Determinação da fadiga em estruturas metálicas soldadas submetidas a solicitações dinâmicas
… is determined by the Miner's rule, applying the Stress Concentration Factors (SCF) for the hot-spot stress determination. A computer program has been developed, using FORTRAN language and implemented in the Burroughs 6700. This program allows the determination of linear systems response to …

EFFECT OF WELD-TOE GRINDING ON FATIGUE LIFE BASED ON THEORY OF CRITICAL DISTANCE
… geometries and notches to evaluate the fatigue stresses in real welded components. With the adoption of the theory of critical distance, the calculated stress is closer to the maximum principal stress of the weld toe determined by the finite element analysis, compared with the nominal stress and …

Optimization of Rib-To-Deck Welds for Steel Orthotropic Bridge Decks
Orthotropic steel deck has been widely used over the decades especially on long-span bridges due to its light weight and fast construction. However fatigue cracking problems on the welds have been observed in many countries. Rib-to-deck welds need special care since they are directly under wheel …

A geometric method of fatigue SCF and fracture SIF assessment
… a novel geometric methodology to evaluate the stress intensity and stress concentration factors (SIF and SCF). The background and special theory was developed to give: 1. A better understanding of the singularities that commonly occur in sharp corners in ship connection details; 2. A quicker …
