Structural Health Monitoring of 2D Plane Structures

This paper presents the application of observability technique for structural system identification 2D models. Unlike previous applications this method, unknown variables appear both in numerator and denominator stiffness matrix system, making problem non-linear impossible to solve. To fill gap, new changes are proposed linearize equations. In addition, illustrate procedure into a detailed mathematical analysis is presented. Finally, validate applicability mechanical properties state-of-the-art plate numerically determined.
