Biomechanical Modeling And Finite Element Simulation Of Human Muscle Tissue

With the development of computer simulation technology,virtual reality technology emerges as times require.Virtual operation system is a typical application of digital medicine in virtual reality technology.Its significance lies in the operation planning and operation training and so on so that we can decrease the risk of operation failure.As the key point and the difficult point in the virtual operation system,biomechanical modeling and its solution module of human tissue is closely connected with the simulation precision in the whole operation system.This paper mainly aimed at the research of the biomechanical modeling and its solution method of human muscle tissue.At first,we studied the anatomical structure of the human muscle tissue and its biomechanical properties.We take human muscle tissue as the approximate incompressible nonlinear hyperelastic material and build a biomechanical model of human muscle tissue.Second,according to the finite element theory and the theory of continuum mechanics,we calculate the biomechanical modeling of human muscle tissue.In the process of solution and considering both the energy and material,we combine the main invariant deformation with Green strain to solve problem of nonlinear material.To solve the geometric nonlinear problem,we divided the strain tensor into two parts of linear and nonlinear and take advantage of T.L..The process of this solution is implemented in the Visual studio environment.At last,through the comparison and analysis of the data from the simulation of compress and tensile and the experiment data from the existing literature,we verified the validity of biomechanical modeling and solution program of human muscle tissue.The innovation of this paper is to complie a isolated finite element analysis programme of human muscle tissue in the VC environment.In the certain condition of applied load and fixed constraint,we complied the finite element analysisprogram of human muscle tissue so that we can calculate the deformation caused by the mesh model of human muscle tissue.Through comparing the analysis result with experiment,we deem that the program can basically satisfy the command of the biomechanical modeling and solution module of human muscle tissue in the virtual operation system.At the same time,we also give some reference about research of modeling and solution method of other human tissue.
