Nonlinear System Identification of Physical Parameters for Damage Prognosis and Localization in Structures
… thus, is to develop quantitative assessment of damage accumulation from the earliest stages of the fatigue process and to provide a structure's signature that is dependent of the damage stage. One such signature is the structure's response to forced excitation. The realization of such a goal …

Fatigue Damage Prognosis of Internal Delamination in Composite Plates Under Cyclic Compression Loadings Using Affine Arithmetic as Uncertainty Propagation Tool
… increased the effects of fatigue induced damage on their critical structural components and thus the necessity to predict the remaining life of those components. Damage prognosis, one of the least investigated fields in SHM, uses the current damage state of the system to forecast its …

Use of Response Surface Metamodels in Damage Identification of Dynamic Structures
… need for low order models capable of performing damage identification has become apparent in many structural dynamics applications where structural health monitoring and damage prognosis programs are implemented. These programs require that damage identification routines have low computational …

A Predictive Methodology for Soft Impact Damage in Jet Engines Incorporating Hybrid Composite Structures
… capturing the full range of multifaceted damage in hybrid and composite structures as they evolve throughout the forward section of a propulsion system. Effective strategies are developed within an explicit finite element framework for modeling a bird, an engine forward section, intra-ply …

High Frequency Modeling and Experimental Analysis for Implementation of Impedance-based Structural Health Monitoring
… not typically use an analytical model for basic damage identification, a model is necessary for more advanced features of SHM, such as damage prognosis, and to evaluate system parameters when installing on various structures. A model was developed based on circuit analysis of the previously …

Modeling and Experimental Analysis of Piezoelectric Augmented Systems for Structural Health and Stress Monitoring Applications
Detection, characterization and prognosis of damage in civil, aerospace and mechanical structures, known as structural health monitoring (SHM), have been a growing area of research over the last few decades. As several in-service civil, mechanical and aerospace structures are approaching or even …
