Abstract

Stress dispersion analysis of solid-fluid composites T. Katayama*, H. Yamamoto*, T. Nozato* & M. Mikf * Department of Mechanical Engineering, Doshisha University, Japan. * Hydraulic Excavator Development Centre, Shin Caterpillar Mitsubishi Ltd., Japan Abstract The purpose of this study in a long term is to apply biomimetic designed composites to artificial structures. To accomplish this, cancellous bone was modeled with hexagonal honeycomb. As cancellous bone is the solid-fluid composite, fluid was sealed in cells with thin films respectively. Subsequently, static indentation test was carried out, and then it was proven that films and internal fluid greatly effected on the load dispersion. In this paper, the finite element model was applied for the solid- fluid composites, and the effect only by the hydrostatic pressure was examined. As a result, internal fluid pressure which was controlled in specific direction effected on the load dispersion. 1 Introduction Living structure wh
