Analysis of Finite Element Simulation of Crack Initiation in Dispersion Fuel Particle

With the finite element method,the mutli-bubble fuel particle model was established and the stress distribution of the fuel particle was analyzed under the pressure of the fission gas bubbles(FGBs).The effect of the bubble location on the max tensile stress was summarized at the inner-border of bubble.And the crack initial location was found out while associated […]

Analysis of weld crack of spherical hinge support ear plate in Egang 130t converter

The welding seam cracking of the supporting bolt support ear plate in a converter of Egang is repeated, and the joint shaft between the ear plate and the supporting bolt is often worn. Based on field test and finite element simulation analysis, the causes of weld cracking are analyzed deeply. The results show that due […]
