This volume is the first to give the mathematical background and a comprehensive survey of the old and new summation formulae resulting in an approximate value of the critical load factor of a complex problem by means of the critical load factors of subproblems by addition. The theorems and formulae are richly illustrated by examples in structural engineering.

Stability of Discrete Non-conservative Systems first exposes the general concepts and results concerning stability issues. It then presents an approach of stability that is different from Lyapunov which leads to the second order work criterion. Thanks to the new concept of Kinematic Structural Stability, a complete equivalence between two approaches of stability is obtained for a divergent type of stability. Extensions to flutter instability, to continuous systems, and to the dual questions concerning the measure of non-conservativeness provides a full, fresh look at these fundamental questions. A special chapter is devoted to applications for granular systems. Presents a structured review on stability questions Provides analytical methods and key concepts that may be used in non-conservative frameworks like hypoelasticity

Structural Stability in Engineering Practice elucidates the various problems associated with attaining stability, and provides the results for practical use by the design engineer. By presenting a simple and visual description of the physical phenomena, the authors show how to determine the critical loads of various structures, such as frames, arches, building structures, trusses and sandwiches. Special emphasis is given to the post-critical behaviour - essential for assessing the safety of structures - and furthermore to the summation theories that make the solution of complicated stability problems relatively simple.

This book presents the general reports and the presentations of the International Colloquium on Stability and Ductility of Steel Structures, held in Budapest in 2002, and dedicated to the late Professor Otto Halasz. One hundred papers have been contributed by European, American, Japanese and Australian engineers and researchers concerned with a wide range of applications of stability and ductility problems. The aim of the colloquium was to bring together specialists in the stability and ductility of steel structures, as well as to provide a forum for the exchange of information regarding the theoretical foundations and experimental investigations and methods, and to promote further development. Highlights of the volume include: design theories and the present phase of creating new standards and codes; theoretical and experimental problems of buckling of columns, lateral buckling of beams, and lateral-torsional buckling of beam-columns; the stability of steel frames and the effects of s

The present volume is the second of two parts which constitute the proceedings of the 1986 Advanced Course on Petri Nets in Bad Honnef. It discusses tools supporting the design of petri nets as well as their modification and analysis, presents a variety of applications, and covers the relationship of petri nets to other concurrency models. These current issues of the "Advances in Petri Nets" present the most significant recent results in the application and theory of petri nets to the broad computer science community. They particularly address those who are: - interested in systems design and would like to learn to use petri nets, - familiar with subareas of the theory or the applications of nets and wish to become acquainted with the whole area, - interested in learning about recent results presented within a unified framework, - going to learn about successfully applying petri nets in - various practical situations, - interested in the relationship of petri nets to other models of concurrent systems.
