Complex dynamics in non-Newtonian fluid-structure interaction

Abstract. This paper presents the results of an extensive experimental campaign focused on analysis dynamic interactions between elastic structure and a non-Newtonian fluid. The is circular cylindrical shell clamped in one end to shaking table other heavy rigid disk. has been investigated both presence absence fluid mixture water corn starch flour, commonly called Oobleck. experiments were carried out at low high vibrating energy, order clarify influence different conditions: changing modal properties, onset complex dynamics when fluid-solid transitions take place
