Lattice defect of a dislocation-type -- analogy of a quantum of
torsion in discrete geometry:

Lattice defect of a disclination-type -- analogy of a quantum of
curvature in discrete geometry:

Atomic visualization of the disclination defect and its influence
on bending of the crystal lines around:

(configurations generated with software "Molecular
Dynamics" written by P. Marecki)

Time-dependent distorsion waves deforming local distances between
the lattice nodes -- analogy of metric (gravitational) waves:
