DOI: 10.1016/j.jfluidstructs.2018.07.006
Abstract: Abstract In this paper, an underwater vibration model is developed to depict the dynamic characteristic of V-shaped beams for both small and finite amplitude vibrations by considering the fluid–structure interactions between the complicated geometry and… read more here.

DOI: 10.1039/d2sm01488b
Abstract: Here we use simulations and theory to show that, close to the jamming point, an arbitrary initial distortion of a granular media induces the formation of forward and backward non-linear finite amplitude waves. There are… read more here.

DOI: 10.1103/physrevc.103.014306
Abstract: The finite-amplitude method is used in solving the local quasiparticle random-phase approximation to calculate the collective inertia along a fission path obtained by the constrained Hartree-Fock-Bogoliubov method with a Skyrme energy-density functional. The collective inertia… read more here.

DOI: 10.1121/1.4989276
Abstract: In this paper we compare the two most popular indicators of nonlinearity, namely, the Gol’dberg number [Sov. Phys. Acoust. 2, 346-350 (1956)] and the Morfey-Howell Q/S [AIAA J. 19, 986-992 (1981)] for the case of… read more here.

DOI: 10.3390/e21121219
Abstract: Using a Lyapunov type functional constructed on the basis of thermodynamical arguments, we investigate the finite amplitude stability of internal steady flows of viscoelastic fluids described by the Giesekus model. Using the functional, we derive… read more here.
