Miniaturization of Compensational Spring System using the Highly Nonlinear Curved beams in MEMS

In this work an approach to minimize a non-linear system with a flat region in the force-displacement characteristics is studied. Design, simulation, fabrication and characterization of the initial system with the linear compensational spring and…

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…

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…

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…
