Context of the project
Knee ligaments (figure 1) are elastic bands of soft tissue with a complex microstructure and biomechanics, which are critical to determine the kinematics as well as the stress bearing behavior of the knee joint. Their correct implementation in terms of material models and properties is therefore necessary in the development of finite element models of the knee, which has been performed for decades for the investigation of both its basic biomechanics and the development of replacement implants and repair strategies for degenerative and traumatic pathologies. Indeed, a wide range of element types and material models has been used to represent knee ligaments, ranging from elastic unidimensional elements to complex hyperelastic three-dimensional structures with anatomically realistic shapes [1].
The aim of the thesis is to analyse the effect of different ligament modeling in terms of material properties and in terms of modeling representation, changing from 1D (springs, trusses, and beams), 2D (shell and membrane), and 3D elements (solid).
