...Yang Zhang; Joshua Dupont; Ting Wang; Jiong Tang The piezoelectric impedance-based technique is increasingly recognized for its promise in structural health monitoring and damage identification. Built upon their self-sensing actuation capability, piezoelectric transducers can be integrated...

... Liao. 14 09 2011 26 06 2012 An impedance-based approach for analyzing an axial rod with shear-type damping layer treatment is proposed. The rod and shear-type damping layer are regarded as two subsystems and both impedances are calculated analytically. The system impedance can...

... amount of block masses. Each block mass behaves as an elastic structure member, and its thickness can be determined systematically using the impedance technique proposed in this paper. A design is given to demonstrate the methodology, and the result is experimentally validated. 01 09 2004 11 11...

..., the natural frequencies of a structure are changed to designated values using structural patches. The structural patch is deformable so it is different from a concentrated mass. The required thickness and location of the structural patch are determined analytically using impedance techniques in the proposed...
