EFFECT OF POROSITY IN SUBSTITUTE BIRD UNDER HIGH VELOCITY LOADING
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 0, Vol 4, Issue 10
Abstract
Impact events involving laminate composites had been largely studied through computational approaches, due to mainly to the technical difficulties and high costs associated with experimental tests, and the availability of highly sophisticated computational codes. The impact constraints are active only on the contact / target interface, so energy conservation is enforced only for contact elements. The underlying finite elements defining the interior of impacting bodies do not satisfy energy conservation. In the present work, high velocity impact event of ‘dummy bird’ against balanced Epoxy_Carbon_UD laminate composite structure was simulated through AUTODYNE explicit finite element package. Smoothed particle hydrodynamics (SPH) techniques is adopted to describe the motion of the impacted composite plate and the soft body projectile, with different porosities. The obtained energy and momentum variations with time from different porosities of two bird models are compared and results were plotted.
