Flexural–torsional buckling of thin-walled composite box beams [PDF]

open access: yes, 2007
Buckling of an axially loaded thin-walled laminated composite is studied. A general analytical model applicable to the flexural, torsional and flexural–torsional buckling of a thin-walled composite box beam subjected to axial load is developed.

Homologous basic helix–loop–helix transcription factors induce distinct deformations of torsionally-stressed DNA: a potential transcription regulation mechanism

open access: yesQRB Discovery, 2022
Changing torsional restraints on DNA is essential for the regulation of transcription. Torsional stress, introduced by RNA polymerase, can propagate along chromatin facilitating topological transitions and modulating the specific binding of transcription

Study on the torsional movement of a reed valve in a rotary compressor

open access: yesAdvances in Mechanical Engineering, 2018
Torsional movement makes the motion of a reed valve very complex and unmanageable in a rotary compressor. However, there is little information on the torsional movement of the reed valve in comparison to the valve displacement and velocity in the ...
