On isochronous dynamics.
We propose a systematic approach to the problem of isochronicity in Hamiltonian dynamics. In particular, we present an explicit neccesary and sufficient condition for isochronicity in the case of 1DOF in terms of the Taylor expansion of the Hamiltonian function.

Bio: Moubin Liu is the Vice Dean and a Professor of the College of Engineering, Peking University. His areas of interest include computational fluid dynamics and computational fluid-structures interactions, using particle-based methods including SPH, and particle-grid coupling approaches including SPH-FEM, DEM-CFD and etc. |

Smoothed particle hydrodynamics (SPH) for modeling fluid-structure interactions.
SPH, as a truly Lagrangian and meshfree particle method, is very attractive in modeling fluid-structure interaction (FSI) problems. This talk reports some recent developments of SPH method in modeling FSI problems with rigid, elastic and flexible structures, with granular materials, and with extremely intensive loadings.
The meeting will be held in the form of a webinar on the Zoom platform.
Pre-registration for the event is not required.
