講義概要

Theory of plasticity is used to describe mechanical behaviors of granular materials in many engineering and industrial applications. Sand, agricultural grains and chemical particles are granule in nature. Therefore, inelastic responses of granular media are important in construction, storage and process. This course provides the advanced subject in Geomechanics and Powder mechanics to understand load transfer mechanisms and predict stress distributions. Analytical methods based on a framework of continuum mechanics focusing on arching effect are given with applications to retaining wall, slope, dune, silo and hopper.

講義の目的

This lecture provides fundamental concepts of arching effect in granular media to those who are interested in design and analysis of the retained structures for appliations in Civil Engineering, Mechanical Engineering and Chemical Engineering.

担当教員の一言

The content of this course was developed in 2009 after collecting knowledge about soil arching from many books and papers. I found that the topic on arch action is suitable to teach in a graduate program of the International Development Engineering Department because its broaden applications can cover multidiscipline of Civil Engineering, Mechanical Engineering and Chemical Engineering. Three years have been spent to achieve experimentally realizable theories with actual engineering practice to open-pit mining.
