The Experimental Study and Numerical Estimation of Fracture Toughness of Heterogeneous Welded Joints

Abstract:

In this paper the mechanical heterogeneity of welded joints was studied. The experimental results show that the mechanical properties and fracture toughness vary significantly in zones of welded joint. To estimate the fracture parameter J-integral a numerical finite-element model based on the random variation of yield strength was proposed.
