Abstract：Aiming at the problem of quantitative expression of load transferred law inside a given structure, a visualization method of load transferred law based on semi-analytical finite element method is proposed. The basic principle of calculating the load transferred amount in the local area is defined. Based on the semi-analytic finite element method, the mathematical expression of the load transferred calculation is derived. The continuous removal and recovery of local materials in the structure is simulated by using the element life and death technology. And the visualization process of load transferred law is given through secondary development. Taking rectangular cantilever plate, plate with hole, three-point bending plate and bending beam as examples, the load transferred law inside the structure are calculated respectively. The quantitative expression of the load transferred law not only gives the size of the load transferred in local region, but also gives the direction of the load.
