Dynamic Responses of a Cylindrical Lattice Shell Structure with Explosion Venting Holes under Internal Explosion
Xuanneng Gao
This study investigates the dynamic response of cylindrical steel lattice shell structures subjected to internal explosions and evaluates the effectiveness of explosion venting holes in mitigating structural damage. A detailed numerical model was developed using ANSYS/LS-DYNA and validated against experimental results. The comparison shows good agreement in both overpressure and structural strain responses, confirming the reliability of the model. Internal explosions produce complex shock wave r
