NON-LINEAR ANALYSIS FOR ULTIMATE LOADING CAPACITY OF CAST TUBULAR T-JOINTS

摘要

In this paper, we performed a lot of parametric analysis of cast T-joints. The geometry model was established using Solidworks. Non-linear analysis was carried out using the commercial finite element programme Ansys. Parametric equations of ultimate loading capacity derived from the results of finite element analysis are presented for the usual range of basic shapes of T-joints under axial loading, in-plane and out-of-plane bending. The sensitivity of the ultimate loading capacity in cast tubular joints to variation in the geometric parameters has been assessed. Besides the parameters which governing the stresses in welded joints, an additional parameter ρ that is defined by C.D.Edwards has been introduced to describe the size of fillet. In this paper, the sensitivity of ultimate loading capacity of cast tubular joints to the parameter ρ is presented.
