Abstract:Monitoring internal deformation and fracture of three-dimensional crystal structures under three-dimensional stress is very important. However, observing these phenomena solely by laboratory experiment is difficult. Several experimental results are available, but they are insufficient, since only the surfaces of the crystal structures could be observed. In an effort to obtain data beyond the limitations of laboratory experiment, we have been pursuing the development of computational simulation. This system enables us to analyze internal deformation and fracture of three-dimensional crystal structures with flaking and slipping on crystal grain boundaries. During this process we discovered the lack of useful visualization software, which is vital in evaluating the computational simulation results. In the present study we succeeded in developing visualization software which enables us to display and analyze internal deformation and fracture with flaking and slipping on crystal grain boundaries in an arbitrary cross section of three-dimensional crystal structures. The software development environment that we used is Direct3D 'Retained Mode' in Microsoft DirectX7. Key Words:Visualization, Fracture, Crystal structure, Grain boundary, Finite element spring model
