dc.description.abstract-translatedAccurate prediction of air-blast effects requires reliable JWL EOS parameters, but traditional cylinder tests are costly and complex. This study presents a methodology to determine JWL parameters using height-of-burst experiments combined with numerical optimization. PG3 explosive detonations (0.7–1.4 kg) were simulated in a 2D axisymmetric LS-DYNA model, with experimental pressure–time histories guiding the optimization. The calibrated parameters reproduced overpressure profiles with errors below 10% and were validated using Viperen
