... Interpolation Frequencies Vibration measurement Stress (materials) The thickness of the plate is represented by h, B are the strain‐displacement matrices and c are the material matrices (Dinis et al., 2007a , b), (Equation 10) In the meshless methods (Belytschko et al...

... has been developed and dynamic parameters are calculated. In the second stage, change in the dynamic properties of farmed reinforced concrete building model is identified from vibration measurements under different level of controlled damage. In the third stage, search for the damaged stories...

... frequency difference method to determinate cable tensions is demonstrated by the laboratory tests and field ambient vibration measurements of stay cables. For a horizontal cable subjected to a small perturbation around the static equilibrium position as shown in Figure 1 , the equations of motion...

... both safely and economically. Originality/value The tool developed is quite general and is believed to be applicable to many types of structural optimisation analyses. Optimization techniques Earthquakes Vibration measurement Damping Structural damping depends on many factors...

... Design management Vibration measurement System monitoring Impact strength Forging hammers are efficient and widely used machines in metal forming and manufacturing industry. Although the equipment has been improved in many ways, the same working principle and many inherent drawbacks remain...

...Henning Ressing; Mohamed S. Gadala Purpose To investigate the feasibility of using single/multi variable optimisation techniques with vibration measurements in solving the inverse crack identification problem. Design/methodology/approach The finite element method is used to solve the forward...
