This study investigates the ultimate bearing capacity of a rigid strip footing on a sandy slope using the Rigid Plastic Finite Element Method (RPFEM). To accurately represent a wide range of frictional conditions at the footing roughness, a new interface element was introduced, capable of accommodating both perfectly rough and perfectly smooth conditions.

The study extensively investigated the ultimate bearing capacity (UBC) of an eccentrically loaded foundation under two scenarios (horizontal sandy soil and sandy soil slope), utilizing the Rigid Plastic Finite Element Method (RPFEM). To precisely simulate a diverse range of frictional conditions on the foundation surface roughness, a novel joint element is introduced, capable of accommodating both perfectly rough and perfectly smooth foundations.

The article numerically simulates the vibration reduction of a spur gear transmission by using damping particles placed in technological holes designed on the gear itself. The vibration of the gear transmission is reduced based on friction and inelastic collision which eliminates the vibrational energy by the loss during the motion of the damping particles within the technological holes.

This paper presents the results of determining the coefficient of friction when cold plastic deformation by the method of cold ring upsetting with different lubricants. The ring upsetting process is performed with varying degrees of deformation with three lubricants used: industrial oil, cooking oil, and zinc sulfate powder. Based on the deformation and dimension change of the samples after the upsetting, the coefficient of friction was determined by correlation comparison with the friction calibration curve performed by Male and Cockcroft.

In this paper, we report in detail the compressive strength of wet granules under a diametrical compression test by means of the discrete element simulations. The numerical method is coupled with the capillary cohesion law which is enhanced by the cohesive forces between grains having a gap not exceeding a rupture distance.
