Title:

A NEW DAMAGE IDENTIFICATION APPROACH BASED ON A CONTINUUN DAMAGE MODEL
|
|
Summary :
|
IN THIS PAPER A NEW APPROACH BASED ON A CONTINUUM DAMAGE MODEL AIMING TO DETECT AND LOCATE STRUCTURAL DAMAGE IS PRESENTED.
THE ALGORITHM TAKES INTO CONSIDERATION THAT THE AVAILABLE SPECTRAL INFORMATION IS PARTIAL, I.E., CONSIDERS AS ENTRIES SOME MEASURED MODES CONTAINING ONLY A SET OF MEASURED DEGREES OF FREEDOM.
THE PROBLEM S FORMULATION IS SUCH THAT THE ORIGINAL PHYSICAL CONFIGURATION OF THE ANALYTICAL MODEL, CONNECTIVITY AND SPARSITY, IS PRESERVED, WHICH PLAYS AN IMPORTANT ROLE IN DAMAGE IDENTIFICATION.
SOME EXAMPLES APLLIED TO KABE S PROBLEM (KABE, 1985) ARE PRESENTED AND THE RESULTS ARE COMPARED WITH THE RESULTS OBTAINED BY ZIMMERMAN & KAOUK (1992) TO THE SAME PROBLEM.
KEYWORDS: DAMAGE IDENTIFICATION, CONTINUUM DAMAGE MODEL, FINITE ELEMENT MODEL |
