Abstract EN
Blast events and scenarios, as known, represent extreme phenomena that may result in catastrophic consequences, both for humans and structures.
Accordingly, for engineering applications, the reliable description of expected blast waves is a crucial step of the overall design process.
Compared to ideal theoretical formulations, however, real explosive events can be strongly sensitive to a multitude of parameters and first of all to the basic features (size, type, shape, etc.) of the charge.
In this regard, several advanced computer codes can be used in support of design and research developments.
Besides, the input parameters and solving assumptions of refined numerical methods are often available and calibrated in the literature for specific configurations only.
In this paper, with the support of the ANSYS Autodyn program, special care is dedicated to the numerical analysis of the blast wave propagation in the air due to several charges.
Five different explosives are taken into account in this study, including RDX, DAP-2, DAP-E, Polonit-V, and homemade ANFO.
The effects of different mixtures are thus emphasized in terms of the predicted blast wave, as a function of a given control point, direction, explosive mass, and composition.
As shown, relatively scattered peak pressure estimates are collected for a given explosive.
Comparative results are hence proposed towards selected experimental data of the literature, as well as based on simple analytical predictions.
The collected overpressure peak values are thus discussed for the selected explosive charges.
