Acoustic field characterization of medical array transducers based on unfocused transmits and single-plane hydrophone measurements

Marhenke, Torben; Sanabria, Sergio J.; Chintada, Bhaskara Rao; Furrer, Roman; Neuenschwander, Jürg; Goksel, Orcun (Basel : MDPI AG, 2019)

Medical ultrasonic arrays are typically characterized in controlled water baths using measurements by a hydrophone, which can be translated with a positioning stage. Characterization of 3D acoustic fields conventionally ...
Correction: Mechanical properties of femoral trabecular bone in dogs

Pressel, Thomas; Bouguecha, Anas; Vogt, Ute; Meyer-Lindenberg, Andrea; Behrens, Bernd-Arno; Nolte, Ingo; Windhagen, Henning (London : BioMed Central Ltd., 2005)

After the publication of this work [1], we became aware of the fact that the frequency of the ultrasound transmitter that we used for determining the elastic moduli of the trabecular bone specimens was not correctly ...
Influence of the ultrasonic vibration amplitude on the melt pool dynamics and the weld shape of laser beam welded EN AW-6082 utilizing a new excitation system for laser beam welding

Ohrdes, H.; Nothdurft, S.; Nowroth, C.; Grajczak, J.; Twiefel, J.; Hermsdorf, J.; Kaierle, S.; Wallaschek, J. (Berlin : Springer, 2021)

Laser beam welding is a commonly used technology for joining similar and dissimilar materials. In order to improve the mechanical properties of the weld, the introduction of ultrasonic vibration into the weld zone has been ...
Influence of ultrasound on pore and crack formation in laser beam welding of nickel-base alloy round bars

Grajczak, Jan; Nowroth, Christian; Nothdurft, Sarah; Hermsdorf, Jörg; Twiefel, Jens; Wallaschek, Jörg; Kaierle, Stefan (Basel : MDPI AG, 2020)

Welding by laser beam is a method for creating deep and narrow welds with low influence on the surrounding material. Nevertheless, the microstructure and mechanical properties change, and highly alloyed materials are prone ...
Investigation of the high frequency dynamic-mechanical properties of polymer systems using ultrasonic longitudinal waves

Oprisoni, Cristian Alexandru (Hannover : Gottfried Wilhelm Leibniz Universität Hannover, 2011)

[no abstract]
Mechanical properties of femoral trabecular bone in dogs

Pressel, Thomas; Bouguecha, Anas; Vogt, Ute; Meyer-Lindenberg, Andrea; Behrens, Bernd-Arno; Nolte, Ingo; Windhagen, Henning (London : BioMed Central Ltd., 2005)

Background: Studying mechanical properties of canine trabecular bone is important for a better understanding of fracture mechanics or bone disorders and is also needed for numerical simulation of canine femora. No detailed ...
Visualization of dynamic stress conditions in elastic solids utilizing high frequency stroboscopic LED arrays

Shi, Jian; Ohrdes, Hendrik; Weinstein, Michael; Twiefel, Jens (Bellingham, Wash. : SPIE, 2019)

Ultrasonic mechanical vibrations in solids are widely used in non-destructive testing, and high-power applications such as ultrasonic welding or soldering. The visualization of ultrasonic wave propagation in transparent ...
