Simulation bone drilling process by using explicit method in Abaqus

In this tutorial Simulation bone drilling process by using explicit method in Abaqus has been investigated.The drilling of bone is ubiquitous in many fields of surgery including orthopaedics, neurosurgery, plastics and reconstructive, craniomaxillofacial and ear nose and throat.A cylindrical tunnel is typically prepared in bone using a surgical drill-bit to accommodate a screw or other threaded device for rigid fixation which is provided by the integration of bone (cancellous and/or cortical) with the screw threads. In this configuration bone screws are resistant to axial and shear forces as well as bending moments and therefore suited to the load-bearing function of the skeleton during locomotion. Drill-bits are also used in the preparation of bony tunnels, such as in anterior cruciate ligament reconstruction.You can see a figure of assembled part at below

Dynamic explicit procedure is appropriate for this type of analysis. General contact with considering internal damage and erosion is used as input file.The rotation velocity with axial displacement is applied to the drill and during the simulation the drill penetrate into the bone and create hole inside it. You can see some figures of this simulation at below
