Abaqus assembly of screws on a fractured bone

Description

What is Abaqus?

Abaqus is an FEA software for multiple engineering purposes. Many researchers, companies, and students use Abaqus to simulate simple and complex models. Abaqus is a flexible tool to analyze processes compared to other software. Even though it has a user-friendly environment, it is not easy to learn as the license is extremely expensive. Therefore, tutorial videos on this software are not easy to find or are too expensive. Before explaining the Abaqus tutorial details, we should first learn what Abaqus covers and what exactly it is. We use the following explanation from Abaqus 6.14 documentation to give a better explanation of Abaqus software.

Abaqus/CAE  is a Complete Abaqus Environment that provides a simple, consistent interface for creating, submitting, monitoring, and evaluating results from Abaqus simulations. we can divide the Abaqus/CAE modules, where each module defines a logical aspect of the modelling process; for example, defining the geometry, defining material properties, generating a mesh, submitting analysis jobs, and interpreting results.

To learn more please watch the following short video which explains different parts of the software in less than 35 minutes:

Abaqus assembly

In Abacus software, when your finite element model consists of several parts or you need to create several components, you need to use the Abaqus assembly module to put these parts together. The tools of this module are very similar to the tools of CAD software assembly environments such as CATIA and SolidWorks. In fact, after applying the defined loads or initial conditions, the parts move and change according to the position that you have precisely specified in the assembly module. Using assembly module tools does not require academic knowledge and study and is merely a technical and experimental matter. In this video, some commonly used assembly module commands are explained in the form of a biomechanical example.

Tutorial video

In this tutorial, we use tibia bone and create the cortical and spongy parts. To do that we use the merge/cut option in Abaqus. This option enables us to place one component inside the other one which is very common in biomechanical simulation. Next, we create a gap on the bone to simulate the fracture. Then we assemble the plate and screw on the fractured bone. To place the screws we again use the merge/cut option. Finally, we assemble the tibia fractured bone model with implants and orthopedic screws. All of the parts are modelled using CAD software and imported to Abaqus. Then, it is ready for analysis in Abaqus software.
