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…

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…

Stress triaxiality and Lode angle along surfaces of elastoplastic structures

Expressions for the stress triaxiality and the Lode angle along surfaces of elastoplastic structures are established in case of monotonic loading. The stress triaxiality is shown to be governed by the accumu- lated plastic strain when traction free…
