Karim Benyahi, Youcef Bouafia, Mohand Said Kachi, Sarah Benakli, Amel Hamri

This work deals with the coupling between a periodic homogenization procedure and a damage process occurring in a RVE of inclusion composite materials. We mainly seek on the one hand to determine the effective mechanical properties…

A study on the crack presence effect on dynamical behavior of higher-order Quasi-3D composite steel-polymer concrete box section beams via DQFEM

Nassim Laouche, Ahmed Saimi, Ismail Bensaid, Mouloud Dahmane, Hassen Ait Atmane

This paper presents a dynamic and critical buckling analysis of the presence of a crack of steel-polymer concrete composite beams modelled using a refined quasi 3D beam theory. The beam model is a hollow steel box section filled with a…

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…

Multi-level Uncertain Fatigue Analysis of a Truss under Incomplete Available Information

Raphael Basilio Pires Nonato

We predict the fatigue life of a planar tubular truss when geometrical parameters, material properties, and live loads are non-deterministic. A multi-level calculation uncertainty quantification framework code was designed to aggregate the…
