Stress Intensity Factor Solutions for CTS Mixed Mode Specimen

Fernando Ventura Antunes, Ricardo Branco, José António Martins Ferreira, Luís Borrego

The Compact Tension Shear (CTS) specimen is used to study fracture and fatigue under mixed mode I/II loading conditions. Existing K solution was developed for fracture studies and it does not consider the effect of crack deflection. The…

Experimental and numerical study on mechanical properties of aluminum alloy under uniaxial tensile test

O. Daghfas, A. Znaidi, A. Ben Mohamed, R. Nasri

The main objective is to model the behavior of 7075 aluminum alloy and built an experimental database to identify the model parameters. The first part of the paper presents an experimental database on 7075 aluminum alloy. Thus, uniaxial…

Fatigue life prediction of casing welded pipes by using the extended finite element method

Ljubica Lazi? Vuli?evi?, Aleksandar Raji?, Aleksandar Grbovi?, Aleksandar Sedmak, Živ?e Šarko?evi?

The extended finite element (XFEM) method has been used to simulate fatigue crack growth in casing pipe, made of API J55 steel by high-frequency welding, in order estimate its structural integrity and life. Based on the critical value of…

Crack detection in beam-like structures by nonlinear harmonic identification

Paolo Casini, Fabrizio Vestroni, Oliviero Giannini

The dynamic behavior of beam-like structures with fatigue cracks forced by harmonic excitation is characterized by the appearance of sub and super-harmonics in the response even in presence of cracks with small depth. Since the amplitude…

Elastic-viscoplastic deformation models of salt rocks

Alexander Baryakh, Andrey Tsayukov

Results of secondary creep tests for salt rock specimens were mathematically described. Elastic-viscoplastic modeling of viscous properties of salt rocks was based on elastoplastic models using a non-associated Mohr-Coulomb plastic flow…

Analytical and numerical analysis on the collapse modes of least-thickness circular masonry arches at decreasing friction

Giuseppe Cocchetti, Egidio Rizzi

Departing from pioneering Heyman modern rational investigations on the purely-rotational collapse mode of least-thickness circular masonry arches, the hypothesis that joint friction shall be high enough to prevent inter-block sliding is…
