Damage detection of structures using modal strain energy with Guyan reduction method

The subject of structural health monitoring and damage identification of structures at the earliest possible stage has been a noteworthy topic for researchers in the last years. Modal strain energy (MSE) based index is one of the efficient methods which are commonly used for dete

Model Reduction and Sensor Placement Methods for Finite Element Model Correlation

The issue of model reduction is one that must often be overcome in order to perform the necessary checks as part of the spacecraft Finite Element Model (FEM) validation process. This work compares different reduction methods; specifically the popular and long-standing Guyan metho

Generalization of Component Mode Synthesis Using Modal Differential Sub-Structure Method and Guyan Reduction(Mechanical Systems)

Non Nodal Condensation of Eigenvalue Problems

We generalize the Guyan condensation of large symmetric eigenvalue problems to allow general degrees of freedom to be master variables. On one hand useful information from other condensation methods (such as Component Mode Synthesis) thus can be incorporated into the method. On t

Modern Model Order Reduction for Industrial Applications

2 Dynamic analysis is an important part of modern simulation strategy. However, finite element models are inherently high dimensional and, as a result, their dynamic analysis is computationally expensive. For this reason, it is impossible to include a finite element model directl

Improved Dynamic Substructuring on

For solving the eigenvalue problem of a structural system having a large number of degrees of freedom the authors introduced in 6] the improved condensation method using the Rayleigh functional of the exactly condensed nonlinear eigenvalue problem. In this paper we discuss the im

Optimal Shape Control of Composite Thin Plates with Piezoelectric Actuators

Emerging technologies in microsensing, microactuation, active airfoils, turbine blades, and large, lightweight, flexible space structures can benefit from piezoelectric actuators for active shape control. Piezoelectric materials develop strain under applied voltage which induces

Next Generation Benchmark Control Problem for Seismically Excited Buildings

This paper presents the problem definition and guidelines of the next generation structural control benchmark problem for seismically excited buildings. Focusing on a 20-story steel structure representing a typical midto high-rise building designed for the Los Angeles, California
