Plasticity and damage analysis of metal hollow sphere structures under dynamic compressive loading

Luiz Antônio Bragança da Cunda, Branca Freitas de Oliveira, Guillermo Juan Creus

As compared with homogeneous metals and alloys, cellular metals provide low density, high specific stiffness, high energy absorption and good damping, thus being interesting…

Constraint effect on the slow crack growth in polyethylene

Pavel Hutar, Michal Zouhar, Eva Nezbedova, Jiri Sadilek, Jan Zidek, Lubos Nahlik, Zdenek Knesl

From the practical point of view, most relevant damage to high density polyethylene (HDPE) structures is caused by slow crack growth. Therefore, detailed information about this…

GFRP sandwich panels with PU foam and PP honeycomb cores for civil engineering structural applications: Effects of introducing strengthening ribs

J.R. Correia, M. Garrido, J.A. Gonilha, F.A. Branco, L.G. Reis

The purpose of this paper is to present experimental investigations on the structural behaviour of composite sandwich panels for civil engineering applications. The performance of…

Crack propagation in a welded polyolefin pipe

Martin Sevcik, Pavel Hutar, Lubos Nahlik, Ralf Lach, Zdenek Knesl, Wolfgang Grellmann

The purpose of this paper is to study the effect of the material inhomogeneity on crack behavior initiated both axially and circumferentially in or near the butt weld and to…

A procedure to derive probabilistic fatigue crack propagation data

José A.F.O. Correia, Abilio M.P. de Jesus, Alfonso Fernández‐Canteli

Recently, a new class of fatigue crack growth models based on elastoplastic stress‐strain histories at the crack tip region and strain‐life fatigue damage models have been…

Fatigue crack propagation behaviour in thick steel weldments

C.M.C. Albuquerque, R.M.C. Miranda, V. Richter‐Trummer, M.A.V. de Figueiredo, R. Calçada, P.M.S.T. de Castro

The purpose of this paper is to study the fatigue crack growth (FCG) behaviour of the steel and weldments of a railway bridge.
