A grain texture model to investigate effects of grain shape and orientation on macro-mechanical behavior of crystalline rock

Grain texture characteristics play vital roles in modulating the anisotropy, strength, and ductility of crystalline rock. Grain textures (shape, size, orientation and heterogeneity) are a key parameter controlling response but are challenging to incorporate in a quantitative manner. We propose and incorporate a grain texture model (GTM) into granular mechanics modeling by the distinct element method (DEM). This model seeds then grows individual...
