Description

technical field [0001] The invention belongs to the technical field of computer modeling, and in particular relates to a method, system and medium for simulating blast injury of human maxillofacial area and biomechanics. Background technique [0002] At present, explosive weapons are widely used in modern warfare. Due to the lack of protection of the maxillofacial area, the proportion of explosive injuries in the maxillofacial area is relatively high, and the treatment of explosive injuries in the maxillofacial area is difficult, and the injury and death rates are high. Therefore, the establishment of human maxillofacial The focus of maxillofacial combat trauma research is to establish a model of facial soft and hard tissue blast injury and systematically analyze the mechanism, injury characteristics, protection and treatment of maxillofacial blast injury. Three-dimensional finite element method (FEM) can analyze complex mechanical changes between objects and inside objects,...
