Abstract

This paper deals with the investigation of bulk material filled silos under seismic excitation. The described numerical model for a silo consists of three components, namely the granular material, an interface element between the granular material and the silo wall and the silo itself. The bulk material behaviour is described in four different ways: by the classical hypoplasticity theory, by two special versions of it which use time history functions and finally by the intergranular strain approach. The dynamic behaviour as described by these four different material laws is presented, as well as comparisons of the numerical results with experimental data.

Granular Material Behaviour under Dynamic Excitation

San Diego, California

This paper deals with the investigation of bulk material filled silos under seismic excitation. The described numerical model for a silo consists of three components, namely the granular material, an interface element between the granular material and the silo wall and the silo itself. The bulk material behaviour is described in four different ways: by the classical hypoplasticity theory, by two special versions of it which use time history functions and finally by the intergranular strain approach. The dynamic behaviour as described by these four different material laws is presented, as well as comparisons of the numerical results with experimental data.
