Guangqi Chen教授の研究室では、破壊・大変形を伴う固体の力学挙動を高精度に解析するための新しい数値解析手法の開発に取り組んでいます。特に、メッシュフリーな手法としてのManifold Method（MM）や、不連続変位解析法（DDA）を応用し、地下工事における岩盤バーストの予測・評価に貢献しています。これらの手法は、大変形や破壊挙動を高精度に再現できる点で、伝統的な有限要素法に比べて優れた性能を示します。

The Manifold Method of Material Analysis (MM) with high-order displacement functions has been derived based on triangular meshes for the requirement of high accurate calculations from practical applications. The matrices of equilibrium equations for the second-order MM have been given in detail for program coding. The derivation of the method is made by means of approximation theory and very few new mathematical concepts are used in this paper. So, it may be understood by most engineering resear
A rock burst can cause a serious disaster. For the mitigation of rock burst-induced disaster, the possibility assessment of a rock burst for an underground excavation is a key undertaking and also a great challenge because rock burst failure involves a dynamic and large deformation process. In this paper, a numerical simulation method of rock burst using discontinuous deformation analysis (DDA) is proposed by showing the advantage of DDA in handling the large deformation of this dynamic process.
