Fracture Mechanics and Contact Problems in Materials Involving Graded Coatings and Interfacial Zones
Abstract
Continuously grading the thermomechanical properties of materials is becoming a powerful tool in designing new materials for specific applications. Even though the potential application of the concept is very nearly unlimited, in the near future most likely fields of application of graded materials appear to be high-temperature components, load transfer components, components with high impact resistance and improved bonding strength, and thermoelectric cells. Thus, the primary objectives of this research program have been to identify specific fracture and contact problems the solutions of which are needed in the relevant failure analysis, to develop the necessary analytical and numerical methods for solving these problems, and to provide meaningful benchmark solutions in each area identified for investigation. Particular emphasis in the program has been on the investigation of failure-oriented problems. Considering the present and future applications, the main research efforts are therefore, concentrated on fracture mechanics, contact mechanics and electrodynamics of graded materials. In this report after presenting the necessary review and background information on the application of graded materials, the objectives of the research programs and the summary of a series of benchmark solutions in the fields of fracture and contact mechanics involving graded coatings and interfaces are described.
