Assessment of structural damage by sensitivity of modal strain energy based on an efficient optimization function
an improved sensitivity of modal strain energy. At first, damage localization approach in dynamic systems is formu-lated by fundamental concept of modal strain energy (MSE) to precisely locate the eventual damages. Subsequently, a new optimization function...
Structural damage identification by sensitivity of modal strain energy based on optimization function
is presented by sensitivity of modal strain energy and using a new model updating optimization function. First, damage localization in the dynamic structures is formulated by fundamental modal strain energy (MSE) to precisely locate the eventual damage of a...
Early damage detection in structural health monitoring by a sensitivity method and DBSCAN clustering
sensitivity function regarding modal strain energy
(MSE) is proposed to use as a novel damage-sensitive feature. The sensitivity function is
based on proposing a new equation of modal sensitivity and using the presented equation in...
Structural damage detection by a new iterative regularization method and an improved sensitivity function
A new sensitivity-based damage detection method is proposed to identify and estimate
the location and severity of structural damage using incomplete noisy modal data. For
these purposes, an improved sensitivity function of modal strain...
