Ductile fracture resistance of the weld metal and heat affected zone in a HSLA steel welded joint
(19th European Conference on Fracture: Fracture Mechanics for Durability, Reliability and Safety, ECF 2012, 2012)
Ductile damage development in welded joints of high strength low alloyed (HSLA) steel NIOMOL 490K was examined experimentally and analyzed using the micromechanical approach. Single-edge notched bend (SENB) specimens, cut ...
Damaged welded pipes for oil and gas rigs exposed to internal pressure - Failure estimation
(19th European Conference on Fracture: Fracture Mechanics for Durability, Reliability and Safety, ECF 2012, 2012)
The paper deals with the integrity assessment of API J55 steel casing pipes for drilling rigs, manufactured by high frequency contact welding procedure. The influence of corrosion defects on the pipeline load carrying ...
