Summary on Grant Application Form |
|
The main motivation of this project is the development of advanced ceramic materials and their increasing usage in load bearing applications at temperatures where time-dependant deformation determines the operational lifetime. The principal advantage of using indentation creep as a test method are: (1) the high hydrostatic stress beneath the indenter inhibits fracture and thus allows the mechanics and mechanisms of the deformation process to be investigated, (2) the applied stress state is similar to that developed in many practical applications, (3) the ease and hence low cost, of specimen preparation, (4) the relative rapidity and low cost of the test method and (5) the small volumes of material required.This study will investigate the influence of experimental variable; i.e. load, indenter geometry and hardness, heating of indenter, friction coefficient and variable loading on the measured deformations. The engineering ceramics to be studied will include magnesium oxide, silicon carbide and zirconia. The Li, Henshall, Hooper and Easterling model of indentation creep will be used to interpret the measured data.
