| 中文摘要 | The mechanical behavior of a ceramic coating and the evolution of this behavior in-service play crucial roles in governing the performance and lifetime of these materials. A protocol is presented that allows for characterization of the in-plane elastic modulus and strain to failure of fragile ceramic coatings. The protocol employs digital image correlation (DIC) to measure time-resolved, full-field strain maps of bilayer microbeams, and material properties are extracted through direct comparison with finite element simulations of microbending experiments. The efficacy of the method is demonstrated by the measurement of the in-plane Young's modulus (E(TBC) = 15-30 GPa) and the strain to fracture (3.5-5 x 10(-3)) of electron beam physical vapor deposited 7% yttria-stabilized zirconia thermal barrier coatings (TBCs). The results from this study also indicate that the in-plane TBC modulus has no strain dependence when measured in tension. (C) 2011 Published by Elsevier Ltd. on behalf of Acta Materialia Inc. |
