Dynamic programming is a method of optimization which is particularly applicable to multistage decisi n processes. And by this essential characteristic, it is also an optimization approach that transforms a complex problem into a sequence of simpler problems. In this article, we introduce the principle of optima-lity in dynamic programming and some methods for solving certain simple variable and multi-variable problems.

Fatigue crack propagation behaviour under variable amplitude loading is si- gnificantly influenced by load history induced sequence effects.In the present in- vestigation an exploratory test program with simple variable amplitude load sequ- ences was performed,which was designed to improve the general understanding of sequence effects and to offer a basis both for an evaluation of existing crack propagation prediction models and for the development of improved methods. In the first part of the study constant amplitude tests were performed over a wide range of R-ratios.The test results and the transition of the fracture mode during tests could be represented on the basis of the effective ΔK-value. In the second part of the paper tests with simple systematically varied sequ- ences of high loads,low loads and underloads were performed and the crack pro- pagation behaviour was measured.Finally,some general viewpoints regarding further developments of models are outlined.
