Abstract
In addition to force-body interaction problems, deformable bodies problems are quite common in engineering applications and their investigations are more complex. The friction force and contact pressure formed between the surfaces are dominant and mostly studies are investigated considering the static and quasi-static conditions. However, considering the elastic/elasto-plastic deformation and dynamic conditions, the geometric surface shape is important. In this study, using the finite element analysis method, the pressure distribution of the surfaces containing square, trapezoidal and circular surface shapes on a flat surface and the dynamic deceleration condition during the surface interaction of an object with initial velocity are investigated. The material used is steel whose ground geometry does not show linear behaviour and nylon material is used for surface geometry. In order to ensure that the surface effect is dominant in the dynamic examination, a linear increasing pressure is applied on the examined part. In the results, it was determined that there is an irregularity in the stress and velocity deceleration curve. The effect of compression pressure and friction coefficient has been examined in detail and the results are discussed.
