Digital Image Processing Method Based Partial Differential Equation for Rock’s Microstructure
Jun Yue, Pan Ling Huang, Jin Feng Cao, Bao Feng · Applied Mechanics and Materials · 2011
A digital image processing method based on partial differential equation(PDE) for rock’s heterogeneity is introduced. The actual microstructures of the rock sample was obtained by multiphase level set method. The main components of granite, quartz, feldspar and biotite, can be easily identified. The numerical results show that the method has advantage of self-adaptation and is benefit for grid generation in the following mechanical properties analyzing with Abaqus.
