Numerical Investigation of Strength Mismatch Effect on Ductile Crack Growth Resistance in Welding Pipe

Numerical Investigation of Strength Mismatch Effect on Ductile Crack Growth Resistance in Welding Pipe

The effect of strength mismatch (ratio between the yield stress of weld metal and base metal, <i>M<sub>y</sub></i>) on the ductile crack growth resistance of welding pipe was numerically analyzed. The ductile fracture behavior of welding pipe was determined while using the si...
