Estimating the fatigue behavior of welded joints in the VHCF regime

A. Krasovskyy, D. Bachmann

The present work aims to deal with a very high cycle fatigue (n=10⁹ cycles) of gas metal arc welded joints, subjected to a multiaxial and non‐proportional loading. Different…

An assessment of a strain‐life approach for fatigue crack growth

Mohammad Hadi Hafezi, N. Nik Abdullah, José F.O. Correia, Abílio M.P. De Jesus

Fatigue crack growth models based on elastic‐plastic stress‐strain histories at the crack tip region and strain‐life damage models have been proposed. The UniGrow model fits this…

Fibre laser cladding of turbine blade leading edges: the effect of specific energy on clad dilution

B. Valsecchi, B. Previtali, E. Gariboldi

The present work aims at developing the laser cladding technology by means of an active fiber laser source applicable for hardfacing of martensitic steel turbine blades. It also…

Fatigue life prediction of scratch damaged shot peened components

R.A. Cláudio, J.M. Silva, J. Byrne

This paper aims to present a methodology, based on traditional approaches, to predict the fatigue life and non‐propagating cracks of shot peened components and the damaging effect…

Theory and experimental method to determine bonding strength envelope of bi‐material interface

M.A.K. Chowdhuri, Z. Xia

It is well known that stress singularity may exist at the edges of a bonded bi‐material interface due to the discontinuity of material properties. This stress singularity causes…

Fatigue damage in GFRP

C. Colombo, F. Libonati, L. Vergani

Composite materials are increasingly used in the structural and mechanical fields, thanks to their high strength‐to‐weight ratios and the possibility of tailoring them to meet…

Finite element modeling of mandrel speed in cold expansion process

Khalil Farhangdoost, Abbas Hosseini

The bodies of aircraft structures have a lot of fastener holes and under different situations these holes bear external forces, which cause a tensile stress on the surface that…

Effect of arbitrary bi‐material combination and bending loading conditions on stress intensity factors of an edge interface crack

Kazuhiro Oda, Xin Lan, Nao‐Aki Noda, Kengo Michinaka

The purpose of this paper is to compute the stress intensity factors (SIFs) of single edge interface crack for arbitrary material combinations and various relative crack lengths…

Effect of substrate structure on properties of nitrided layers formed on pure iron

N. Lecis, M. Vedani, S. Farè

This paper aims to investigate the structure and scratch resistance properties of gas nitrided pure iron samples.
