MECHANICAL MODELS: INSPIRATION AND EVOLUTION FROM MASS PARTICLE TO CONTINUUM

In response to the lack of comprehensive analysis of the relationship between different mechanical models in the professional curriculum system, this article elaborates on the evolution pathway from the basic mass particle model to the mass particle system, rigid bodies, continua, and multi-field coupling models, and explains the logical correlations between different models and the criteria that a "good" mechanical model must satisfy. This discussion helps readers grasp the holistic structure and detailed components of the mechanics knowledge system.
