Numerical Comparison of Cruciform weld and Butt weld simulation and a Study of Fracture Mechanics on Two Types of Welds

Benattou Bouchouicha, Malika Tirenifi, El Bahri Ould Chikh, Ahmed Bensari

The modeling of the welding is desirable to guess the deformation of the components during manufacture, the position and the magnitude of maximum residual stresses and to envisage metallurgical effects in specific zones. The welding are…

Review of Current Developments on High Strength Pipeline Steels for HIC Inducing Service

Ehsan Entezari, Jorge Luis González-Velázquez, Diego Rivas López, Manuel Alejandro Beltrán Zúñiga, Jerzy A. Szpunar

Nowadays, an increasing number of oil and gas transmission pipes are constructed with high-strength low alloy steels (HSLA); however, many of these pipelines suffer from different types of hydrogen damages, such as hydrogen-induced…

Influence of material inhomogeneity and non-linear mechanical behavior of the material on delamination in multilayered beams

Victor Rizov

The delamination fracture in four-point bending beams made of adhesively bonded lengthwise vertical layers is studied assuming that each layer exhibits smooth material inhomogeneity along the width and length of the layer. The study aims…

The Effects of Shear on Mode II Delamination: A Critical Review

Paolo Sebastiano Valvo

The paper focuses on the effects of shear deformation and shear forces on the mode II contribution to the energy release rate in delaminated beams. A critical review of the relevant literature is presented, starting from the end-notched…

Size effect on the fracture resistance of rough and frictional cracks

Andrea Spagnoli, Andrea Carpinteri, Michele Terzano

Elastic fracture mechanics commonly defines the fracture resistance of brittle materials within an idealised picture of planar and traction free cracks. An efficient approach to describe the interface conditions in real cracks, such as…
