To evaluate the loads due to dry bulk cargoes on the inner hull of bulk carriers, effects of the particle-wall frictional properties on internal lateral pressure during sway motion using Discrete Element Method (DEM). The dynamic load distribution shape in the lateral excitation analysis differ from that of liquid cargo. The results of the analysis using realistically set coefficients, the internal friction of the cargo and the friction between the cargo particles and the wall surface, demonstrated that the dynamic pressure decrease at the side wall where the particles collide because of shearing force on the walls. However, there was no significant difference in their decreasing effect in the range of realistic friction coefficients.
