Robert Coppolino - The Integrated Test Analysis Process for Structural Dynamic Systems
Morgan & Claypool Publishers, 2020
pdf, 166 pages, english
ISBN: 978-1-681-73681-5
Over the past 60 years, the U.S. aerospace community has developed, refined, and standardized an integrated approach to structural dynamic model verification and validation. One name for this overall approach is the Integrated Test Analysis Process (ITAP) for structural dynamic systems. ITAP consists of seven sequential tasks, namely: (1) definition of test article finite element models; (2) systematic modal test planning; (3) measured data acquisition; (4) measured data analysis; (5) experimental modal analysis; (6) systematic test-analysis correlation; and (7) reconciliation of finite element models and modal test data. Steps 1, 2, and 7 rely strictly on mathematical model disciplines, and steps 3 and 4 rely on laboratory disciplines and techniques. Current industry practice of steps 5 and 6 calls for interaction of mathematical model and laboratory disciplines, which compromises the objectivity of both modeling and laboratory disciplines. This book addresses technical content, strategies, and key relevant experiences related to all steps of ITAP, except for measured data acquisition which is the specialized domain of highly experienced laboratory professionals who contend with mechanical and electrical practicalities of instrumentation, excitation hardware, and data collection systems. |

Chuanzhi Huang - Limit Analysis Theory of the Soil Mass and Its Application
Springer, 2020
pdf, 472 pages, english
ISBN: 978-981-15-1571-2
In the geotechnical engineering, stability is a key factor of the engineering success. It is one of long-term objectives for scientists and engineers to strive for limit analysis theories and methods on and for stability of the slope, ground bearing capacity, and soil pressure. For the port construction, it is developing toward the large-size and deep water areas. As the natural environment conditions, including ground, are relatively poor, it puts forward higher requirements for analysis and calculation theory on geotechnical engineering. The author and his colleagues work together to, based on the former work, make some progress by original study methods. Hereby, the study achievements are collated into a book, which is of great significance.
Main features of the book are described as follows: It provides the extremum condition of the yield function and regards it as one of fundamental equations so that one set of complete fundamental equations are available for the limit analysis, and it constitutes a complete limit equilibrium or variation issue. On this basis, a brand-new solution method—generalized limit equilibrium method—is provided, which can be mutually corroborated with limit equilibrium method, slip line method, and upper- and lower-bound plasticity analysis method. During the study on slope stability, it avoids such study model as solving the statically indeterminate problem by introducing assumptions, which is commonly applied in the classical methods; the proposed slope stability analysis method is more consummate, and the calculation results are more reliable. In the study on the ground bearing capacity, it solves not only the calculation problem on the ground bearing capacity of heterogeneous soil, but also the application scopes of calculation methods are more extensive. Therefore, all above are innovative achievements, and its brand-new limit equilibrium analysis theory is more scientific compared with the former work.
Another feature of the book is the close combination of the study and engineering practices, together with the stress on practical problems in the engineering. For example, the calculation method for the ground bearing capacity is established in consideration of port engineering features; for tens of engineering examples, different calculation methods are applied for the calculation and analysis, and it has verified that the proposed method is of extensive application prospects. |

Raphael Boulbes - Troubleshooting Finite-Element Modeling with Abaqus
With Application in Structural Engineering Analysis
Springer, 2020
pdf, 453 pages, english
ISBN: 978-3-030-26740-7
This book gives Abaqus users who make use of finite-element models in academic or practitioner-based research the in-depth program knowledge that allows them to debug a structural analysis model. The book provides many methods and guidelines for different analysis types and modes, that will help readers to solve problems that can arise with Abaqus if a structural model fails to converge to a solution. The use of Abaqus affords a general checklist approach to debugging analysis models, which can also be applied to structural analysis.
The author uses step-by-step methods and detailed explanations of special features in order to identify the solutions to a variety of problems with finite-element models. The book promotes:
- a diagnostic mode of thinking concerning error messages;
- better material definition and the writing of user material subroutines;
- work with the Abaqus mesher and best practice in doing so;
- the writing of user element subroutines and contact features with convergence issues; and
- consideration of hardware and software issues and a Windows HPC cluster solution.
The methods and information provided facilitate job diagnostics and help to obtain converged solutions for finite-element models regarding structural component assemblies in static or dynamic analysis. The troubleshooting advice ensures that these solutions are both high-quality and cost-effective according to practical experience.
The book offers an in-depth guide for students learning about Abaqus, as each problem and solution are complemented by examples and straightforward explanations. It is also useful for academics and structural engineers wishing to debug Abaqus models on the basis of error and warning messages that arise during finite-element modelling processing. |

Paul Chess, Warren Green - Durability of Reinforced Concrete Structures
CRC Press, 2020
pdf, 149 pages, english
ISBN-13: 978-0-367-27838-0
Reinforced concrete structures corrode as they age, with significant financial implications, but it is not immediately clear why some are more durable than others. This book looks at the mechanisms for corrosion and how corrosion engineering can be used for these problems to be minimized in future projects. Several different examples of reinforced concrete structures with corrosion problems are described and the various life enhancement solutions considered and applied are discussed. The book includes a chapter on the effectiveness of corrosion monitoring techniques and questions why the reality is at odds with current theory and standards.
Specialist contractors, consultants and owners of corrosion damaged structures will find this an extremely useful resource. It will also be a valuable reference for students at postgraduate level. |
