Experimental Measurement Method and Evaluation of an Analytical Approach for Sound Conduction through Multiple Clinched Sheets

Engineering Proceedings, 2022
The conduction of structure-borne sound through joints causes energy dissipation. The sound reduction index describes this energy loss as a level decrease in the particle velocity across series-connected damping elements for which the superposition ...

Deep Drawing with Macro Structured for an Environmentally Friendly Process

Journal of Machine Engineering, 2020
The efficient use of resources are becoming more important due to economic and environmental requirements. In widely used forming processes like deep drawing an avoidance of lubricants – namely dry deep drawing – is a key factor for saving resources.
