Fiber reinforced polymer composites are an extremely broad and versatile class of material.Their high strength coupled with lightweight leads to their use wherever structural efficiency is at a premium. Applications can be found in aircraft, process plants, sporting goods and military equipment.
However they are heterogeneous in construction and antisotropic, which makes making strength prediction extremely difficult especially compared to that of a metal.
This book brings together the results of a 12year worldwide failure exercise encompassing 19 theories in a single volume. Each contributor describes their own theory and employs it to solve 14 challenging problems. The accuracy of predictions and the performance of the theories are assessed and recommendations made on the uses of the theories in engineering design.
All the necessary information is provided for the methodology to be readily employed for validating and benchmarking new theories as they emerge.
Brings together 19 failure theories, with many application examples.
Compares the leading failure theories with one another and with experimental data
Failure to apply these theories could result in potentially unsafe designs or over design.

Introduction and scope -
The Shore Approach structure is a landfall for gas pipelines on the exposed western coast of Norway. The pipelines are placed inside a submerged concrete tunnel which acts as an underwater protecting bridge over the rocky sea bed. The tunnel elements were produced and installed during summer and fall 1982.
Due to a very tight construction schedule, no time was left for mix design tests, and a concrete quality with ample margin for strength requirements was chosen. The structure is exposed to very severe environment, both from a statically and durability point of view.
Durability performance for the structure was much higher than normal at that time, and very close to the specifications in Norwegian Standards today for the same exposure conditions (exposure class XS3). The structure has therefore been continuously inspected up to 26 years in service.
The scope of the inspection is partly to document the condition of the structure and especially to evaluate the requirements for concrete mix design and concrete cover in current concrete standards in Norway for structures in exposure class XS3.

A thorough introduction to the fundamentals of probability theory
This book offers a detailed explanation of the basic models and mathematical principles used in applying probability theory to practical problems. It gives the reader a solid foundation for formulating and solving many kinds of probability problems for deriving additional results that may be needed in order to address more challenging questions, as well as for proceeding with the study of a wide variety of more advanced topics.
Great care is devoted to a clear and detailed development of the conceptual model' which serves as the bridge between any real-world situation and its analysis by means of the mathematics of probability. Throughout the book, this conceptual model is not lost sight of. Random variables in one and several dimensions are treated in detail, including singular random variables, transformations, characteristic functions, and sequences. Also included are special topics not covered in many probability texts, such as fuzziness, entropy, spherically symmetric random variables, and copulas.
Some special features of the book are:
- a unique step-by-step presentation organized into 86 topical Sections, which are grouped into six Parts
- over 200 diagrams augment and illustrate the text, which help speed the reader's comprehension of the material
- short answer review questions following each Section, with an answer table provided, strengthen the reader's detailed grasp of the material contained in the Section
- problems associated with each Section provide practice in applying the principles discussed, and in some cases extend the scope of that material
- an online separate solutions manual is available for course tutors.
The various features of this textbook make it possible for engineering students to become well versed in the machinery' of probability theory. They also make the book a useful resource for self-study by practicing engineers and researchers who need a more thorough grasp of particular topics.
