Mechanical Heterogeneity and Geometry Effects on Yield Load Solutions
The paper deals with numerical solutions for the mismatch yield load of three points bend (3PB) fracture toughness specimen with the weld joint cracked in the middle. Effects of difference in yield strength of materials in the joint as well as geometrical influence parameters on the yield load value have been analyzed. The results for mismatch yield load are given in the form of diagrams depending on the crack depth ratio a/W and slenderness of the weld (W-a)/H. The magnitude and shape of the yielding zones have been compared for the specimens with the constant value of a/W=0, 5, but with different weld root widths 2H.
