Abstract
The objective of this chapter is to impart a better understanding of the mutual dependence of theory and experiment in fracture mechanics. An experiment cannot be considered successful unless the results are interpreted within the framework of some preconceived concept and/or theoretical prediction. Otherwise the test results are of no more value than to predict the results of other tests conducted under exactly the same conditions. Interpreting experimental results requires a sound knowledge of the fracture process and governing physical principles. In addition, theoretical speculations on these processes must be guided by experimental observations. The interplay between theory and experiment is essential to the development of both theories and experiments.
