Integrated structure for a resonant micro-gyroscope andaccelerometer
Journal Title: Frattura ed Integrità Strutturale - Year 2014, Vol 8, Issue 29
Abstract
This paper presents the study of the mechanical behavior of a microstructure designed to detectacceleration and angular velocity simultaneously. The new resonant micro-sensor proposed, fabricated by theThELMA© surface-micromachining technique, bases detection of two components of external acceleration (onein-plane component and one out-of plane component) and two components of angular velocity (roll and yaw)on the variation of frequency of several elements set in resonance. The device, despite its small dimensions,provides a differential decoupled detection of four external quantities thanks to the presence of four slenderbeams resonating in bending and four torsional resonators.

The theory of critical distances applied to problems in fracture and fatigue of bone
The theory of critical distances (TCD) has been applied to predict notch-based fracture and fatigue in a wide range of materials and components. The present paper describes a series of projects in which we applied this a...
Damage localization and rupture with gradient damage models
We propose a method of construction of non homogeneous solutions to the problem of traction of a bar made of an elastic-damaging material whose softening behavior is regularized by a gradient damage model. We show...
A non-linear procedure for the numerical analysis of crack development in beams failing in shear
In this work, a consistent formulation for the representation of concrete behavior before and after cracking has been implemented into a non-linear model for the analysis of reinforced concrete structures, nam...
Random non-proportional fatigue tests with planar tri-axial fatigue testing machine
Complex stresses, which occur on the mechanical surfaces of transport machinery in service, bring a drastic degradation in fatigue life. However, it is hard to reproduce such complex stress states for evaluating t...
