Dynamic Sensitivity of a Multi-block Assembly Subjected to Horizontal Harmonic Excitation

Dynamic sensitivity of a one-dimensional assembly of eight rigid blocks undergoing external harmonic vibrations is investigated. Several parameters are considered as dynamic attributes: time variation of the mass inertia of the assembly and for each block the average over all the simulation of granular temperature, relative velocity, coordination number. Numerical simulation is based on the Non Smooth Contact Dynamics (NSCD) time integration framework Solfec (http://code.google.com/p/solfec/). Sensitivity space parameters include a range of excitation frequencies and velocity amplitudes.
