Webshear stress and shear rate (Figure 3). For non-Newtonian fluids shear stress (Ù) is de-fined by the Ostwald de Waele equation: Ù=ÎØ ÁØ n (3) where ÁØ is the shear rate (sec-1), n and k are indices of fluid internal properties, i.e. adhesion, cohesion.1 For Newtonian fluids flowing upon a planar sur-face, shear stress is determined ... Webtransverse shear stresses σθz through the thickness of this symmetric cross-ply panel is shown in Fig. 5. The distribution of interlaminar shear stress is anti symmetric to middle plan of panel (z 0). From Fig. 5 it is noted that exactly at the free edge = 0 the shear stress σθz satisfy the traction free boundary condition expect near
