Nozzle Stress Analysis

Presented by Daniel W. Spring, Ph.D.

Quantifying stresses at nozzle-to-shell junctions on equipment subjected to supplemental loads is essential when designing pressure-retaining components in the petrochemical, chemical, and nuclear industries. Accurately and efficiently predicting the stress state at nozzle-to-shell junctions is an important aspect of understanding the propensity for failure from plastic collapse and the potential for initiation of crack-like flaws, which could lead to brittle fracture. The intent of this webinar is to highlight and discuss many of the simplified methods that have been proposed for determining the elastic stresses at nozzle-to-shell junctions due to internal pressure and external piping loads.
