An interactive simulation program for visualizing complex phenomena in solids

Abstract In the present article an interactive simulation program illustrating grain boundary and fracture phenomena in solids is described. The dynamical behaviour of a two-dimensional Lennard-Jones model system under stress, with either a grain boundary or an initial crack, is simulated through a molecular dynamics algorithm. All parameters defining the system and the dynamical load are set through a graphical user interface. A run-time representation of the system is displayed on a graphics window,... Title of program: Fracture Catalogue Id: ADKS_v1_0 Nature of problem In a typical research activity involving simulations of complex physical systems, one is often faced with a 'research loop', which may be loosely described as follows: definition of input data; running of a simulation, outputting data to a storage disk; post-processing of the accumulated data for extracting relevant information with the eventual aid of graphics and numerical packages; definition of new input parameters and, closing the loop, starting a new simulation run. Advances in computer ha ...
