Effect of Surface Roughness on Contact Pressure of Static Seals (Sealing Characteristics of Knife-Edge Seals).

open access: yesJSME international journal. Ser. 3, Vibration, control engineering, engineering for industry, 1992
In this paper, the sealing mechanism of knife-edge seals was explained and a new type of knife edge was developed. The following results were obtained: (1) The sealing mechanism of knife-edge seals was divided into three types according to the width of the flat area on the apex of the knife edge: (a) the penetration type, (b) the indentation type, and (

Experimental Characterization of Mycelium‐Based Composites Under Multiple Loading Conditions

open access: yesAdvanced Engineering Materials, EarlyView.
This study examines the mechanical response of mycelium‐based composites under compression, shear, and tension using mechanical testing and imaging methods. The comparison between unpressed and hot‐pressed specimens shows that hot pressing is associated with higher compression and shear stiffnesses.
