Course Objective

The simulation of stent behavior reveals detailed stress-strain distributions that are important in predicting device fatigue life. The complex geometry and material behavior of stents result in highly nonlinear and challenging analyses. This course focuses on the use of Abaqus for modeling and analyzing stents. However, its content can also be useful when modeling other types of medical devices. The course is targeted at engineers responsible for the design of medical devices who are looking to accelerate their understanding of the highly complex mechanical behavior associated with performance of such devices.

The topics include:

• Creating geometry for modeling stents and tools
• Choosing the proper element type
• Material models: elastic-plastic (Stainless Steel), superelastic-plastic (Nitinol), hyperelastic (vessels)
• Performing stent analyses: Static, Implicit and Explicit Dynamics
• Contact and constraints
• Postprocessig stent analyses
• Fatigue evaluation using Goodman Diagrams

Who Should Attend

This course is recommended for engineers with experience using Abaqus. Some understanding of Abaqus/CAE is helpful but is not required.
