A R T I C L E I N F O A B S T R A C T Article history: Received: 14 December, 2020 Accepted: 19 January, 2021 Online: 05 February, 2021 A comparative analysis of formulas for blast wave overpressure is presented in the paper, and models were compared with available experimental data. The Kinney and Shin models show the best agreement with experimental data (Kingery-Bulmash) for free airburst, while for surface burst, Swisdak, Vanuci, and Jeon models predict test data most accurately. One of the novelties in the paper is introduction of new exponential and power functions for blast overpressure estimation, giving good agreement with experimental data. Also, several numerical simulations of free airburst explosions were performed to introduce methodology, and compare the data obtained with experimental data. A detailed description of the procedure for these simulations was provided – a contribution to numerical modeling of blast wave phenomena.
