THE DESIGN AND ANALYSIS OF EXPERIMENTS. By Oscar Kempthorne. New York, John Wiley and Sons, Inc., 1952. 631 pp. $8.50. This book by a teacher of statistics (as well as a consultant for \"experimenters\") is a comprehensive study of the philosophical background for the statistical design of experiment. It is necessary to have some facility with algebraic notation and manipulation to be able to use the volume intelligently. The problems are presented from the theoretical point of view, without such practical examples as would be helpful for those not acquainted with mathematics. The mathematical justification for the techniques is given. As a somewhat advanced treatment of the design and analysis of experiments, this volume will be interesting and helpful for many who approach statistics theoretically as well as practically. With emphasis on the \"why,\" and with description given broadly, the author relates the subject matter to the general theory of statistics and to the general problem of experimental inference.

The Design and Analysis of Experiments

3D printing, more formally known as Additive Manufacturing (AM), is already being adopted for rapid prototyping and soon rapid manufacturing. This review provides a brief discussion about AM and also the most employed AM technologies for polymers. The commonly-used ASTM and ISO mechanical test standards which have been used by various research groups to test the strength of the 3D-printed parts have been reported. Also, a summary of an exhaustive amount of literature regarding the mechanical properties of 3D-printed parts is included, specifically, properties under different loading types such as tensile, bending, compressive, fatigue, impact and others. Properties at low temperatures have also been discussed. Further, the effects of fillers as well as post-processing on the mechanical properties have also been discussed. Lastly, several important questions to consider in the standardization of mechanical test methods have been raised.

Guide to stability design criteria for metal structures

In conjunction with load and resistance factor design specifications, advanced methods of inelastic analysis afford the opportunity to design steel structures based on realistic assessments of limit state behavior. This paper presents a summary of a study of the in‐plane behavior of a series of low‐rise frames. Designs are obtained that rely on a second‐order inelastic analysis to demonstrate that the frame and its members are adequate in resisting the effects of factored loads. The inelastic designs are compared with designs obtained using conventional elastic methods of design. A representative inelastic design is further evaluated with respect to strength and serviceability limit state behavior, including conformance with current load and resistance factor design specification provisions. The accuracy and reliability of using a second‐order concentrated plasticity analysis to model system behavior are also established. The investigation indicates that second‐order inelastic analysis can be used effecti...

Characterization of stiffness degradation caused by fatigue damage of additive manufactured parts

A fundamental aim of developing and applying nonlinear analysis is to improve the quality of design by providing the engineer with a more reliable prediction of the performance of a structural system that is under design or investigation. This paper describes a modification to the second-order inelastic hinge method that can produce the accuracy of more sophisticated plastic zone methods in the analysis of in-plane behavior of compact doubly symmetric sections. As a basis for comparison, results are provided for an established set of benchmark problems.
