In this study, a cylinder is horizontally immersed in granular media and moved toward different directions. The cylinder experiences a maximum force (F-m) when plunging downward and a minimum force when pulling upward. As the cylinder moves angularly, the force (F) gradually decreases with increasing angle between the cylinder movement direction and gravity (theta). F/F-m behaves similar to a Boltzmann function with theta; this function is independent of cylinder length and movement velocity and is slightly influenced by cylinder diameter and immersion depth. To illustrate the effect of movement angle (theta) on F/F-m, two estimation methods of resistance force are introduced to the angularly moving intruder. The computation results are consistent with experimental data in principle. (C) 2018 Elsevier B.V. All rights reserved.
