Materials and processes that fail to satisfy the continuity hypothesis are discussed and analyzed. A method based on analytical and computational considerations for the dynamics of interacting particles is developed as an effective alternative or complementary approach for the traditional continuum mechanics for such problems.

Applications of the particles dynamics for thermomechanical problems at different scale levels are considered, starting form nanolevel (description of nanomechanical systems using molecular dynamics), mesolevel (deformation and fracture of solids with microstructure), macrolevel (astrophysical processes modelling). The basic concepts allowing establish the link between microscopic parameters of the mathematical model and macroscopic parameters of the object under consideration are outlined.
The presented methodology is used to solve practical problems including high frequency percussive drilling of hard rock formations.
