Materials Data for Cyclic Loading
Materials data for cyclic loading are becoming increasingly important as a tool for materials characterization and engineering design. They can serve as the basis for a comparative judgement of a material's mechanical behaviour. Furthermore, knowledge of the stress-strain behaviour during cyclic loading is required more and more frequently in finite element calculations of cyclically loaded structural parts. Finally, such data are a fundamental input for the fatigue life estimation procedure known as the Local Strain Approach or Notch Strain Approach. Materials data for cyclic loading have been published in the scientific literature for many years, but have been collected in quite different ways. This is the first time that such data have been gathered together, evaluated according to uniform approach and methods, and compiled on standardised data sheets. The handbook comprises five volumes containing a collection of some 600 datasets with over 4000 experimental results in total.

Materials Data for Cyclic Loading, Part C: High-Alloy Steels provides the necessary data for a proper material assessment. The book presents the data of high-alloy steels that help estimate the crack initiation lives of structural parts. The data sheets included in the text provide the description of the material and testing procedures, along with diagrams for stress-strain curves for monotonic and cyclic loading strain life curve. The book also provides the results of stress- and strain-controlled constant amplitude tests. The text will be useful to researchers and practitioners of engineering, metallurgy, and physics.

Materials Data for Cyclic Loading, Part B: Low-Alloy Steels presents materials data for cyclic loading which provide the basis for materials assessment by direct comparison of data or characteristic values and for estimating the crack initiation lives of low-alloy steels under constant and variable amplitude loading. The data include stress-strain curves, strain life curves, and mean stress parameter life curves for cyclic loading. Each data sheet takes up a maximum of four pages. The first page gives a description of the material and testing procedure. The chemical composition is always given in weight percent and corresponds to the values given in the literature referred to. The second and third pages show the diagrams for: stress-strain curves for monotonic and cyclic loading; strain life curve;, and mean stress (damage) parameter life curve according to the parameter of Smith, Watson and Topper. Unless indicated otherwise in the plots, the experiments were carried out at room temperature in laboratory air. The diagrams for the stress-strain relationships contain at the most three curves, one for monotonic loading and two for cyclic loading, the latter being evaluated from incremental step tests and constant amplitude tests. All three curves can be described approximately by an analytical function. This book will be of interest to materials scientists.
