Book Description
Because of the need for a better understanding of the effect of Arctic low temperature environments on the mechanical behavior of high-strength low-alloy (HSLA) steels, a comparative study has been undertaken to evaluate the effect of low temperature on the mechanical properties of two candidate steels, columbium-molybdenum "acicular ferrite" HSLA steel and high-columbium HSLA steel. The paper presents the data relating to the effect of low temperature on the mechanical properties, namely, dynamic fracture toughness KId properties, through instrumented impact testing of precracked Charpy V-notch samples and cyclic properties of the two steels. It also discusses the results in terms of their significance to material specification, selection, and performance criteria for safe and economical transportation of petroleum resources from the Canadian Arctic.

Book Description
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.

Book Description
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.
