ABSTRACT
Obesity is related to several clinical conditions and diseases including bone related diseases. Bones support the body’s soft tissues and can handle intense loads, yet they can damage or fracture under high loads. Computational mechanical behavior analysis of bones is crucial considering that it allows to understand the structural characteristics of the tissues and materials forming bone tissue and predict its mechanical limits. Finite element and meshless methods using radial point interpolators are well-known discretization techniques that can be used to analyze the mechanical response of structures and materials. This work, using the FEM and a meshless method, the proximal tibia is analyzed under two distinct load cases, corresponding to a healthy and an obese individual. An elastostatic analysis was performed, and stress and strain fields were obtained. The results show that higher strain and stress occur near the tibial tuberosity and that increasing the load magnitude increases the highest strain and stress values.
