Pressure-impulse diagrams using coupled single degree of freedom systems subjected to blast load
https://orcid.org/http://orcid.org/0000-0002-3209-7033
Pressure-Impulse (P-I) diagrams, a widely popularized approach, relate different damage levels and are utilized in the preliminary design of structural elements subjected to blast loading. In the presented paper, P-I diagrams generated using coupled Single Degree of Freedom (SDOF) model subjected to blast loading are studied. It may be noted that these P-I diagrams for the blast in the dynamic and impulsive regime are very different from those derived by applying the uncoupled SDOF approach. The resultant P-I diagrams are further compared with those based on Timoshenko beam theory, including the higher modes effect. The findings are intended to shed light on how to develop simpler, more accurate methods for calculating the combined reaction of structural parts exposed to various blast loading ranges. The effect of shear and flexure resistance ratio on P-I diagrams has been studied parametrically. P-I diagrams show only small fluctuations as they approach quasi-static regimes, indicating that they are not sensitive to the shear and flexure resistance ratio for a distant range of blast loadings.
