The present paper discusses the estimation of the stress state of Rolling Contact Fatigue (RCF) cracks according to linear elastic fracture mechanics, by making use of the weight function to obtain the Stress Intensity Factors. The weight functions a

In Eurocode 3, a design rule is given for predicting the ultimate resistance of the net cross-section at bolt holes. This is based on the average stress evaluated in the net cross-section, and contains both a reduction factor of 0.9 and a partial fac

This paper presents a probabilistic framework to derive the safety factors for fatigue of steel and composite steel concrete road bridges. Engineering models are used for the design and the safety factor is derived in such a way that the design meets

In the last decades, many catastrophic events due to the rupture of metallic components have been traced back to fretting fatigue. In order to avoid failures due to such a contact phenomenon, many researchers have focused on fretting fatigue behaviou

Sometimes, structural components experience service conditions that have not taken into account at the design stage. In this study, the effects of the boundary conditions on the crack propagation life have been evaluated using the modified Virtual Cr

Before bolts were invented, hot-riveting was employed as technological process to produce built-up structural members of steel structures. Nowadays, these structures being still in service and susceptible to fatigue failure, they need to be assessed

This present paper concerns the application of probabilistic fatigue life prediction models based on S–N curves aiming at the estimation of the safety level for a non-load carrying cruciform joint. The safety level is expressed in terms of the reli

Propagation of weld toe cracks under cyclic loading is often predicted using fracture mechanics. In as welded condition, most of the propagation life is spent as a short crack, which is known to behave differently than a long crack. Several studies h

Probabilistic fatigue life prediction models of welded steel joints are often used to estimate the level of safety, which is given in terms of the probability of failure or the reliability index as a function of the applied load cycles. Prediction mo
