Biomechanics is a branch of Biophysics that applies mechanical principles and methods to quantitatively study mechanical problems in organisms.
The study of rheological properties and dynamics of biomaterials is not only helpful to understand the physiological process of human body, but also can provide scientific basis for the design and manufacture of artificial organs.
At present, it is widely used to carry out mechanical simulation for different parts of the human body with the existing numerical software of computational structural mechanics and computational fluid mechanics. With the powerful and perfect modeling function and interface tool of the existing finite element software, we can build three-dimensional human skeleton, muscle, blood vessel and other organs and tissues, and simulate their biomechanical properties. Various types of boundary conditions and load constraints (geometric constraints, fixed loads, impact loads, temperature characteristics, etc.) can be simulated to simulate various types of structural statics, dynamics, fatigue, hydrodynamics and so on, so as to obtain the deformation, stress / strain distribution at any part under different virtual experimental conditions. The characteristics of internal energy change, flow characteristics and limit failure prediction are also discussed.
