Figure 8 Modified Blast Wave Profile Using Triangular Shape For Both To characterise the positive phase of blast wave, the kinney and grahm’s equations are most suitable and the negative phase can be characterised by a triangular form with peak negative. This paper is providing various blast computation equations, charts, and references in a concise form at a single place and to serve as base for researchers and designers to understand, compare, and then compute the blast wave parameters.
Figure 8 Modified Blast Wave Profile Using Triangular Shape For Both Different empirical techniques available in the form of charts and equations are reviewed first and then the various blast wave parameters are computed using these equations. The standard approach in protective design is to model blast loads with a triangular pulse shape which is characterized by the peak reflected overpressure and the reflected impulse. Having presented aspects of direct blast wave loading on target structures of various shapes, we next move on to indirect loading cases, where the properties of the blast wave are modified by another structure before it impacts the structure of interest. In this work, we examine the relationship between shock tube adjustable parameters (saps) and swps that can be used to control the blast profile; the results can be easily applied to many of the laboratory shock tubes.

The effective blast parameters such as standoff distance, angle of incidence, explosive type and charge weight with its damaging effects discussed by various researchers have been overviewed in the present work. Cterizing that interface phenomenon. this work aims to give an insight on the blast wave–structure interaction event. a methodological approach combining the friedlander equation and the theory reporte. The analysis and design of structures subjected to blast loads require a detailed understanding of blast phenomena and the dynamic response of various structural elements. the study is made to understand the properties of blast wave by estimating the blast wave parameters for various charge amounts placed at various distances. In this case, the idealized blast load for the wall of a structure facing the charge is the triangular pressure pulse where the peak positive reflected pressure pr and the reflected positive specific impulse ir are used to determine the ‘fictitious’ pulse duration.
