“…Reflection of shock waves from structural surfaces requires the use of complex FSI algorithms. Therefore, simulations involving the interaction of blast waves with structures are more challenging than simulating the free expansion of blast waves in air [20]. Figure 6 illustrates the variation of the reflected overpressure over time for the C1-C10 Cartesian simulations.…”

Landmine threats play a crucial role in the design of armored personnel carriers. Therefore, a reliable blast simulation methodology is valuable to the vehicle design development process. The first part of this study presents a parametric approach for the quantification of the important factors such as the incident overpressure, the reflected overpressure, the incident impulse, and the reflected impulse for the blast simulations that employ the Arbitrary LagrangianEulerian formulation. The effects of mesh resolution, mesh topology, and fluid-structure interaction (FSI) parameters are discussed. The simulation results are compared with the calculations of the more established CONventional WEaPons (CONWEP) approach based on the available experimental data. The initial findings show that the spherical topology provides advantages over the Cartesian mesh domains. Furthermore, the FSI parameters play an important role when coarse Lagrangian finite elements are coupled with fine Eulerian elements at the interface. The optimum mesh topology and the mesh resolution of the parametric study are then used in the landmine blast simulation. The second part of the study presents the experimental blast response of an armored vehicle subjected to a landmine explosion under the front left wheel in accordance with the NATO AEP-55 Standard. The results of the simulations show good agreement with the experimental measurements.

A sensitivity analysis of blast loading parameters is performed to determine which of the parameters'uncertainty has the greatest e¤ect on the maximum de ‡ection of an aluminum plate subjected to a blast load. A numerical simulation using the Monte Carlo method is used to obtain the ensemble averages of the probabilistic runs. The random variables were given a uniform distribution. Two simpli…ed loading models are used. The …rst has an instantaneous rise with an exponential decay, represented by the modi…ed Friedlander equation. The second loading model has a linear rise with an exponential decay. Both of these models are simulated with three di¤erent blast scaled values, giving a total of six di¤erent cases. In addition, the de ‡ection trends due to the loading parameters as uncertainty increases is quanti…ed. Probability density functions of the maximum de ‡ection are also presented. The probabilistic results and trends are also explained using deterministic methods. It appears that the duration time of the loading models is generally the most sensitive parameter to uncertainty.ii Acknowledgements First and foremost, I would like to acknowledge my advisor Professor Haym Benaroya. I feel very lucky and honored to have him as my advisor. He is a great advisor and is always willing to give up his time to help. In addition, he is constantly looking out for his students.For instance, he would make sure that other professors, whom I was a teaching assistant for, do not give me a workload greater than the amount I was supposed to have. He has also provided me with a great deal of support, both academically as well as …nancially.A very big acknowledgement goes to Dr. Jason Florek who has become a great colleague and friend of mine. From the start he has helped me to understand the subject of blast loads and supplied me with many journal articles and books on the subject. He was always willing to help answer any questions I had on the subject, or for that matter, on any subject.I also used his response model in my work. On a personal note, he is always fun to hangout with and made it enjoyable to come to the o¢ ce or go to conferences. He even learned how to play goalie for our MAE United soccer team. Jason, thank you very much for everything.

Explosives and propellants are chemical compounds that undergo chemical decomposition reactions at very fast speeds, producing gaseous products, and a great deal of heat. In some circumstances a blast wave can be produced. The information provided here gives an introduction to this process covering the theory of detonation and deflagration. Explosives can be divided into three classes, ( 1 ) primary explosives, ( 2 ) secondary explosives, and ( 3 ) propellants. The behavior and performance of these three classes of explosives is discussed. Physical and chemical data on primary and secondary explosives is given together with details of new high temperature explosives. Lastly future developments in explosives technology are presented with regards to enhancing the performance, insensitive munitions and demilitarization.
