This book was released on 1975 with total page 41 pages. Available in PDF, EPUB and Kindle. Book excerpt: A nonlinear theory of large rotationally-symmetric plastic deformation of a sandwich-toroidal shell has been formulated. The generating curve for the toroid is assumed to be open and of an arbitrary shape. Deformation of the shell, described by the linear Cauchy's measure, is governed by the Love-Kirchhoff hypothesis. On the basis of the principle of virtual work non-linear equations of equilibrium have been derived. The material of the sandwich sheets is assumed to be rigid/perfectly-plastic and to obey the Levy-Mises theory of plastic flow and Huber-Mises-Hencky yield condition. The fundamental equations have been reduced to a system of six, coupled, ordinary, nonlinear differential equations which are, however, linear with respect to the first derivatives of unknown functions. By the use of a numerical procedure the initial/boundary problem can be reduced to a boundary value problem only, for each step of the loading process. Different types of boundary problems as well as continuity requirements have been discussed. (Author).

Download or read book The Theory of Rotationally Symmetric Plastic Shells written by Philip Gibson Hodge and published by . This book was released on 1963 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: The defining equations for a rigid/perfectly plastic shell are derived from basic principles. On the basis of a single geometric assumption for the velocity field, generalized strain rates and stresses are defined and equilibrium relations deduced. Shell yield conditions and flow law are discussed in general terms and then specifically for piecewise linear yield conditions. Preceding the general shell problem, the theory of beams under bending and axial forces is discussed to give a general insight into plastic structural behavior. The paper closes with an application to cylindrical shells and a discussion of areas for future development.
Download or read book Compensation Systems for Low Temperature Applications written by Balzej T. Skoczen and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 303 pages. Available in PDF, EPUB and Kindle. Book excerpt: The present monograph is mainly focused on the behaviour of ductile ma terials at cryogenic temperatures, stability issues concerning application of corrugated shells at cryogenic conditions and reliability oriented parametric optimisation of compensation systems containing the corrugated bellows. As there are relatively few publications on combined material and structural be haviour at very low temperatures, the monograph aims at filling this gap. It is worth pointing out that within the class of publications dedicated to low temperature behaviour of materials and structures the majority is based on testing down to the temperature of liquid nitrogen (77 K). Rare publications deal with the analysis of material and structural response at the temperature of liquid helium (4. 5 K) or superfluid helium (below the point T>. , = 2. 17 K). This can be explained by the fact that an (by its nature complex) installation for testing at such low temperatures is very expensive. Only the large research centres and universities, working in the domain of superconductivity, cryogen ics or developing superconducting magnets for particle accelerators, can afford such installations. A significant part of the present monograph is dedicated to the analy sis of the phenomena associated with plastic yielding in stainless steels at cryogenic temperatures. Generally, three phenomena are distinguished: plas tic strain induced phase transformations, serrated yielding and evolution of ductile damage.

Available in PDF, EPUB and Kindle. Book excerpt: This book attempts to bring the essence of shell structures within the grasp of engineers. It tackles the fundamental question of how bending and stretching effects combine and interact in shell structures from a physical point of view; and shows that this approach leads to an understanding of the structural mechanics of shells in general.

This book was released on 2012-12-06 with total page 501 pages. Available in PDF, EPUB and Kindle. Book excerpt: This collection of papers is a state of the art presentation of theories and methods related to the problem of the behaviour of mechanical structures under variable loads beyond their elastic limit In particular, the problems of shakedown, ratchetting, transient and asymptotic cyclic states are addressed. The volume is composed of four chapters devoted to material modelling for cyclic loading conditions; general theory of accommodated states of structures; effects of changes of the geometry on the inelastic structural response; and numerical techniques with applications to particular engineering problems. It was aimed to provide a unified approach in order to understand both inelastic material and structural response under variable loading conditions. The attempt to extend the classical shakedown theory of Melan and Koiter to geometrically non-linear problems is presented in several papers. The industrial application of cyclic plasticity to the analysis and the design of pressure bellows, compensators, turbine disks, or flange connections under thermal and pressure cycles illustrates the great potential of the numerical techniques developed for this purpose using mostly min-max approaches. The treatment of railway problems and the analysis and optimisation of pavements are further examples of important areas of applications. Emphasis was laid on approaches that take into account the fact that loading histories are often not precisely known Therefore, the center of interest lies in other than step by step calculation methods.

Available in PDF, EPUB and Kindle. Book excerpt: Structural Impact is concerned with the behaviour of structures and components subjected to large dynamic, impact and explosive loads which produce inelastic deformations. It is of interest for safety calculations, hazard assessments and energy absorbing systems throughout industry. The first five chapters introduce the rigid plastic methods of analysis for the static behaviour and the dynamic response of beams, plates and shells. The influence of transverse shear, rotatory inertia, finite displacements and dynamic material properties are introduced and studied in some detail. Dynamic progressive buckling, which develops in several energy absorbing systems, and the phenomenon of dynamic plastic buckling are introduced. Scaling laws are discussed which are important for relating the response of small-scale experimental tests to the dynamic behaviour of full-scale prototypes. This text is invaluable to undergraduates, graduates and professionals learning about the behaviour of structures subjected to large impact, dynamic and blast loadings producing an inelastic response.
