Book excerpt: Ceramic thermal barrier coatings (TBC) on internally cooled metallic turbine blades give a potential for increasing the turbine gas inlet temperatures in a range of 50-150°C. Since, at higher gas inlet temperatures the remaining lifetime of the blade after failure of the TBC is extremely short, reliable lifetime prognosis for TBCs in service is required. A lifetime assessment concept is presented which is based on realistic thermal and mechanical fatigue (TMF) testing. To achieve short testing times with the TMF test rig kinetic damages, depending on the time at high temperature, are imposed separately so that a TMF cycle lasts about 1% of real service cycles. Substrate materials failed in TMF tests due to fatigue cracks. The fatigue load entailing failure of the substrate at the proposed design life determines the maximal cyclic strain of the ceramic TBC and was therefore chosen for TMF tests on TBC-coated specimens. TBCs in 'as coated' condition survived the required load alternations without any cracks, which implies that the premature failure of TBCs in service is due to interacting kinetic damage mechanisms.

Book excerpt: This volume contains 50 contributions presented at the symposium `Fatigue under Thermal and Mechanical Loading'. The symposium addressed the mechanisms, mechanics and modelling of thermal and thermal-mechanical load effects on conventional and advanced structural materials. The proceedings provide an update of the research efforts in thermal and thermal-mechanical fatigue. The papers cover a wide range of materials, including metallic alloys from steels to advanced superalloy single crystals, ceramics as well as composites. Topics encompass recent developments in specimen and component testing techniques, mechanisms and mechanics of inelastic deformation, crack initiation and crack growth, as well as damage modelling for life-time prediction. The book is of interest to materials scientists, mechanical engineers and design engineers involved in the design of components for use at high temperatures.

Available in PDF, EPUB and Kindle. Book excerpt: A life prediction model that determines the contribution of fatigue, creep and environmental damage to failure was developed for an aluminide coated nickel-based superalloy, Mar-M247. In the first phase of the study, isothermal (IF) and thermomechanical fatigue (TMF) experiments were conducted to investigate the experimental damage mechanisms. In the second phase, an analytical technique was advanced to compute the stress fields due to a surface inclusion in a half-space where the inclusion simulates the oxide spike. The technique is based on Eshelby's equivalent inclusion method and elucidates the mismatch in elastic moduli and thermal expansion coefficients of the matrix and the oxide spike on local strain fields. The fatigue life results of several experiments, along with the local stress-strain field in the vicinity of an oxide spike, were employed to define the model constants. Life prediction bounds are established corresponding to short-time coating protection, where the coating provides inconsiderable protection to substrate, and long-time coating protection, where the coating provides appreciable protection to the substrate. For in-phase loading, since the failure is governed by creep damage, the nature of coating protection did not influence the fatigue lives. The out-of-phase predictions corresponding to short-time coating protection and the experimental data coincided as the maximum temperature increased in the experiments, confirming that the coating provides unsubstantial protection at higher temperatures.

Available in PDF, EPUB and Kindle. Book excerpt: The aim of this major reference work is to provide a first point of entry to the literature for the researchers in any field relating to structural integrity in the form of a definitive research/reference tool which links the various sub-disciplines that comprise the whole of structural integrity. Special emphasis will be given to the interaction between mechanics and materials and structural integrity applications. Because of the interdisciplinary and applied nature of the work, it will be of interest to mechanical engineers and materials scientists from both academic and industrial backgrounds including bioengineering, interface engineering and nanotechnology. The scope of this work encompasses, but is not restricted to: fracture mechanics, fatigue, creep, materials, dynamics, environmental degradation, numerical methods, failure mechanisms and damage mechanics, interfacial fracture and nano-technology, structural analysis, surface behaviour and heart valves. The structures under consideration include: pressure vessels and piping, off-shore structures, gas installations and pipelines, chemical plants, aircraft, railways, bridges, plates and shells, electronic circuits, interfaces, nanotechnology, artificial organs, biomaterial prostheses, cast structures, mining... and more. Case studies will form an integral part of the work.
