DYNAblast—A software to obtain the behavior of plates subjected to blast loads

Abstract

Structures subjected to blast loads have been studied in the past decades to characterize their behavior. However, this type of analysis can be difficult, which normally occurs in structures subjected to high-impact dynamic loads. Based on this, software was developed to represent the behavior of thin plates subjected to explosive loads, in terms of displacement, strain, stress, and frequency content. Moreover, parametric analysis is also possible, considering variations in the mass of the explosive and its distance from the plate.
