Fatigue life assessment of welded structures based on fracture mechanics

A. Krasovskyy, A. Virta

Even though modern welding technology has improved, initial defects on weld notches cannot be avoided. Assuming the existence of crack-like flaws after the welding process, the…

Experimental study of loosening behavior of plain shank bolted joint under dynamic loading

Shriram Dravid, Kartikeya Triphati, Manoj Chouksey

Bolted joints are commonly used to connect structural members. These joints can be disassembled whenever required. Various types of washers are used between nut and the connected…

Multi-length scale computational analysis of roller-bearing premature failure in horizontal-axis wind turbine gear boxes

M. Grujicic, V. Chenna, R. Yavari, R. Galgalikar, J.S. Snipes, S. Ramaswami

To make wind energy (one of the alternative-energy production technologies) economical, wind-turbines (convertors of wind energy into electrical energy) are required to operate…

Structural integrity assessment of H2S storage tanks using acoustic emission and ultrasonic techniques

C. K. Mukhopadhyay, T.K. Haneef, T. Jayakumar, G.K. Sharma, B.P.C. Rao

The purpose of this paper is to present the results of acoustic emission (AE) and ultrasonic inspection of two H₂S storage tanks carried out in a heavy water plant, in order to…

Damage tolerance of composite T-sections made of cost-effective carbon fibre preforms

Martin Kadlec, Robin Hron, Timo Grieser

T-sections of carbon fibre-reinforced composites are prone to delamination because they lack reinforcement through their thicknesses. The purpose of this paper is to present the…

Impact of plasticity generated by Rayleigh waves on the residual stress behavior of structural components subjected to laser peening

Anoop Vasu, Ramana V. Grandhi

The impact of laser peening on curved geometries is not fully comprehended. The purpose of this paper is to explain the action of laser peening on curved components (concave and…

Micromechanical study of the effect of inclusions on fatigue failure in a roller bearing

Michele Cerullo, Viggo Tvergaard

– The purpose of this paper is to carry out a set of micromechanical analyses to study the effect of small inclusions on fatigue life of wind turbine bearings.

Numerical study of fractured sandwich beams with homogenous or FGM faces under three point bending

Simonidis D. Vartholomaios, Efstathios E. Theotokoglou

In this study composite and sandwich beams with homogeneous core and homogeneous or Functional Graded Materials (FGM) faces under three point bending have been confronted. The…
