Damage identification using inverse methods.

This paper gives an overview of the use of inverse methods in damage detection and location, using measured vibration data. Inverse problems require the use of a model and the identification of uncertain parameters of this model. Damage is often local in nature and although the effect of the loss of stiffness may require only a small number of parameters, the lack of knowledge of the location m...

Damage identification in beams using inverse methods

Beams, made of brittle materials like concrete or cement, show increasing crack development during their service life due to mechanical and environmental loadings. This local damage can be translated into a reduction of the local bending stiffness. Stiffness modifications, while assuming constant mass distribution, can be observed by monitoring the vibrational behavior of the beam. In this pape...

Acoustic Model Identification Using Inverse Model

Sound measured at various points around the environment can be evaluated by a series of multi-pole sources and their acoustic strength can be acquired. In this numerical study, a method, called the inverse method, was examined to achieve this goal. A variety of arrangements of different sources were considered and the acoustic strength of these sources was acquired. Through the application of t...

Damage Assessment using an Inverse Fracture Mechanics approach

This paper studies the application of an inverse methodology for problem solving in fracture mechanics using the finite element analysis. The method was applied to both detection of subsurface cracks and the study of propagating cracks. The procedure for detection of subsurface cracks uses a first order optimization analysis coupled with a penalty function to solve for the unknown geometric par...

Solving Inverse Problems in Structural Damage Identification

Accurately identifying damage is difficult after an extreme event since damage often cannot be directly measured. Sensors, however, can collect data that reflects damage by measuring changes in structural response. Therefore, damage identification becomes an inverse problem in which the goal is to find system properties using limited response information. The inverse problem is formulated as an...
