This book describes a slamming strength assessment procedure for vessels. Typically, there are three types of slamming loads on commercial vessels: bottom slamming, bow flare slamming, and stern slamming depending upon the hull geometry at the bow and stern. Upon verifying compliance with the requirements in this book, optional notations may be assigned to the vessel. A fundamental requirement of Class is that the scantlings of the hull structure are to be in accordance with the criteria as specified by Class. The results of this book are therefore not to be used to reduce the basic scantlings obtained from the application of the Class rules. That is, if the results from this book indicate the need to increase any basic scantlings, the increased scantlings are to be implemented above the Class Rule requirements.

​Like many sectors, agriculture is experiencing a continuous digitalization, i.e. an increase in data-driven technologies used. In contrast to companies of other critical infrastructures, a typical farm is comparatively small and often runs as a family business. Accordingly, the demands on farming technology, its implementation, and regulations are different in many terms. Currently, a promising technological trend of agriculture is smart farming, that incorporates more precise cultivation with less manual effort. But such new developments usually lack an assessment about its impact on the sector's resilience and dependencies on other infrastructures. It remains unclear, how digitalization impacts the resilience of food production and food safety. Therefore, it is not well researched which technological developments may lead to undesired effects in the future. How modern systems should be designed to allow for both, positive impacts on efficiency, and prevention of negative effects interms of reduced resilience capacities, is also not answered by current literature. The aim of the work is to close this research gap in the interplay between agriculture, digitalization, and resilience.

The book focuses primarily on experimental and analytical methods developed over many years to characterize the deformation and fracture of brittle materials under dynamic loading conditions. The dynamic response of brittle materials is highly nonlinear and complex, with practical applications ranging from explosive excavation of rocks to the design of ceramic armor and the protection of spacecraft windows from meteor impacts. It provides a comprehensive exploration of the challenges and methodologies involved in impact experiments and computational modeling of brittle solids under shock and impact loading, making it essential reading for those seeking realistic solutions to blast and ballistic problems. For example, the book emphasizes the significance of validating numerical code solutions through simulations. This involves understanding and evaluating the impact of various factors such as appropriate boundary conditions, high-resolution finite element meshes, solution time steps, contact algorithms, interface modeling, artificial viscosity, erosion of elements, particle conversion, and model parameters on the accuracy of solutions. It selectively presents examples of modeling and simulations of ballistic problems drawn from the open literature. While numerous articles on the book's topic exist in the literature, this volume integrates key aspects of high strain rate impact experiments, modeling, and simulations of brittle failure in ceramics, rocks, oil shale, and cementitious materials across various stress and strain states. To the best of the authors'knowledge, no other compilation covers such a wide array of experimental techniques used in this field, particularly for ceramics, yet adaptable for other heterogeneous brittle solids. Despite the extensive literature on this subject, most impact experimental configurations have been limited to specific geometries and have not encompassed the broad range of techniques necessary to characterize and validate constitutive behaviors used in modern numerical codes. Many researchers and engineers are often unaware of the specialized experiments and models presented in international conference proceedings or technical presentations. This book addresses that gap by encompassing a broader range of unique impact experiments, constitutive and damage modeling, and computational simulations not found in any existing publication.

This book presents comprehensive experimental, numerical, and theoretical studies on the highway bridge under collision and explosion. Highway bridge is one of the significant civil infrastructures of public transportation, which plays an important role in the sustained and stable growth of the national economy. However, with the development of the transportation industry and bridge construction, the risks of accidental vehicle- and vessel-bridge collisions, as well as the explosion during the whole service life of the bridge are also increasing. Therefore, the damage assessment and protective design of the highway bridge have become the concerned topic in the field of bridge engineering in recent years. The book is intended for researchers and graduate students majoring in bridge engineering and protective engineering, as well as professional engineers working in the field of bridge design.

Working and living onboard vessels imposes a series of generally low-frequency mechanical vibrations as well as single-impulse shock loads on the human body. Also, exposure to noise is characteristic aboard vessels. Low-frequency vibrations are created by vessel motions, which are produced by the various sea states in conjunction with vessel speed and point of sail. These motions can result in motion sickness, body instability, interruptions of task performance, sleep interruption and fatigue, increased health risk aggravated by shock loads due to slam and reduced human efficiency. Higher-frequency vibration influences comfort and is often associated with rotating machinery. The imposition of higher frequency vibrations (about 1 to 80 Hz) induces corresponding motions and forces within the human body creating discomfort and reduced human efficiency. With regard to noise, the above can similarly affect exposed humans, notably with sleep interruption and resulting fatigue, discomfort, and reduced efficiency. Also of concern are transient and permanent hearing loss, masking of audible signals, and interruption of speech communication. The concerns related to levels and characteristics of noise and vibration are covered in this and the other titles in the series related to ship vibration and noise control. be granted any of the associated habitability notations, specific noise and vibration criteria must be met. Ship designers in pursuit of these notations often request guidance on how to control levels of noise and vibration in inhabited spaces. As a result, this book has been written. The information presented in this book is intended for guidance only to support vessel designers and operators in controlling vessel noise and vibration in the general case, and more specifically in meeting the requirements of classification society habitability rules.

Ceramic-matrix composites (CMCs) possess high specific strength and modulus at elevated temperature, and have already been applied in hot-section components in aero-engines. To ensure the operation reliability and safety of CMCs components, it is necessary to understand the micro damage mechanisms and internal damage state in the composites. This book focuses on the micromechanics of CMCs at elevated temperatures, including, the stress-strain behavior, proportional limit stress, residual strength, mechanical hysteresis, interface damage, strain response, and lifetime of CMCs at elevated temperatures. This book can help the material scientists and engineering designers to better understand and master the micromechanics of CMCs at elevated temperatures.
