Описание: This book presents a novel approach to the classical scientific discipline of Structural Engineering, which is inspired by numerous current applications from domains of Civil, Mechanical or Aerospace Engineering. The main goal of this book is to help with making the best choice between accuracy and efficiency, when it comes to building the most suitable structural models by practising engineers using modern computational tools available in commercial software products (SAP, FEAP, ANSYS ...) for which we have carried out many developments that have been become the main reference in the field. Any development of this kind is not a mere modification of discrete approximation, but a thorough treatment with a sound theoretical formulation based upon Hu-Washizu variational principle with independent rotation field, its corresponding regularization and finally the most appropriate finite element interpolation that can match those used for structural elements.
Proposed approach allows us to provide a unified discrete approximation of complex structural assemblies and greatly simplify the modeling task for structural engineers. Thus, in conclusion, this book can also be perceived as the theoretical manual for using modern computer models successfully by practising engineers.

Описание: Provides a detailed overview of the issues associated with the instability of steel structures. The book focuses on the various forms of instability associated with compressive forces, bending, shear, and torsion, including global and local buckling.
Specificity of Deformation and Strength Behavior of Massive Elements of Concrete Structures in a Medium with Low Humidity discusses the influence of weather conditions, the density of the structure, and how these elements, along with others, affect the concrete curing process. It explores the effects of climate in all phases of construction, its impact on the rheological properties of concretes, and the carrying capacity of compressed concrete and reinforced concrete elements. In addition, it provides the methods to determine the basic heterogeneity of mechanical properties of concrete structures and novel calculation methods for concrete columns and reinforced concrete beams.
Описание: Provides comprehensive coverage of indeterminate structures. This book presents individual theories followed by solved problems pertaining to that theory. The aim is to provide a clearer understanding of the subject to students. If a problem can be solved by several methods, each method is discussed.

Описание: Multiscale Structural Topology Optimization discusses the development of a multiscale design framework for topology optimization of multiscale nonlinear structures. With the intention to alleviate the heavy computational burden of the design framework, the authors present a POD-based adaptive surrogate model for the RVE solutions at the microscopic scale and make a step further towards the design of multiscale elastoviscoplastic structures. . Various optimization methods for structural size, shape, and topology designs have been developed and widely employed in engineering applications. Topology optimization has been recognized as one of the most effective tools for least weight and performance design, especially in aeronautics and aerospace engineering. . This book focuses on the simultaneous design of both macroscopic structure and microscopic materials. In this model, the material microstructures are optimized in response to the macroscopic solution, which results in the nonlinearity of the equilibrium problem of the interface of the two scales. The authors include a reduce database model from a set of numerical experiments in the space of effective strain.

Описание: My experience as a State Correction Officer inside New Yorks Prisons. As you read Paul Harringtons day-to-day and month-to-month experiences within the states prison system, you will see a broken system one that is full of loopholes, lies, cover-ups and corruption. This system is full of daily violence and numerous officers are injured by violent inmates. Each officer has their unique view of the prison system. Here, Harrington wishes to share his perspective of how different administrations created changes in the daily operations at Fishkill Correctional Facility, where he was stationed after a 15-month stint at Sing Sing. Not every day was
