Fatigue Lifetime Assessment of HFMI‐Treated Welded Joints According to the Peak Stress Method
Fatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 3, Page 790-819, March 2026.ABSTRACT High‐frequency mechanical impact (HFMI) is an effective post‐weld treatment that enhances fatigue strength by inducing compressive residual stresses, localized strain hardening, and increasing weld toe radii. The peak stress method (PSM) was recently extended to evaluate the fatigue strength of HFMI‐treated steel joints under uniaxial loading ...

A method for LEFM analysis of RPV during SBLOCA [PDF]
International Journal of Pressure Vessels and Piping, 1986 Abstract A somewhat simplified two-dimensional linear elastic fracture mechanics (LEFM) model of the beltline of a reactor pressure vessel is presented. The fracture mechanics model used tends to be conservative in the sense that it ignores possible beneficial effects of warm prestressing and cladding. For LEFM studies that require a large number of
