A comparison between S-N Logistic and Kohout-Věchet formulations applied to the fatigue data of old metallic bridges materials

Joelton Fonseca Barbosa, José A.F.O. Correia, Pedro Montenegro, Raimundo Carlos Silverio Freire Júnior, Grzegorz Lesiuk, Abílio M.P. De Jesus, Rui A.B. Calçada

A new formulation of a Logistic deterministic S-N curve is applied to fatigue data of metallic materials from ancient Portuguese riveted steel bridges. This formulation is based on a modified logistic relation that uses three parameters to…

On the relationship between crack initiation angle and loading equivalent angle for asymmetric Three-Point Bend Specimens under mixed-mode I/II loading based on GMPZR criterion

Mujebur Rehaman, Manjunath Patel Gowdru Chandrashekarappa, Mohan T R, Shashidhar K Kudari, Sharanaprabhu C M

In this work, the prediction of crack initiation angle (θ_o) under mixed mode (I/II) load is estimated from the generalized minimum plastic zone radius (GMPZR) criterion. The paper presents a detailed study on the crack-tip plastic core for…

Fatigue experimental characterisation of brazed joints in aluminium microchannel heat exchangers

Federico Milan, Sandro Ortolano, Gian Luca Gori, Denis Benasciutti, Enrico Salvati

Brazing is a widely employed joining technique for aluminium components due to its cost-effectiveness and compatibility with complex geometries. However, the structural integrity of brazed joints under cyclic loading remains a scarcely…

Using XFEM to Predict the Damage with Temperature of the Steel Pipe Elbows under Bending and Pressure loading

Nourddine Hammadi, Moahmed Mokhtari, Habib Benzaama, Kouider Madani, Abdelkader Brakna, Elamine Abdelouahed

The pipes, during their service, are subjected to accumulated loads such as internal pressure and that of the soil. The latter considerably accelerate their damage. In this work, the bending moment stress of API 5L X70 category steel…
