Existence And Stability

One of the least studied universal deformations of incompressible nonlinear elasticity, namely the straightening of a sector of a circular cylinder into a rectangular block, is revisited here and, in particular, issues of existence and stability are addressed. Particular attention is paid to the system of forces required to sustain the large static deformation, including by the application of end couples. The influence of geometric parameters and constitutive models on the appearance of wrinkles on the compressed face of the block is also studied. Different numerical methods for solving the incremental stability problem are compared and it is found that the impedance matrix method, based on the resolution of a matrix Riccati differential equation, is the more precise.

Phonon Properties

This paper presents the phonon properties of Fibonacci chains in the harmonic approximation theoretically. Using the transfer matrix method, we investigate the influence of the atom masses on the phonon spectra of quasiperiodic chains. Our calculations show that the atom masses determine the widths and positions of gaps. Moreover, the phonon spectra of Fibonacci chains made by two atoms are self-similar in the high-frequency regions.
