The analytic model extends the Suquet[29] estimates method to the piezoelectric domain where acomplete set of electromechanical constants are obtained for threepiezoelectric ceramics belonging to different symmetry classes.Specific results are generated for the cases of a square arrangementof cylindrical pores, where the alignment of the pores is in thedirection of poling of the matrix phase and a cubic arrangement ofspherical pores. The trends obtained from the analytic model arecompared with the finite-element model and found to be in goodagreement for all components of effective piezoelectric constants uptolarge volume fractions. A three-dimensional finite element model isdeveloped in part II of the thesis to completelycharacterize the behaviour of a general porous piezoelectric compositewith pores of 0-3 type flat cuboidal, 0-3 type cylindrical, 0-3 typespherical, and 1-3 type cylindrical connectivities. By consideringmaterials from different symmetry classes, it is demonstrated thatpiezoelectric composites designed with 0-3 type flat cuboidal poresare more suitable for hydrophone applications by identifying thevariation in piezoelectric strain coefficient and the hydrostaticfigure of merit with varying porosity volume fraction."},{"label":"dcterms.available","value":"2012-05-15T18:04:10Z"},{"label":"dcterms.contributor","value":"Robert Kukta."},{"label":"dcterms.creator","value":"Iyer, Sumantu"},{"label":"dcterms.dateAccepted","value":"2015-04-24T14:52:35Z"},{"label":"dcterms.dateSubmitted","value":"2012-05-15T18:04:10Z"},{"label":"dcterms.description","value":"Department of Mechanical Engineering"},{"label":"dcterms.format","value":"Monograph"},{"label":"dcterms.identifier","value":"http://hdl.handle.net/1951/55478"},{"label":"dcterms.issued","value":"2010-12-01"},{"label":"dcterms.language","value":"en_US"},{"label":"dcterms.provenance","value":"Made available in DSpace on 2015-04-24T14:52:35Z (GMT).
