Available in PDF, EPUB and Kindle. Book excerpt: In the last few decades, much research work was conducted to improve ship structure analysis and design. Most of the efforts were directed to improve the strength of hull girder and to use the method of finite element analysis more efficiently and effectively. Because of the high degree of complexity of ship structures the interaction between hull girder strength and local strength require special attention. The complex system of stresses could produce unacceptable deformations and high values of equivalent stresses. This book covers an area of ship structure analysis and design that has not been exhaustively covered by other books on ship structures in a simple form. It presents the basic concepts of the methods and procedures required to calculate torsion and shear stresses in ship structures. Moreover, it is enhanced with a set of some solved and unsolved problems, very useful for students of naval and marine engineering.

Download or read book Torsion of Thin Walled Structures written by Krishnaiyengar Rajagopalan and published by Springer Nature. This book was released on 2022-02-03 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: This comprehensive textbook focuses on the torsion in thin walled structures, highlights the nuances of the problems faced and succinctly discusses warping, bimoment, etc. Since in several thin walled structures, torsion is the only or dominant loading, this book addresses such unique structures as well. It provides a concise explanation of the warping properties and how they are evaluated. Thin walled structures with torsion as the preponderant loading are then treated using classical and finite element methods. No prior knowledge of the finite element method is required as the method is introduced from the basics. The same problem is worked out by both approaches so that the concepts are clearly understood by the readers. The book includes pedagogical features such as end-of-chapter questions and worked out examples to augment learning and self-testing. The book will be useful for graduate courses as well as for professional development coursework for structural engineers in the aerospace, mechanical, and civil engineering domains.
Download or read book Behavior of UHPC Structural Members subjected to Pure Torsion written by Mohammed Ismail and published by kassel university press GmbH. This book was released on 2015-01-01 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ultra High Performance Concrete (UHPC) is characterized by a very high compressive strength which may reach more than 200 MPa. The behavior of this material under tension and compression actions has been established to be very brittle in nature. Discontinuous fibers (normally steel fibers) are usually added to the UHPC mix to introduce ductility. In order to investigate the beneficial effects of using fiber reinforced UHPC in structural members subjected to torsion, a series of experimental tests on 17 UHPC beams subjected to pure torsion were carried out. The test beams consisted of plain UHPC beams, UHPC beams reinforced with steel fibers only, UHPC reinforced with steel fibers and different combinations of traditional longitudinal and transverse reinforcement. The plain UHPC beams showed very brittle behavior, whereas the UHPC beams with steel fibers only showed a post cracking ductile behavior. The addition of little steel fiber volume (e.g. 0.5 %) to the plain UHPC beams enhanced the ductility. The enhancement at the ultimate capacity amounts to about 20 %. Meanwhile, the steel fibers with 0.9 % by volume showed much enhanced ductility and a maximum enhancement of the torsional carrying capacity up to 32 %. The addition of moderate steel fiber volume (e.g. 0.9 %) to one type of traditional reinforcement (either longitudinal or transverse) accomplished an effective post cracking torsional carrying mechanism. The steel fibers shows a tendency to replace the missing type of traditional reinforcement, however this should be confirmed by more tests and by using higher steel fiber volumes. A series of experimental tests on fiber reinforced UHPC prisms to investigate the post cracking shear strength and stiffness of the used UHPC mix (e.g. M3Q) was conducted. The results of these tests revealed that this fine grained UHPC mix has a weak post cracking shear behavior. The results of these tests were used later in the Finite Element (F.E) model. An analytical model based on the well known thin-walled tube analogy was developed in order to estimate the torsional carrying capacity of beams under pure torsion having different combinations of steel fibers and traditional reinforcement. The comparison between the test and model results showed very good agreement for all cases. A finite element model based on calibrated small scale tests was developed using ATENA F.E. package to predict the full load-deformation behavior of the test beams. The predictions of the model show very good agreement with the test results.

Available in PDF, EPUB and Kindle. Book excerpt: A Clinical Guide to Urologic Emergencies A Clinical Guide to Urologic Emergencies An ageing population and a predicted shortfall in the number of urologists means that, increasingly, the management of complex urological problems will fall to hospital emergency departments and the surgeries of primary care physicians. With many doctors and medical students now having less exposure to urology, there is a real and urgent need for accessible and practical guidance in managing urologic emergencies. A Clinical Guide to Urologic Emergencies offers practical guidance to the best practices in diagnosis, treatment and management of patients with urgent urological conditions. Designed to be an extremely useful tool to consult in the clinical setting, it will be a vital source of information and guidance for all clinicians, irrespective of their level of urologic knowledge. Edited by an outstanding international editor team, this book is particularly aimed at physicians, advanced practice providers, and urology and emergency medicine trainees managing patients in diverse healthcare settings across the globe. A Clinical Guide to Urologic Emergencies is accompanied by a website featuring video content at www.wiley.com/go/wessells/urologic

Available in PDF, EPUB and Kindle. Book excerpt: The differential equations and boundary conditions appropriate to the analysis of torsional vibrations of hollow thin-walled cylindrical beams are presented. General solutions for the modes and frequencies of cantilever and free-free cylindrical beams of arbitrary doubly symmetrical cross section with uniform wall thickness derived. Numerical calculations for beams of rectangular cross section are used to determine the influence on torsional vibrations of bending stresses due to torsion and a longitudinal inertia. The inclusion of longitudinal inertia exposes a strong coupling of the torsional vibration with longitudinal vibrations at low plan-form aspect ratios, and some of the frequencies obtained are seen to be actually associated with modes of primarily longitudinal vibration. The solution for cylinders of rectangular cross section is also used to investigate the the accuracy of a solution obtained from an analysis of an equivalent four-flange box beam.

Download or read book Flexural Torsional Buckling of Structures written by N. S. Trahair and published by CRC Press. This book was released on 2017-11-13 with total page 352 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flexural-Torsional Buckling of Structures provides an up-to-date, comprehensive treatment of flexural-torsional buckling and demonstrates how to design against this mode of failure. The author first explains the fundamentals of this type of buckling behavior and then summarizes results that will be of use to designers and researchers in either equation or graphical form. This approach makes the book an ideal text/reference for students in structural engineering as well as for practicing civil engineers, structural engineers, and constructional steel researchers and designers. The book begins by introducing the modern development of the theory of flexural-torsional buckling through discussions on the general concepts of equilibrium, total potential, virtual work, and buckling. It then continues with in-depth coverage of hand methods for solving buckling problems, the analysis of flexural-torsional buckling using the finite element method, and the buckling of different types of structural elements and frames composed of various elastic materials. Other topics addressed include the design and inelastic buckling of steel members. The book's final chapter considers a collection of special topics.
