Abstract
  The present study deals on the geometry effects of the spherical pressure vessel(SPV) and the crack configuration on the variation of the stress intensity factor (SIF) through the crack line. The pressurized vessel is subjected to the pressure and thermal gradient (thermo-mechanical loading). The 3D ...  Read More

Abstract
  Stimulation of hydrocarbon wells with matrix acidizing operation is among the most common operations to stimulate the formation in order to remove the skin and improve the productivity index. But corrosion of equipment, including casings, is one of the most important concerns. In the present paper, the ...  Read More
