The gravitational force of the object is not opposite and equal to the normal force, but one of the force of gravity's vector's components is. To find out how to calculate normal force with friction, use the friction calculator. For objects on a flat surface, the normal force is counter...
Since the contact potential is linearly distributed within each sub-triangle, the contact force can be obtained by segmentally integrating the contact potential along the boundary of the contact region according to Equation (3). Taking the edge DF of the target element as an example: Figure 3....
