ABSTRACT The mechanical performances of the interface between the concrete and the fiber reinforced polymer (FRP) are investigated using nonlinear finite element method (FEM) in this paper. The paper focuses [...]

ABSTRACT In this paper, a constitutive law describing the wood behaviour, as elasto-plastic orthotropic material with 3D finite element model, is presented. Anisotropic elasto-plastic constitutive law with hardening associated with [...]

Abstract This paper summarises the results of an experimental and numerical study of precast reinforced composite sandwich panels. Full-scale tests were carried out to determine their axial strength capacity. Load--deformation [...]

One of the conventional ways to inspect deformable parts is to compare a data model against its nominal CAD model. This process assumes that the data model includes most of the visible surface including regions around fixation points where the part will be attached to others. This paper proposes a method to inspect deformable part by acquiring only regions that need to be inspected and then by applying to the CAD model a non-linear deformation using FEM modeling to minimize the differences with the partial views. The process first starts with a rigid alignment followed by an iterative process where the part's deformation is iteratively matched to the partial views. In this scheme, fixation points are not digitized and the non-linear part deformation calculations are estimated by interpolation. Test results performed on real parts compares favorably to deformation calculations using complete data model from the point-of-view of speed and accuracy.

ABSTRACT Important characteristics for temporary structures include ease of deployment, simple erection, and minimal shipping volume and weight. The use of inflatable fabric members (i.e. airbeams) directly satisfies these needs [...]

ABSTRACT In order to study the ionic diffusivity of cement-based materials, a numerical model is proposed based on cement hydration and a microstructure model HYMOSTRUC3D, coupled with random walk algorithm [...]

ABSTRACT The durability of most porous building materials is strongly related with moisture and salt transport mechanisms. The main storage parameter which describes the hygral state of any porous material [...]
