Efficient Optomechanical Mode-Shape Mapping of Micromechanical Devices. [PDF]
Micromachines (Basel), 2021 Visualizing eigenmodes is crucial in understanding the behavior of state-of-the-art micromechanical devices. We demonstrate a method to optically map multiple modes of mechanical structures simultaneously. The fast and robust method, based on a modified phase-lock loop, is demonstrated on a silicon nitride membrane and shown to outperform three ...

Shape descriptors for mode-shape recognition and model updating [PDF]
Journal of Physics: Conference Series, 2009 The most widely used method for comparing mode shapes from finite elements and experimental measurements is the Modal Assurance Criterion (MAC), which returns a single numerical value and carries no explicit information on shape features. New techniques,

Damage Detection in Steel Plates Based on Comparing Analytical Results of the Discrete 2-D Wavelet Transform of Primary and Secondary Modes Shape [PDF]
Journal of Structural and Construction Engineering, 2021 Damage occurrence is always inevitable in structures. So far, many examples of damage types in engineering structures have been recorded with many losses of human and financial. For this reason, the detecting of structural damages during its exploitation

Simplified analysis of structures using applied element method [PDF]
Songklanakarin Journal of Science and Technology (SJST), 2021 The Applied Element Method (AEM) is a numerical method of structural analysis. The degrees of freedom are located at the centroid of an element, which is rigid. In AEM, many pairs of springs are provided on the faces of the element. Although the AEM is
