Finite Element Modeling of Blast Vibrations and Study of Vibration Control Criteria

Various types of waves originate from a blast source to propagate through rock/soil media away from the blast. Input vibration to a structure depends on the soil-structure interaction which varies with the dynamic properties at the intersection as well as the stress and strain levels developed from the vibration of the structure-ground system. Hence it is important to study such effects on the response of a structure due to blast loads and this knowledge can be used in the design and control of blasts that are carried out close to buildings, highways and other structures.
