Abstract :
The knee is a multi-purpose part of the body and plays various roles in the body s movement and posture. This member is actually a joint that also plays the role of support for the body; A firm and yet sensitive support. In the position of support, the knee performs its duties well in all stationary and moving positions such as standing, bending and straightening, walking and running, and in the position of the joint, whenever necessary, with the possibility of inward and outward rotation in slight movements, it enables many activities. In this article, the three-dimensional model of the knee bone is first modeled by the powerful CATIA software, and then it is entered into the ABAQUS software and the necessary analyzes will be performed on it. For this purpose, we first make a three-dimensional model of the knee and the ossification of the desired leg with the help of CATIA software, and then we analyze the said model with the help of ABAQUS analysis and simulation software, which processes based on the finite element process. In this article, the analysis and stress analysis of the knee under the effect of hard impact on it is the focus and final goal. In order to analyze and investigate the behavior of the knee, all the dynamic loads applied to the knee bone and its actual boundary conditions will be defined and then a regular network of elements will be created for the purpose of meshing and analyzing the knee.
