This study developed a smoothed particle hydrodynamics code based on micropolar continua for geomaterials, suitable for problems involving large deformation and shear strain localization. The performance of the newly proposed method was demonstrated through simulations of two typical geotechnical problems, and a parameter study was conducted on the scale effect in micropolar continua.
A smoothed particle hydrodynamics code based on micropolar continua for geomaterials is developed for problems involving large deformation and shear strain localization. Two typical geotechnical problems, i.e., biaxial compression test and sand column collapse, are simulated using classical and micropolar model to demonstrate the performance of the newly proposed method. A parameter study is given on the scale effect in the micropolar continua.
