The mechanical and numerical model
Pages 2

To generate a better basis for practical design a numerical method has been developed at the University of Karlsruhe under the author’s guidance to study the behaviour of granular bulk materials in silos during filling and discharging [3],[6],[10],[16], [18],[25],[28],[33],[37]. These investigations take into account all relevant phenomena such as realistic constitutive laws for the granular bulk material, density variations, the interaction between flexible silo walls, dynamic effects and probabilistic aspects.
