical simulation","renewable energy","heat storage"],"publication_status":"published","citation":{"bibtex":"@book{Grabo_2025, place={Paderborn}, title={Modeling and optimization of energy system components equipped with phase change materials}, DOI={<a href=\"https://doi.org/10.17619/UNIPB/1-2199\">10.17619/UNIPB/1-2199</a>}, author={Grabo, Matti}, year={2025} }","short":"M.

For this reason, this study focuses on the development of a new forming technology for Ti-6Al-4V sheet metal. It is based on combination of solution treatment by resistive heating with rapid tool-based quenching and subsequent annealing. This new “TISTRAQ” process is comparable with press-hardening already known for steels and hot die quenching known for aluminium alloys. One of the main influencing factors for this process is the heat transfer coefficient (HTC). It is an important driver for adjustment of basic parameters, as selection of tool material or the forming speed but also plays an important role while elaborating temperature distribution in the numerical model. Therefore, a new and unique test rig was developed to determine the HTC and to perform tool-based heat treatment at specimen level under laboratory conditions. The test rig was used to investigate the influence of the titanium-tool-lubricant system on HTC and cooling rate. Further the effect of heat treatment in the test rig and tool-based quenching on microstructure and mechanical properties was studied. To improve the prediction of the temperature distribution of the titanium during cooling, the HTC was integrated into the numerical process simulation","lang":"eng"}],"status":"public","type":"conference","publication":"IOM3.

For this purpose, three series of tests were performed. In the first series of tests, the influence of heat treatment up to 340 °C on the mechanical properties of an age-hardenable AlMgSi alloy was investigated. Holding time and temperature were varied and the material strength was evaluated by tensile and hardness tests. Two strength-increasing and two strength-reducing heat treatment parameters were identified. In the second series of tests, selected heat treatment parameters were applied to a larger number of specimens and the joint strength was investigated by shear and head tensile tests. In the shear tensile test, mainly the properties of the punch-side material have an influence on the resulting joint strength. A change in strength of the die-side material can be neglected. In contrast, the properties of both sheets are important in the head tensile test. The strength of the joint will only increase if the strength of both sheets is increased. In general, a strength increasing heat treatment resulted in higher joint strength. In the third series of tests, the factor of punch displacement was considered, which was demonstrated to directly influence the formation of the clinched joint geometry.","lang":"eng"}],"type":"journal_article","publication":"Journal of Advanced Joining Processes","doi":"10.1016/j.jajp.2024.100263","title":"Influence of the material properties on the clinching process and the resulting load-bearing capacity of the joint","date_created":"2025-06-23T07:54:23Z","author":[{"first_name":"Christian","full_name":"Steinfelder, Christian","last_name":"Steinfelder"},{"first_name":"Dennis","last_name":"Rempel","full_name":"Rempel, Dennis"},{"last_name":"Brosius","full_name":"Brosius, Alexander","first_name":"Alexander"}],"volume":10,"date_updated":"2025-06-23T07:57:53Z","publisher":"Elsevier BV","citation":{"apa":"Steinfelder, C., Rempel, D., &#38; Brosius, A.

To achieve the same process stability when using copper wire instead of aluminum wire a profound understanding of the bonding process is needed. Due to the higher hardness of copper compared to aluminum wire it is more difficult to approach the surfaces of wire and substrate to a level where van der Waals forces are able to arise between atoms. Also, enough friction energy referred to the total contact area has to be generated to activate the surfaces. Therefore, a friction model is used to simulate the joining process. This model calculates the resulting energy of partial areas in the contact surface and provides information about the adhesion process of each area. The focus here is on the arising of micro joints in the contact area depending on the location in the contact and time. To validate the model, different touchdown forces are used to vary the initial contact areas of wire and substrate. Additionally, a piezoelectric tri-axial force sensor is built up to identify the known phases of pre-deforming, cleaning, adhering and diffusing for the real bonding process to map with the model. Test substrates as DBC and copper plate are used to show the different formations of a wedge bond connection due to hardness and reaction propensity. The experiments were done by using 500 $\\mu$m copper wire and a standard V-groove tool.","lang":"eng"}],"publication":"Electronic Components and Technology Conference (ECTC), 2014 IEEE 64th","type":"conference","language":[{"iso":"eng"}],"keyword":["adhesion","circuit reliability","deformation","diffusion","fatigue cracks","friction","interconnections","lead bonding","van der Waals forces","Cu","adhering process","adhesion process","ampacity improvement","bond quality improvement","cleaning process","diffusing process","fatigue fracture failure","friction energy","friction model","heat dissipation","mechanical strength","piezoelectric triaxial force sensor","predeforming process","size 500 mum","total contact area","van der Waals forces","wedge copper wire bonding","Bonding","Copper","Finite element analysis","Force","Friction","Substrates","Wires"],"department":[{"_id":"151"}],"user_id":"55222","_id":"9868","page":"1549-1555","citation":{"ama":"Althoff S, Neuhaus J, Hemsel T, Sextro W.
