Materials Data for Cyclic Loading, Part A: Unalloyed Steels provides information that aids in the comparative judgment of a material''s mechanical behavior, particularly unalloyed steels. The book contains 600 datasets and over 4000 experimental results. The data presented in the text include chemical positions, monotonic properties, cyclic properties, and failure criterion. 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.

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 D: Aluminium and Titanium Alloys 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 aluminum and titanium alloys 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.
