| Abstract: | According to weld strength calculation theory, FEA numerical analysis and bending test of combined steel components, the mechanical performance of fillet weld in hull structure is studied. The contrasting results of theory analysis, numerical calculation and model test indicates the correctness of theoretical calculation method of fillet weld shear stress, the consistency of the test measured value and the theory calculation value, the relia- bility of this determination method, and the reference value in future study of welding factors verification. |
