A = aerodynamic stiffness matrix C = speed of sound E = complex Fourier matrix f , F = physical and modal forces h = height of stream tube j = imaginary unit K, M = stiffness and mass matrices NB = number of blades P, Q = modal transformation matrices p = flow pressure Q = flow mass flux at the boundary q = generalized (modal) coordinate s = distance along the boundary T = period of flow unstea...
Building a digital twin representing the dynamical behaviour of structure requires knowledge its material and geometrical properties. While geometry, mass stiffness can often be characterised quite accurately, at least for homogeneous isotropic materials, experimental quantification structural damping is time consuming endeavour. Furthermore, chosen set-up subjects obtained values to uncertaint...
As a result of environmental and accidental actions, damage occurs in structures. The early detection of any defect can be achieved by regular inspection and condition assessment. In this way, the safety and reliability of structures can be increased. This paper is devoted to propose a new and effective method for detecting, locating, and quantifying beam-like structures. This method is based o...
