Summary: This paper presents a novel approach to determine material model parameters inversely from FE-machining simulations using the Downhill-Simplex-Algorithm. An effect study was conducted to investigate the influence of the initial simplex, the boundary conditions, and the underlying parameters of the algorithm. The validated procedure has been extended to consider multiple cutting conditions and an adaptive step-size has been implemented, resulting in a robust and systematic method for determining material model parameters inversely from the machining process.

Summary: The study characterizes the electrical contact resistance of copper contacts for resistance welding, showing the significant influence of contact pressure, temperature, oxide layer thickness, and surface roughness on the specific electrical contact resistance. Results indicate a decrease in SECR with higher mechanical load on the contact and a more complex behavior with increased contact temperature. The variation of oxide layer thickness and surface roughness has a strong influence on the resulting SECR, showing a strong coupling between these two surface parameters.

Summary: The effects of silver content, sintering temperature, sintering time, and compaction pressure on the properties of contacts were studied. It was found that increasing the silver content and the time and temperature of the sintering process increased the oxidation of copper. Galvanic corrosion and the Kirkendall effect between copper and silver resulted in the formation of microvoids around copper particles, facilitating the copper oxidation. The apparent bulk density remained relatively constant with increasing sintering temperature up to 700 degrees C, but decreased sharply at higher temperatures. Increasing the sintering time up to 60 minutes increased the apparent bulk density, while longer times decreased it. Compaction pressure did not significantly affect the apparent bulk density.

Summary: Copper oxide is widely studied in various fields such as wastewater decontamination, hydrogen production, solar cell production, and sensor fabrication. A new method of thermal oxidation was developed to grow electrical insolate Cu2O films on copper surfaces in an air atmosphere. These films have polyhedral architectures of approximately 1.4 μm thickness and are electrically insulating. A novel copper resistive furnace was built using the copper oxide film as an electrical insulator, resulting in higher temperatures and faster response times compared to traditional furnaces using ceramic insulation.

Summary: The study found that depressed patients with both chronic pain and self-harm behaviors showed higher sensitivity in pressure pain thresholds. Hopelessness was identified as a mediator between depression severity and pain sensitivity. The findings suggest a comprehensive approach including mental health services and pain control is needed for depressed patients with comorbid chronic pain and nonsuicidal self-harm behaviors to achieve effective outcomes.

Summary: This study prepared high-strength ceramic lightweight aggregates from oil-based drill cutting pyrolysis residues and examined their formation mechanism and expansion during sintering. It was found that the presence of Al2O3 suppressed the melting process and increased the particle strength. The glass phase also contributed toward the high strength of ceramic materials by adhering to crystal grains and forming a concrete-like structure.
