Biography

Current assignments include performing advanced 2-D axisymmetric and 3-D structural evaluations and providing engineering support to development programs for large caliber concept munitions, die casting technologies, and non-lethal acoustic technologies. Evaluations include projectiles and accompanying cartridge components under static, quasi-static, in-bore acceleration, muzzle exit deceleration and discard loading conditions as well as performing structural design optimizations and parametric sensitivity to reduce parasitic and total cartridge mass. Current assignments also include performing advanced 2-D axisymmetric and 3-D thermal analyses involving intricate mass, convective, and radiative transfer regimes for the safety verification of commercial spent nuclear fuel transport, transfer, and storage systems governed by the NRC. Solution methods included large-scale Finite Element Analyses (FEA), large-scale Finite Difference Analyses (FD), a combination of the two, or a combination of empirical and traditional hand calculation methods.
