This book is a practical investigation of Discrete Element Method and Bounded Particle Method in LS-DYNA using real world sandstone tests data as calibrators and references. The methods, with a critical approach and merit based comparison, were mainly evaluated within the frame of the code formulas. However, some subroutines using the code standard language and MATLAB scripting were also applied to hopefully extend the capabilities. The content of this book shall be exploited further in other publications regarding the application based rock-tool design scenarios and rock mechanics numerical modelling diagnosis.
