The book describes behavior of materials (ductile, brittle and composites) under impact loadings and high strain rates. The three aspects: experimental, theoretical and numerical are in the focus of interest. Hopkinson bars are mainly used as experimental devices to describe dynamic behavior of materials. The precise description of experimental techniques and interpretation of wave interaction are carefully discussed. Theoretical background refers to rate dependent thermo viscoplastic formulation. This includes the discussion of well posedness of initial boundary value problems and the solution of the system of governing equations using numerical methods. Explicit time integration is used in computations to solve dynamic problems. In addition, many applications in aeronautic and automotive industries are exposed.
Including the latest developments in design, optimisation, manufacturing and experimentation, this text presents a wide range of topics relating to advanced types of structures, particularly those based on new concepts and new types of materials.
The book focuses on the impact response of lightweight sandwich structures. As a kind of lightweight structure, sandwich structure has been widely used in various engineering fields, such as aerospace, ships, vehicles and so on, because of its high specific stiffness, high specific strength and versatility. During service, the sandwich structures may be subjected to various impact loads, which may result in serious damage, thereby reducing the stiffness, strength and load-bearing ca-pacity, thereby shortening the service life and bringing safety hazards. Therefore, an in-depth understanding of impact behavior and failure mechanisms is of great significance for the wider application of sandwich structures. In the past decades, many scholars have conducted in-depth research on related topics. But it is difficult for readers to systematically read all the literature in a short time. This book seeks to succinctly summarize the development and the results achieved in this field. This book focuses on simple, classical structures, such as beams, plates, and shells, under loads such as low-velocity impact, explosive load, and bullet penetrations. The main research methods are theoretical analysis, numerical simulation and experimental investigation. The purpose is to reveal the deep mechanism and lay a foundation for the application of sandwich structure in engineering practice.
Dynamic Failure of Materials and Structures discusses the topic of dynamic loadings and their effect on material and structural failure. Since dynamic loading problems are very difficult as compared to their static counterpart, very little information is currently available about dynamic behavior of materials and structures. Topics covered include the response of both metallic as well as polymeric composite materials to blast loading and shock loadings, impact loadings and failure of novel materials under more controlled dynamic loads. These include response of soft materials that are important in practical use but have very limited information available on their dynamic response. Dynamic fragmentation, which has re-emerged in recent years has also been included. Both experimental as well as numerical aspects of material and structural response to dynamic loads are discussed. Written by several key experts in the field, Dynamic Failure of Materials and Structures will appeal to graduate students and researchers studying dynamic loadings within mechanical and civil engineering, as well as in physics and materials science.
Plasticity theory is a tool used in structural analysis to evaluate the ultimate strength and the post-elastic behavior of ductile structures, explains Paglietti (strength of metals and engineering, U. of Cagliari, Italy), but its application to real materials is undermined by the evolution law of the yield surface, also known as the work-hardening
This book presents select proceedings of the International Conference on Trends and Recent Advances in Civil Engineering (TRACE 2022). It focuses on the latest research developments in structural engineering, structural health monitoring, rehabilitation and retrofitting of structures, geotechnical engineering, and earthquake-resistant structures. The book also covers the latest innovations in building repair and maintenance, AI and blockchain in structural engineering, advancements in the design of earthquake-resistant structures, and sustainable materials for rehabilitation and retrofitting. The contents of this book are useful for researchers and professionals working in structural and geotechnical engineering and allied areas.
It is well-known that the topic of composite mate- rials affects many engineering fields, such as civil, mechanical, aerospace, automotive and chemical. In the last decades, in fact, a huge number of scientific papers concerning these peculiar constituents has been published. Analogously, the industrial progress has been extremely noticeable. The study of composite materials, in general, is a challenging activity since the advancements both in the academia and in the industry provide continually new sparks to develop innovative ideas and applications. The communication, the sharing and the exchange of views can surely help the works of many researchers. This aspect represents the main purpose of this Conference, which aims to collect high-level contributions on the development and the application of composite materials. The establishment of this 21st edition of International Conference on Composite Structures has appeared appropriate to continue what has been begun during the previous editions. ICCS wants to be an occasion for many researchers from each part of the globe to meet and discuss about the recent advancements regarding the use of composite structures, sandwich panels, nanotechnology, bio-composites, delamination and fracture, experimental methods, manufacturing and other countless topics that have filled many sessions during this conference. As a proof of this event, which has taken place in Bologna (Italy), selected plenary and key-note lectures have been collected in the present book.
