Earthquake and Volcano Clustering at Mono Basin (California)

D. La Marra[1], A. Manconi[2], and M. Battaglia[1]
[1]Dept of Earth Sciences, University of Rome “La Sapienza”, Roma, Italy
[2]IRPI-CNR, Strada delle Cacce, Torino, Italy

This study investigates the feedback between fault slip and dike intrusions during the Mono-Inyo eruption sequence of ~1350 A.D. (Mono Basin, California). We perform an extensive validation of 3D finite element models, implemented in the Structural Mechanics module of COMSOL ... En savoir plus

Modeling of Chloride Transport in Cracked Concrete: a 3-D Image–Based Microstructure Simulation

Y. Lu[1], E. Garboczi[1], D. Bentz[1]
[1]National Institute of Standards and Technology, Gaithersburg, MD, USA

The prediction of concrete materials service life is not easy, because the complex heterogeneous microstructure and the random nature of concrete materials. Study the presence of cracks in concrete and their effect on coupled reaction and transport are of great interest in civil ... En savoir plus

Poroelasticity Benchmarking for FEM on Analytical Solutions

E. Holzbecher[1]
[1]Georg-August Universität Göttingen, Göttingen, Germany

We examine the poroelastics mode, which couples hydraulics and mechanics by some basic benchmarks. For cases with analytical solutions we check the accuracy for changing meshes and calculate the convergence rate. En savoir plus

Radionuclide Transport Through Different Routes Near a Deposition Hole for Spent Nuclear Fuel

V-M.S. Pulkkanen[1]

[1]VTT, Technical Research Centre of Finland, Espoo, Finland

Radionuclide transport modeling is a part of the research concerning geological disposal of spent nuclear fuel. Typically, the transport models near a single deposition hole focus on the reactions of nuclides, while the model geometry and the flow of groundwater are often simplified. In ... En savoir plus

The Microplane Model for Concrete in COMSOL

A. Frigerio
RSE S.p.A.
Milan, Italy

The safety of large civil structures is often evaluated by means of numerical models based on the Finite Element Method. In this frame, the choice of a constitutive law able to represent the complex mechanical behaviour of concrete is a key point. This paper deals with a detail ... En savoir plus

The Non Linear Behavior of the Microplane Model in COMSOL

A. Frigerio[1]
[1]RSE, Milano, Italy

The safety of large civil structures is often evaluated by means of numerical models based on the Finite Element Method (FEM). In the last year, the elastic behavior of the Microplane Model was implemented in COMSOL because it is a promising approach able to overcome the limit typical of ... En savoir plus

Gravitational Collapse of Rectangular Granular Piles

M.H. Babaei[1], T. Dabros[2], S.B. Savage[3]
[1]Ocean, Coastal, and River Engineering, National Research Council of Canada, Ottawa, ON, Canada
[2]Natural Resources Canada, CanmetENERGY, Devon, AB, Canada
[3]Department of Civil Engineering & Applied Mechanics, McGill University, Montreal, QC, Canada

In this study, the dam-break type two-dimensional gravitational collapse of rectangular granular piles in air was numerically studied. The frictional behavior of the material was based on the von-Mises model with the Mohr-Coulomb yield surface leading to pressure and strain-rate ... En savoir plus

Using COMSOL for the Transport Modelling of Some Special Cases in a Bentonite Buffer in a Final Repository for Spent Nuclear Fuel

M. Olin[1], V-M. Pulkkanen[1], A. Seppälä[1], T. Saario[1], A. Itälä[1], M. Tanhua-Tyrkkö[1], and M. Liukkonen[1]

[1]VTT, Technical Research Centre of Finland, Espoo, Finland

The bentonite barrier is an essential part of a safe spent fuel repository in granitic bedrock. In this work COMSOL Multiphysics® is used in modelling the Thermal (T), Hydrological (H), Mechanical (M) and Chemical (C) phenomena and processes taking place in a bentonite buffer. Special ...

Influence of Vickers Indenter Tip Geometry on the Macro-indentation Properties of TiAl Alloys

G. Maizza, and R. Cagliero
Politecnico di Torino
Dipartimento di Scienza dei Materiali ed Ingegneria Chimica
Torino, Italy

In this work the influence of the geometry of the Vickers indenter tip on relevant indentation properties is investigated during instrumented indentation operated in the macro range (i.e. with forces ranging from 2 to 200 N) and carried out in the case of a homogenized (i.e. heat ...
