Abstract/Summary Structural Health Monitoring (SHM) is one aspect of a revolution based on the use of smart materials and structures technologies that have the potential to provide major gains in structural performance and cost-efficient life management. This paper presents a theoretical investigation using finite element analysis (FEA) of the strain response induced in SHM surface mounted transducers by a tensile loaded substrate. It examines the effect on strain transfer of 3 different transducer layups, and changes to the adhesive bond layer modulus and thickness between the host substrate and the sensor. The effects of changing the piezoceramic element diameter, piezoceramic thickness and transducer encapsulating polymer are also investigated. The results show that transducer layup can be used to reduce strain transfer to the piezoceramic element. Changing the number, modulus or thickness of the intermediate layers between the host and the element is an effective means of reducing the magnitude of strain within the piezoceramic element.
