MAIN RESULTS
Interaction solitons, shallow water
Surface elevation in the vicinity of the interaction area, corresponding to incoming solitons with equal amplitudes but different angles between their crests.
MAIN RESULTS
Emergence of solitons
Emergence of solitons from an harmonic excitation in force field. After a certain transfer period the emerging coherent pattern is seen with amplified solitons.
MAIN RESULTS
Wave motion and dynamics
Mindlin model for microstructured solids, 1D. Two trains of solitons emerging from a single input.
MAIN RESULTS
Phase transition
Stress wave changes the shape of a martensitic inclusion in an austenitic solid.

Martensite
Austenite
Shift of a phase boundary (green line) between martensite and austenite under localized pulse-type stress load at the left boundary. The influence of shear causes a rugged interface.
MAIN RESULTS
Biophysics
Schematic representation of the biochemical processes in the reaction-diffusion model of the heart cell.
MAIN RESULTS
Biophysics
Lyapunov exponent map on the para-meter plane for the periodical driven nerve pulse equation modelling cardiac conduction.
MAIN RESULTS
Soft matter physics
A chaotic mixing of an initially smooth field of dye by a smooth chaotic velocity field leads to complex multifractal patterns.
MAIN RESULTS
Stress analysis
The idea of acoustodiagnostics.
Interaction of two counter-propagating acoustic waves.
MAIN RESULTS
Stress analysis
Polariscope AP-04SM for determining residual stresses in a glass specimen.
MAIN RESULTS
Tomography
Geometry of the high-pressure lamp and axial stress field in the axisymmetric part.
MAIN RESULTS
Wave motion and dynamics
Testing device for piano hammers. The hysteretic parameters of felt are determined from the measured nonlinear force - compression curves.
