Course aim
Course overview Finite Element Analysis (FEA) is a great tool for biologists, palaeontologists, doctors, veterinarians, and other life sciences specialities in which researchers face questions about biomechanics of living and extinct organisms. Elements like bone, arthropod exoskeleton, mollusc shells, or the stems and leaves of plants can be analysed using this technique. FEA is a non-invasive modelling technique, based on the principle of dividing a system into a finite number of discrete elements where the equations are applied. Although static and dynamic analysis can be solved using FEA, in this course only static analysis will be covered. In this course, there will be an introduction to the Finite Element in order to model biological structures and understand how they worked. It will cover all the steps involved in FEA (for static analysis) except the creation or reconstruction of the model, which will be covered in the previous course Introduction to 3D Imaging Technologies: Photogrammetry, Laser, CT-scan and (µ)CT-scan for Life Sciences. After the theoretical introduction, we will build and analyse 2D and 3D finite element models of skeletal elements and deepen on the methods and software’s required to perform FEA. Key questions as mesh size, boundary conditions, applied forces, scaling and numerical singularities will be thoroughly addressed.
