This book introduces the basic structure, modeling methods, numerical
calculation processes, post-processing, and system functions of MatDEM,
which applies the basic principles and algorithm of the discrete element
method. The discrete element method can effectively simulate the
discontinuity, inhomogeneity, and large deformation damage of rock and
soil. It is widely used in both research and industry. Based on the
innovative matrix discrete element computing method, the author
developed the high-performance discrete element software MatDEM from
scratch, which can handle millions of elements in discrete element
numerical simulations. This book also presents several examples of
applications in geological and geotechnical engineering, including basic
geotechnical engineering problems, discrete element tests, three
dimensional landslides, and dynamic and multi-field coupling functions.
Teaching videos and the relevant software can be accessed on the MATDEM
website (http: //matdem.com).
The book serves as a useful reference for research and engineering
staff, undergraduates, and postgraduates who work in the fields of
geology, geotechnical, water conservancy, civil engineering, mining, and
physics.
