Abstract
The invention relates to a biomechanics modeling method for subcutaneous adipose tissues based on linear elasticity and superelasticity models. According to the biomechanics modeling method, the problems that an existing subcutaneous adipose tissue model is low in simulation accuracy and speed are solved. The biomechanics modeling method comprises the following steps: (1) establishing a geometric model, and dividing grids; (2) establishing a linear elasticity biomechanics model; (3) establishing a superelasticity biomechanics model; (4) carrying out finite element simulation on the superelasticity biomechanics model according to the step (1) and the step (2); (5) carrying out finite element calculation on the linear elasticity model; and (6) carrying out finite element simulation on a mixed linear elasticity and superelasticity model. By virtue of comparison on a simulation result and an experimental result, the accuracy of the biomechanics modeling method is verified. By virtue of comparison on simulation time of the single linear model and superelasticity model, high efficiency of a simulation algorithm of the mixed linear elasticity and superelasticity model is verified. The biomechanics modeling method is applied to the field of biomedical engineering.
