Modeling of indentation and slip of wedge punch
To determine the load-carrying capacity of the drillpipe slip, it is necessary to calculate the drag force on the surface between the pipe and the slip. To improve such capacity, the grip surface is provided with teeth that can indent into the pipe body.
