DIFFRACTION OF HARMONIC AND NON-STATIONARY WAVES

One of the most pressing global challenges today is ensuring the seismic resistance of underground structures constructed in seismically active regions through the application of modern engineering techniques and technologies. Worldwide the study and practical implementation of stress-strain analysis and wave diffraction phenomena in underground structures exposed to explosion-induced and seismic waves are becoming increasingly important. In this context preventing resonance phenomena arising in various structural elements of modern underground facilities under dynamic loads through the use of advanced technical means and contemporary software tools holds great practical significance.
