High-speed Deformation / Fracture of Beam-structure (Al) by solid SPH

For suitable and developed utilization of engineering materials (for machines and structures), we should know essential and unknown properties of them.

Computational mechanics---we can grasp the information about properties or behavior of various materials by computer simulation based on precise mechanics and dynamics theory. Actually, modern design and manufacture of machine or structure are much owing to computational mechanics.

Nowadays, for materials engineering, much attention is paid to microscopic analysis (i.e. atomic-scale analysis) where the center methodology is Molecular Dynamics (MD) simulation. Nice linking between MD and traditional (computational, experimental) method for materials evaluation will open up and develop higher-level new scientific and industrial technologies concerning our engaging subject.

This group belongs to "Materials and Mechanics Laboratory", Department of Mechanical Engineering, Faculty of Engineering Science, Kansai University. We --- faculty staff, postgraduate, undergraduate--- all study, dicuss, publish, and make presentation about each themes and make collaborative work each other.

"Every efforts will always pay off, no effort will not."
