Striation patterns in serrated blade stabs to cartilage
Forensic Science International, 2011Stab wounds were made in porcine cartilage with 13 serrated knives, amongst which 4 were drop-point and 9 straight-spine; 9 coarsely serrated, 3 finely serrated and 1 with mixed pattern serrations. The walls of the stab tracks were cast with dental impression material, and the casts photographed together with the knife blades for comparison.

Tool Mark Striations in Pig Skin Produced by Stabs From a Serrated Blade
American Journal of Forensic Medicine and Pathology, 2011Stab wounds produced by serrated blades are generally indistinguishable from stab wounds produced by non-serrated blades, except when visible tool mark striations are left on severed cartilage. Using a pig-skin experimental model, we explored the possibility that similar striations may be left in skin.

An Experimental Model of Tool Mark Striations by a Serrated Blade in Human Soft Tissues
American Journal of Forensic Medicine and Pathology, 2014Tool mark analysis is a method of matching a weapon with the injury it caused. In a homicidal stabbing using a serrated knife, a stab wound that involves a cartilage may leave striations from the serration points on the blade edge. Assessing tissue striations is a means of identifying the weapon as having a serrated blade.

Experimental study of wavy trailing edge serrations on flat rotor blades
INTER-NOISE and NOISE-CON Congress and Conference Proceedings, 2021A detailed experimental study is conducted to observe the effect of various parameters like wavelength, depth of serrations, and pitch angle on serrated blades' acoustic emissions at low speeds up to 2000 rpm. Experiments are conducted on flat blade rotors with sinusoidal serrations on the trailing edge of blades with different amplitudes and ...

Trailing edge noise prediction for rotating serrated blades
20th AIAA/CEAS Aeroacoustics Conference, 2014Serrations have been widely studied in the case of stationary blades, as an efficient method for reducing trailing edge noise. However, most of the problems involving trailing edge noise are related to rotating blades and it is not known how rotation affects the efficiency of serrations.

Experimental and Analytical Study of Micro-Serrations on Surgical Blades
Volume 3: Advanced Fabrication and Manufacturing; Emerging Technology Frontiers; Energy, Health and Water- Applications of Nano-, Micro- and Mini-Scale Devices; MEMS and NEMS; Technology Update Talks; Thermal Management Using Micro Channels, Jets, Sprays, 2015This paper reports on a study and application of laser ablation for machining of micro-serrations on surgical blades. The proposed concept is inspired by nature and mimics a mosquito’s maxilla, which is characterized by a number of serrations along its edge in order to painlessly penetrate human skin and tissue.

Prediction of broadband noise from rotating blade elements with serrated trailing edges
Physics of Fluids, 2022This paper conducts a theoretical investigation into the prediction of broadband trailing-edge noise for rotating serrated blades. Lyu's semi-analytical noise prediction model for isolated flat plates is extended to rotating blades using Schlinker and Amiet's approach and applied to three test applications including a wind turbine, a cooling fan, and ...
