The Discuss of the Finite Element Simulation Method of the Combined Connection with Bolts and Welds

In the paper, it takes the Finite Element Method (FEM) to analyze the capacity of the combined connection with bolts and welds. The rationality of the simulation directly affects the correctness of theoretical analysis. So, it needs comprehensive consideration about the reasonable choice of elements, attribute setup, reasonable division of the grid, boundary conditions and machining sequence, etc.
