Modal Analysis via Finite Element Method // Klein Surface

Modal analysis is the study of the dynamic properties of structures under vibrational excitation and it uses a structure’s overall mass and stiffness to find the various periods that it will naturally resonate at. These periods of vibration are important in terms of earthquake engineering of the building. If the structural vibration is of concern in the absence of time-dependent external loads, a modal analysis is performed. Because the structural frequencies are not known a priori, the finite element equilibrium equations for this type of analysis involve the solution of homogeneous algebraic equations whose eigenvalues correspond to the frequencies, and the eigenvectors represent the vibration modes.
