“…In the literature there are numerical results obtained via refined finite element codes and experimental studies on the subject. Some of these, regarding a frame shaped spatial beam, are in [Kim and Kim 2000;Kim et al 2001;Gu and Chan 2005;Teh 2005]. Still, to the authors' knowledge, an analytical study derived from a geometrically exact model is not available and the results obtained here could be of importance in applications.…”

“…W praca [3] rozwiązano zagadnienie drgań wymuszonych aperiodycznie, niepryzmatycznej, cienkościennej o liniowo zmiennej wysokości belki wspornikowej. Autorzy pracy [4] sformułowali cienkościenny element skończony, który następnie wykorzystali do rozwiązania problemu stateczności oraz zagadnienia drgań swobodnych.…”

“…The rotation tensor T( n θ) results the natural rotation vector n θ according to the procedure given in Equations (11)(12)(13)(14)(15)(16)(17)(18)(19) to extract the rotation vector from the rotation tensor. The components of the rotation vectors n θ i for a node i give the natural rotations on the node.…”

“…Kim et al [15][16][17] and Hsiao et al [18][19][20][21] also employed this condition to define the natural deformation. Let us define the natural torsions as n θ i1 and n θ j1 for each node, which is a rotation about the 1-axis of the reference coordinate system.…”
