One of the research direction of Horst Lippmann during his whole scientific career was
devoted to the possibilities to explain complex material behavior by generalized continua …

The design of new technology for processing and manufacturing particulate products
requires understanding granular rheology over a broad range of conditions. Powders …

It has long been conjectured that, in three-dimensional turbulence, velocity modes at scales
larger than the forcing scale follow equilibrium dynamics. Recent numerical and …

We introduce a new rheological nonlinear model for some granular media such as
masonries. The latter may demonstrate a rather complex behaviour. In fact, considering a …

In the past decade, I have been teaching fluid mechanics from the fundamental to advanced
levels at Department of Civil Engineering at National Cheng Kung University in Taiwan, and …

Within the framework of the Cosserat continuum, the stability of a compressed circular rod
with a two-layer coating is studied. It is assumed that the coating layers were fixed to each …

We investigate the behavior of granular gases in the limit of small Knudsen number, that is,
very frequent collisions. We deal with the strongly inelastic case in one dimension of space …

We show the propagation of regularity, uniformly in time, for the scaled solutions of the
inelastic Maxwell model for small inelasticity. This result together with the weak convergence …

In this article, a numerical solution method for the finite-strain rate-independent Cosserat
theory of crystal plasticity is developed. Based on a time-incremental minimization problem …

The properties of a ultrasonic vibrated granular gas are investigated by using an event-
driven Molecular Dynamics simulation of inelastic hard spheres that are fluidized by a …
