Assuming the existence of quasi-particles, which is proposed as an idea of simplification technique, we can reduce the number of particles to be treated in a given system. This simplification can enable us to perform computer simulations more easily when we analyze the behavior of many particles by the molecular dynamics method. After an appropriate potential function to be applied to the quasi-particle was formulated successfully, we were able to develop a computer code QPC (quasi-particle collision simulation) based on the quasi-particles. Dynamic-behavior analysis of the breakup process of a model particle composed of quasi-particles was performed using the QPC code from a microscopic point of view. The findings are summarized in a two-dimensional map of three regions representing an agglomeration process of collided particles, a particle growth process, and also a particle breakup process after a head-on collision took place between the model particles.
