Aetosaurs are quadrupedal archosaurs that had a worldwide distribution during the Late Triassic. They had small heads relative to their body size and a long tail, and they are characterized by a dorsal and ventral carapace formed by ornamented and ar

In this paper we discuss the finite element modeling of Composite Overwrapped Pressure Vessels (COPVs) which are used in the aerospace industry, when high strength/weight ratios are required, for containers filled with pressurized fluids. The COPVs t

In this work we present a computational framework for the parallel simulation of hydraulic fracturing processes. The simulation algorithm is built upon the staggered coupling of a fluid model that describes the viscous flow in the fractured domain an

An analysis of metal forming processes with axial geometry is performed by an expansion in Fourier series on the circumferential direction. For that purpose, an incremental form is presented on the basis of the flow formulation. For every increment o

A new two-scale finite element formulation was developed for modeling J2 plastic deformation processes (2D) in which shear band localizations take place. The formulation is based on the use of embedded strong discontinuity modes, which are triggered

Using finite element models it is possible to determine the cross-over external pressure of different pipeline arrestor designs. In this paper these finite element models are discussed and validated by comparing their results with experimental determ

The modelling of complex 3D metal forming processes using the flow formulation, implemented via the pseudo-concentrations technique, requires the development of robust computational strategies for dealing with the velocity and pseudo-concentration bo
