Anisotropic damage modeling of concrete materials

An anisotropic damage model is proposed for concrete materials. As required by thermodynamics a single damage variable, tensorial, is considered for any loading: as a state variable it represents the micro-cracking pattern whatever the loading sign…

Design and Simulation of Bistable Microsystem with Frequency-up conversion effect for Electrostatic Energy Harvesting

This work is dedicated for the study of energy harvesters implemented in form of microelectromechanical systems (MEMS) used to harvest ambient vibrations for powering standalone electronic devices. The previewed application is to power a leadless…

The Constitutive Relation Error method: a general verification tool

This chapter reviews the Constitutive Relation Error method as a general verification tool which is very suitable to compute strict and effective error bounds for linear and more generally convex Structural Mechanics problems. The review is focused…

Drying, cracks and shrinkage evolution of a natural silt intended for a new earth building material. Impact of reinforcement

Series of drying tests are carried out on natural silt intended for the preparation of new raw earth concrete. This technique is different from rammed earth. The study treats the drying of various formulations of the natural silt with and without…

Internal friction angle variation in a kaolin/montmorillonite clay mix and microstructural identification

This paper presents an extensive study of a variable model clayey material, made of mixtures (in different proportions) of two mineralogically different clays. The basic clays are montmorillonite (Greek clay) characterised by a high plasticity, and…

Toward an integrated seismic risk assessment for nuclear safety improving current French methodologies through the SINAPS@ research project

The Tohoku earthquake and associated tsunami in March 2011 caused a severe nuclear accident at the Fukushima Daiichi Nuclear Power Plant, where level 7 (International Atomic Energy Agency (IAEA) – INES scale) meltdown at three reactors occurred. The…

On the introduction of a mean stress in kinetic damage evolution laws for fatigue

An evolutive mean value of z is defined for complex loadings. It is shown to be independent from the loading shape and it tends toward the classical mean value zmean for a periodic loading. The proposed definition applies to quantities encountered…
