Analytical Solution for 3D Transient Response of Cylindrical Cavities Under Impact Loading

This study presents a novel three-dimensional analytical model for the transient dynamic response of cylindrical cavities in elastic media under triangular impulse loading. The model uses wave function expansion and Laplace transforms to derive frequency-domain solutions, which are then converted to time-domain results and validated against experimental data. This work advances understanding beyond traditional two-dimensional or steady-state assumptions, with implications for tunnel and pipeline safety.
