Controlled Vibrations with Boundary Conditions for Periodically Thin Structure

Journal Title: Romanian Journal of Acoustics and Vibration - Year 2013, Vol 10, Issue 2

Abstract

This paper studies the homogenization of controlled waves problem over a threedimensional cross linked structure reinforced that depends on two small parameters ɛ - the period and δ - the small thickness of the material. Neumann condition heterogeneity lead by passing to the limit as ɛ and δ, to a limit problem of controlled waves with a foreign term.
