Defects in structure alter its dynamic characteristics. They reduce the service life which may lead to catastrophic failure. These defects may be characterized by changes in their dynamic parameters. Thus, detection of defects using reliable and effective method is an important consideration to guarantee the component safety and prolong the service life of the structure and hence save costs. This...

Finite element model updating with incomplete complex modal data and structural parameters coupled with mass, stiffness and damping matrixes simultaneously for unsymmetrical damping system using optimization method is presented. By the use of finite element software-NASTRAN and mathematical tool-MATLAB model updating based on complex eigenvalue sensitivity analysis is successfully accomplished in...
