Dual clearance squeeze film damper for high load conditions [PDF]
Squeeze film dampers are widely used to control vibrations in aircraft turbine engines and other rotating machinery. However, if shaft unbalance rises appreciably above the design value (e.g., due to a turbine blade loss), a conventional squeeze film ...

Functionally graded Ag/Fe3O4‐loaded PAN nanofiber interlayers for improved mechanical performance and EMI attenuation in GFRP laminates. ABSTRACT Functionally graded Ag/Fe3O4‐loaded polyacrylonitrile (PAN) nanofiber interlayers were placed between selected glass fabric plies to improve interlaminar damage resistance in glass fiber‐reinforced polymer ...

Instability of an intershaft squeeze film damper in a two-spool rotor dynamics simulator [PDF]
An instability associated with an intershaft squeeze film damper is described. The squeeze film is located between the intershaft bearing outer race and the low-speed shaft of a five-bearing, two-spool test rig.

Dental Microwear Texture Analysis on Radular Teeth
3D microwear textures reveal how gastropod radular teeth respond to controlled abrasive contact. Distinct surface signatures distinguish regular abrasion from fracture‐dominated material removal, showing how mineralized coatings, fibrous cores, and substrate properties jointly shape wear and failure in a biological scraping interface.

High‐Stress Si3N4 Reflective Membranes Monolithically Integrated With Cavity Bragg Mirrors
Silicon nitride membranes are record‐breaking mechanical sensors, yet their delicate fabrication and alignment into precision optical cavities have confined them to the laboratory. A monolithic process directly integrates suspended high‐stress Si3N4${\rm Si}_{3}{\rm N}_4$ membranes onto Bragg mirrors, forming self‐aligned optomechanical cavities in ...
