Material appearance state display method and system

Abstract

The invention provides a material appearance state display method and system, and the method comprises the steps: creating a texture library which can be called by analog simulation software and is used for representing a material in different phase states, and the texture library is used for representing the appearance and texture features of a geometric model and the material in real time when the geometric model and the material are subjected to local large deformation and caving damage under the action of a strong load; and the actual effect of the simulation working condition is dynamically displayed. The invention further provides a method for judging the phase change and completing real-time updating of the appearance texture of the material, in the calculation iteration process, the distribution of the material phase is judged by extracting the pressure and temperature values of the grid units in the calculation process and combining the phase change temperature and pressure values, and the texture map switching in the material phase change process is achieved according to the judgment result. Therefore, the states and the evolutionary process conditions of the model and the environment under the working conditions of high-speed collision, impact penetration, explosion and the like are truly and graphically shown.

Description

technical field [0001] The present application relates to the field of simulation, in particular to a method and system for displaying the shape state of a material. Background technique [0002] A wide variety of materials exist in nature, in shapes and colors and textures. All materials exist in three states: solid, liquid, and gas. The color and texture of the material will be significantly different in different phases (solid, liquid, gas). The numerical simulation method can simulate and observe the system in the whole process according to the conservation control equations of the system when studying the explosion and impact problems. The material model establishes the relationship between the stress, strain and internal energy of the material in the numerical simulation, and describes the physical response of the material under the external action. For example, the physical characteristics of hypervelocity impact are high temperature, high pressure and high strain ...
