APPLICATION OF FINITE ELEMENT METHOD TO THE ANALYSIS OF AXISYMMETRIC THERMAL ELASTO-PLASTIC STRESSES IN WELDING

In this paper,a program based on axisymmetric thermal elasto-plastic finite element method has been developed.The variation of material property against temperature has been taken into consideration in this program.As an example,a repair welding specimen was analized.The results show that this program is a useful tool for analysing thermal elasto-plastic stresses under axisymmetric condition.
