In addition, the HPEM Effects Program investigates the fundamental mechanisms resulting in these disruptions or failures, in order to predict and model the effects.Numerical SimulationsThe mission of the High Power Electromagnetics (HPEM) Numerical Simulations Program is to develop, improve, and utilize the world-class simulation tools within RDH, which enable the effective development of modern HPEM systems.

The work to be performed includes the enhancement of existing HPEM system performance modeling tools, primarily ICEPIC, as well as the development of new HPEM performance modeling and simulation tools for future modeling needs. The work also includes the application of these tools in the analysis of HPEM system performance.

Further, application processes shall take into account the requirements of the coated / plated components in the small arms system - the application processes shall not adversely affect the substrate material in ways that may affect performance, including dimensional changes or effects on material properties, such as strength or fatigue life.

Determine the strength, deformability, and failure modes of two representative slab-column connections along grid line 9.1, including effects of slab drops, a specific beam type, column offset bent reinforcement, and prior failure of the plaza slab south of and adjacent to grid line 9.1, with uncorroded reinforcement, and obtain data that can be used to support numerical simulations of the behavior of the building. 

WE SEEK TO ANSWER THESE QUESTIONS BY CONDUCTING SYSTEMATIC NUMERICAL SIMULATIONS WITH VARYING INTERNAL AND EXTERNAL INPUTS. OUR MHD MODEL INCLUDES THE 10-DEGREE DIPOLE TILT OF JUPITER S MAGNETIC FIELD AND THE PLASMA LOADING ASSOCIATED WITH IO AND ITS TORUS IN A REALISTIC MANNER. THIS MODEL WILL ENABLE US TO INVESTIGATE HOW INTERNAL AND EXTERNAL PROCESSES, SEPARATELY AND IN COMBINATION, AFFECT THE MAGNETOSPHERIC STRUCTURE AND ITS DYNAMICS.

Determine the strength, deformability, and failure modes of two representative slab-column connections along grid line 9.1, including effects of slab drops, Beams Type A, column offset bent reinforcement, and prior failure of the plaza slab south of and adjacent to grid line 9.1, with uncorroded reinforcement, and obtain data that can be used to support numerical simulations of the behavior of the building. 

Studies may utilize historical nuclear and/or chemical explosion data, numerical simulations, and/or new laboratory or field experiments.Velocity, Attenuation, and Full Waveform Earth ModelsThere is strong and particular interest in improved prediction of full seismic waveforms, phase amplitudes, and travel times at local and regional distances.
