Identification of microscale fracture models for mortar with in-situ tests

The microscale fracture modeling of concrete requires explicit descriptions of the microstructure and the fracture properties of its constituents. The identification of fracture properties of mortar was carried out by numerical analyses of two in…

Kriging metamodels for 2D finite element simulations of the settlements induced by TBM excavation in urban areas

The finite element method (FEM) is a classical approach to simulate the surface settlements induced by a tunnel boring machine (TBM). Unfortunately, for this application, the FEM is also computationally demanding. In this case, it is often useful to…

Souriau's Relativistic general covariant formulation of hyperelasticity revisited

We present and modernize Souriau’s 1958 geometric framework for Relativistic continuous media, and enlighten the necessary and the ad hoc modeling choices made since. We focus as much as possible on the Continuum Mechanics point of view and describe…

Asynchronous global-local non-invasive coupling for linear elliptic problems

This paper presents the first asynchronous version of the Global/Local non-invasive coupling, capable of dealing efficiently with multiple, possibly adjacent, patches. We give a new interpretation of the coupling in terms of primal domain…

Real-time inverse crack tracking in uncertain microstructures using PGD-based model reduction and extended Kalman filtering

Despite recent advances in sensing techniques and rapid growth of computational mechanics, it remains a challenge to monitor mechanical structures in real-time and evaluate their sustainability. In the present work, crack propagation is investigated…

Design of Artificial Neural Networks for damage estimation of composite laminates: Application to delamination failures in ply drops

This work proposes a data driven approach which utilizes Artificial Neural Networks (ANN) in conjunction with parametric non-linear finite element analysis. The aim is to provide a low cost numerical counterpart to the expensive experimental testing…

Reduced polynomial invariant integrity basis for in-plane magneto-mechanical loading

The description of the behavior of a material subjected to multi-physics loadings requires the formulation of constitutive laws that usually derive from Gibbs free energies, using invariant quantities depending on the considered physics and material…

Blind broad-band (0-10 Hz) numerical prediction of the 3-D near field seismic response of a Mw6.0 extended fault scenario: application to the nuclear site of Cadarache (France)

In this paper, physics-based numerical simulation (PBS) is employed to render a broad-band (0–10 Hz) realization of the near-field seismic response of the experimental nuclear site of Cadarache, located nearby the active Middle Durance Fault …

Validation of a new viscoelastic model for unidirectional polymer matrix composites by analytical and numerical homogenisation

The long-term response of unidirectional, fibres-reinforced, polymer matrix composites is affected by the viscoelastic behaviour of the matrix. Most composite models introduce a different relaxation function for each of the five elastic parameters…
