• 論文の詳細を見る

• In this paper a method of solution is developed for the two-dimensional problems on the compression of granular materials by applying the finite element method to the fundamental equations of the statics for granular materials derived by T.Nagao. This method has been applied to the compression of granular materials in a square box with one of the patterns in several kinds of dimensions set at its bottom. The results are compared with those obtained from the compression tests of silica sands, and the theoretical stress values are found to agree fairly well with the experimental ones. The stress state in the so-called"Elastic Zone"can be made clear by using this method; analysis of this problem has been considered intractable by the existing methods.
