Design optimization with ESTECO modeFRONTIER – Shaped charge device case study

This study explores an optimization methodology for designing shaped charge devices that meet the dimensional and performance requirements associated with normal impact conditions of the generated jet on a concrete target.
A range of input variables are investigated, including device dimensions such as diameter and length, as well as the liner's thickness at the symmetry axis and at the extremity, the case thickness, and the liner half-angle.

The optimization process is executed through the modeFRONTIER software, which employs the MOGA-II genetic algorithm to maximize two distinct objective functions under constraints aligned with predefined requirements. Specifically, these objective functions are the Depth of Penetration (DOP) and the borehole volume realized by the generated jet into the target.
Designs on the Pareto frontier emerge as primary candidates for further evaluation.
This work highlights the importance of optimization processes in creating effective shaped charge devices that can satisfy rigorous performance demands in real-world scenarios.
