Sign Up to like & getrecommendations! Published in 2021 at "European Archives of Oto-Rhino-Laryngology"
DOI: 10.1007/s00405-020-06511-9
Abstract: Several authors have reported their experience with the punch technique as compared to open surgical methods for bone-anchored hearing implants (BAHI). However, no study has attempted to aggregate current evidence. We aimed to compare post-operative… read more here.

DOI: 10.1016/j.ijmecsci.2018.02.024
Abstract: Abstract The most common failure criterion in sheet metal forming operations is the forming limit diagram (FLD). Typically, the FLD is evaluated with the Nakajima test, which is a stretch forming-based test that allows the… read more here.

DOI: 10.1016/j.jmps.2018.06.001
Abstract: Abstract The penetration of unidirectional (UD) and [0o/90o] cross-ply ultra-high molecular weight polyethylene fibre composites by sharp-tipped cylindrical punches has been investigated. While the measured penetration pressure for both composite types increased with decreasing punch… read more here.
