The components of shear stress in the oscillatory sheet-flow layer, especially concerning the inter-granular stress, are considerably unknown field because of difficulty in experimental measurements. In the present study, components of the shear stress in the oscillatory sheet-flow layer have been addressed by the LES for the particulate flow based on the Euler-Lagrange coupling. The inter-granular stress has been calculated from the solid-liquid interaction term. Then the vertical profile of each component of the shear stress has been shown in some phases. Furthermore, the predominant region for collision and contact has been found by considering both the particle concentration related to the interstitial area between particles and the turbulence intensity for particle velocity.
