H. Irago et al., ASYMPTOTIC ANALYSIS OF HIGH-FREQUENCY MODES IN THIN RODS, Comptes rendus de l'Academie des sciences. Serie 1, Mathematique, 326(10), 1998, pp. 1255-1260
In this work, we show that a class of high frequency modes of the thre
e-dimensional linearized elasticity system in a thin rod and their ass
ociated eigenfunctions converge, as the thickness of the rods goes to
zero, and the limit model is a coupled one-dimensional problem giving
the classical equations for torsion and stretching vibrations. (C) Aca
