description The invention discloses a finite element modeling method for a variable-strength material, and the method comprises the steps: carrying out the finite element modeling: carrying out the overall finiteelement modeling of a part made of the variable-strength material, and enabling a grid to use a deformable shell unit; and determining the change direction of the material strength in the three-dimensional coordinates; in the three-dimensional coordinate, calculating the yield strength according to the change direction of the material strength, and enabling the yield strength to continuously change according to the spatial position in the three-dimensional coordinate. According to the finite element modeling method for the variable-strength material, the modeling process of the variable-strength part can be effectively simplified, and the modeling time can be saved by 80%. In addition, compared with a step curve of a traditional splitting method, a continuous curve is used in the yield strength of the transition
