How-ever, the reliable and cost-efficient joining of aluminium components remains a challenge. Mechanical joining methods, such as riveting, are frequently used in the automotive and aerospace construction industries. Rivets are made from heat-treated steels. Compared to steel, the use of aluminium materials for fasten-ers offers several advantages in terms of joining properties, particularly in terms of recyclability, corrosion resistance and reduced weight of the joined structure. Additionally, the manufacturing process is shorter since aluminium fasteners do not require coating. However, aluminium rivets can often not be used due to the insufficient mechanical strength of the fastener material in relation to the joining component materials.\r\nThis study systematically investigates the requirements for using solid alu-minium self-piercing rivets. The influence of rivet geometry adjustments on the joint quality is analysed using numerical simulation. The results are used to derive and evaluate an optimised rivet geometry for joining pure aluminium sheets. On this basis, solid self-drilling rivets with optimised geometry are manufactured from particle-reinforced aluminium produced in a continuous extrusion process by machining. The integration of particles increases the material’s strength. Exper-imental tests are conducted to evaluate the use of optimised solid self-piercing rivets. The quality-relevant parameters are determined and evaluated based on macrographs of the joints." author: - first_name: Steffen full_name: Koch, Steffen last_name: Koch - first_name: Joshua full_name: Weber, Joshua last_name: Weber - first_name: Gerson full_name: Meschut, Gerson last_name: Meschut - first_name: Claudia full_name: Stadelmann, Claudia last_name: Stadelmann - first_name: Wolfgang full_name: Böhm, Wolfgang last_name: Böhm - first_name: Marion full_name: Merklein, Marion last_name: Merklein citation: ama: 'Koch S, Weber J, Meschut G, Stadelmann C, Böhm W, Merklein M.

In many cases, the efficiency of the melting process acts as the primary throughput-limiting factor. If the material melts too late in the process, it may not be sufficiently mixed, resulting in substandard product quality. Accurate prediction of the melting process is therefore essential for efficient and cost-effective machine design. A practical method for engineers is the modeling of the melting process using mathematical–physical models that can be solved without complex numerical methods. These models enable rapid calculations while still providing sufficient predictive accuracy. This study revisits the modified Tadmor model by Potente, which describes the melting process and predicts the delay-zone length, extending from the hopper front edge to the point of melt pool formation. Based on extensive experimental investigations, this model is adapted by redefining the flow temperatures at the phase boundary and accounting for surface porosity at the beginning of the melting zone. Additionally, the effect of variable solid bed dynamics on model accuracy is examined. Significant model improvements were achieved by accounting for reduced heat flow into the solid bed due to the porous surface structure in the solid conveying zone, along with a new assumption for the flow temperature at the phase boundary between the solid bed and melt film. author: - first_name: Volker full_name: Schöppner, Volker id: '20530' last_name: Schöppner - first_name: Florian full_name: Brüning, Florian id: '72920' last_name: Brüning - first_name: Felix full_name: Knaup, Felix id: '45124' last_name: Knaup citation: ama: Schöppner V, Brüning F, Knaup F.
