The present study investigated the strain response of a distributed optical fiber sensor (DOFS) sealed in a groove at the surface of a concrete structure using a polymer adhesive and aimed to identify optimal conditions for crack monitoring. A finite element model (FEM) was first proposed to describe the strain transfer process between the host str...
We investigate the use of a second-order cone programming (SOCP) framework for computing complex 3D steel assemblies in the context of elastoplasticity and limit analysis. Displacement and stress-based variational formulations are considered and appropriate finite-element discretization strategies are chosen, yielding respectively an upper and lowe...
A number of structures worldwilde are known to suffer from chemically induced expansion of the concrete. The proposed benchmark includes two sets of problems : on the material scale concrete specimens, and at the structural scale.
A numerical model is proposed to compute the eigenmodes and the forcedresponse of multilayered elastic spheres. The main idea is to describe analyti-cally the problem along the angular coordinates with spherical harmonics andto discretize the radial direction with one-dimensional finite elements. Theproper test function must be carefully chosen so ...
Finite element models combined with animal experimental models of spinal cord injury provides the opportunity for investigating the effects of the injury mechanism on the neural tissue deformation and the resulting tissue damage. Thus, we developed a finite element model of the mouse cervical spinal cord in order to investigate the effect of morpho...
This study aims at modelling the suction bucket foundation in clay from full finite element analyses to simplified macro-element. To ensure the reliability of finite element simulation results as much as possible, two well-known constitutive models, the Modified Cam-Clay model (MCC) and the Hardening Soil model (HS), are adopted respectively for th...

The computation of the eigenmodes of solid spheres is a classical problem in mechanics solved more than a century ago by Lamb. This topic has found many applications in geophysics, composites structures and non-destructive testing. The eigenmodes are the solutions of a dispersion relationship which can be obtained analytically. However, numerical m...
