On the torsional energy of torus knots under infinitesimal bending
Analele Stiintifice ale Universitatii Ovidius Constanta: Seria Matematica, 2023 The article deals with the infinitesimal bending theory application to the knots theory. The impact of infinitesimal bending on the torsional energy at torus knots is considered, and the results show that it is not stationary under infinitesimal bending.

The impact of tibial torsion measurements on gait analysis kinematics
Acta Ortopédica Brasileira, 2014 To measure and compare tibial torsion values as assessed by goniometry and three-dimensional kinematics. In addition, the impact of each one of these measurements on kinematic and kinetic results for normal gait was determined.Twenty-three healthy and fully ambulatory patients were assessed, 11 women and 12 men, from 20 to 40 years old.

On triply coupled vibrations of axially loaded thin-walled composite beams [PDF]
, 2010 Free vibration of axially loaded thin-walled composite beams with arbitrary lay-ups is presented. This model is based on the classical lamination theory, and accounts for all the structural coupling coming from material anisotropy.

The Stress Singularity in a Stepped Bar Under Impact Torsion
JSME international journal. Ser. 1, Solid mechanics, strength of materials, 1989 An impact torsion problem for a steppedbar composed of two semi-infinite bars bonded completely at each end is investigated. A stress singularity occurs at the corner of the bars. Therefore the stress analysis proceeds considering this stress singularity by making use of the series expansion technique, and the problems are reduced to an infinite set of
