Detection of Uniaxial Fatigue Stress under Magnetic Flux Leakage Signals using Morlet Wavelet

Syed Muhamad Firdaus, Azli Arifin, Shahrum Abdullah, Salvinder Singh Karam Singh, Noorsuhada Md Nor

This paper demonstrates the application of continuous wavelet transform technique for magnetic flux leakage signal generated during a uniaxial fatigue test. This is a consideration as the magnetic signal is weak and susceptible to being…

Effect of yield stress on fatigue crack growth

Fernando Ventura Antunes, Micael Frias Borges, Pedro Prates, Ricardo Branco, Marta Oliveira

Abstract. Fatigue crack growth (FCG) depends on loading, geometry and also material properties. Since FCG is supposedly linked to crack tip plastic deformation, material’s yield stress, Y₀, is an important parameter. The main objective…

A nonlocal elasticity theory to model the static behaviour of edge-cracked nanobeams

Daniela Scorza, Andrea Carpinteri, Camilla Ronchei, Andrea Zanichelli, Raimondo Luciano, Sabrina Vantadori

In the present paper, the mechanical behaviour of edge-cracked nanobeams under Mixed-Mode loading is analytically investigated by means of the Stress-Driven nonlocal model. Firstly, the proposed formulation is outlined, and then applied to…

Use of a gray level co-occurrence matrix to characterize duplex stainless steel phases microstructure

F. R. Renzetti, L. Zortea

Duplex stainless steels are widely used in industry. This is due to their higher strength compared to austenitic steels and to their higher toughness than ferritic steels. They also have good weldability and high resistance to stress…
