The trachea, commonly known as the windpipe, is a cartilage tube that connects the larynx, which is an organ in the neck, to the bronchi tubes in the lungs. It is formed by several rings called tracheal cartilages. Each ring is connected to muscle and connectivity tissue on the back side. The trachea branches into two primary bronchi tubes before connecting to the lungs. With each inhalation, the trachea widens and elongates. Similarly, as we exhale, it returns to its resting position. During the respiration process, the air moving in and out of our lungs exerts forces on the inner walls of the trachea. In this course, we will learn to simulate the effect of this pressure load on the trachea. The course demonstrates how realistically human body parts can be simulated using Ansys software. Such engineering simulations help medical professionals and bioengineers evaluate and design materials capable of replacing human body parts by recreating the exact physical conditions.

This SimCafe Structural Course was developed by Dr. Rajesh Bhaskaran, Swanson Director of Engineering Simulation at Cornell University, and Zach Michael Brothers. It serves as an e-learning resource to integrate industry-standard simulation tools into courses and provides a resource for supplementary learning outside the classroom. In this course, we will learn to simulate the effect of air pressure on the trachea using Ansys Mechanical. We will highlight the step-by-step procedure to perform the structural analysis.

The structures are subjected to various loading. The objective of the design engineer is to ensure that the structure has minimum stresses and strains. Using the Ansys optimization tools, engineers can solve structural optimization problems. The optimised designs is where multiple input parameters can control and optimize the design objectives. In this SimCafe Course, we provide a detailed walkthrough of the Optimization analysis of a structural problem in Ansys Workbench.

Beams are one of the most used fundamental structural elements. The deflection and load-carrying characteristics can be obtained using the beam theory formulation. In this course, we simulate the load-carrying capacity of a simple cantilever beam using beam elements. We will also estimate the modal frequencies using beam theory. On comparing the obtained results, we find that the Ansys beam element results match closely with the beam theory. In this SimCafe Course, we will learn a detailed setup of the modal analysis of a Cantilever structure using beam elements in Ansys WorkBench.

Generally, the solution in Ansys Mechanical is calculated in a cartesian coordinate system. In case of a curved structure, such as curved beams and pressure vessels, it is more intuitive to visualize the results in the axial, radial, and circumferential directions. In this course, we will use a solved model of a curved beam with a rectangular cross-section under a moment and learn to post-process the results in the cylindrical coordinate system. In this SimCafe course, we will outline the detailed steps to post-process as well as discuss how to interpret the results using Ansys Mechanical.
