The Life of Structures: Physical Testing covers the proceedings of a seminar of the same name. The said seminar is focused on the actions on structures and the performance of existing populations of structures; the properties and performance of building materials; and the internal and external environments of buildings. The book covers topics such as the methodology for the prediction of the life of existing structures; reliability of service-proven structural systems; and some effects of micro-environment on materials. Also covered are subjects such as the assessment of structures through field measured dynamic response; physical properties of structures investigated by dynamic methods; and the stiffness damage test. The text is recommended for engineers who would like to know more about the strength and lifespan of structures, as well as the effectivity of the materials involved in their construction.

Engineers need to be able to test the flammability of the materials they use in buildings and other structures. However, the range of test procedures and regulations in this important area is often confusing. Flammability testing of materials used in construction, transport and mining provides an authoritative guide to current best practice in ensuring safe design. The book begins by defining flammability and the main types of test available. Building on this foundation, a group of chapters then reviews tests for key materials used in buildings and their contents. There are chapters on wood, external cladding and sandwich panels as well as the flammability of walls and ceilings. Tests for furniture fabrics, cables and electrical appliances are also reviewed. A final group of chapters discusses other types of test, particularly in the transport sector, including chapters on flammability testing for railway passenger cars, aircraft, road and rail tunnels. With its distinguished international team of contributors, Flammability testing of materials used in construction, transport and mining is a standard reference for civil and transport engineers in particular. An authoritative guide to best practice in ensuring safe design Defines flammability and the main types of test available A vital reference source for civil and transport engineers

"Long Term Durability of Structural Materials" features proceedings of the workshop held at Berkeley, CA in October, 2000. It brought together engineers and scientists, who have received grants from the initiative NSF 98-42, to share their results on the study of long-term durability of materials and structures. The major objective was to develop new methods for accelerated short-term laboratory or in-situ tests which allow accurate, reliable, predictions of the long-term performance of materials, machines and structures. To achieve this goal it was important to understand the fundamental nature of the deterioration and damage processes in materials and to develop innovative ways to model the behavior of these processes as they affect the life and long-term performance of components, machines and structures. The researchers discussed their approach to include size effects in scaling up from laboratory specimens to actual structures. Accelerated testing and durability modeling techniques developed were validated by comparing their results with performance under actual operating conditions. The main mechanism of the deterioration discussed included environmental effects and/or exposure to loads, speeds and other operating conditions that are not fully anticipated in the original design. A broad range of deterioration damage, such as fatigue, overload, ultraviolet damage, corrosion, and wear was presented. A broad range of materials of interest was also discussed, including the full spectrum of construction materials, metals, ceramics, polymers, composites, and coatings. Emphasis was placed on scale-dependence and history of fabrication on resulting mechanical behavior of materials.

Nowadays, it is quite easy to see various applications of fibrous composites, functionally graded materials, laminated composite, nano-structured reinforcement, morphing composites, in many engineering fields, such as aerospace, mechanical, naval and civil engineering. The increase in the use of composite structures in different engineering practices justify the present international meeting where researches from every part of the globe can share and discuss the recent advancements regarding the use of standard structural components within advanced applications such as buckling, vibrations, repair, reinforcements, concrete, composite laminated materials and more recent metamaterials. For this reason, the establishment of this 19th 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 Porto (Portugal), selected plenary and keynote lectures have been collected in the present book.

Thematerialsusedinmanufacturingtheaerospace,aircraft,automobile,andnuclear parts have inherent aws that may grow under uctuating load environments during the operational phase of the structural hardware. The design philosophy, material selection, analysis approach, testing, quality control, inspection, and manufacturing are key elements that can contribute to failure prevention and assure a trouble-free structure. To have a robust structure, it must be designed to withstand the envir- mental load throughout its service life, even when the structure has pre-existing aws or when a part of the structure has already failed. If the design philosophy of the structure is based on the fail-safe requirements, or multiple load path design, partial failure of a structural component due to crack propagation is localized and safely contained or arrested. For that reason, proper inspection technique must be scheduled for reusable parts to detect the amount and rate of crack growth, and the possible need for repairing or replacement of the part. An example of a fail-sa- designed structure with crack-arrest feature, common to all aircraft structural parts, is the skin-stiffened design con guration. However, in other cases, the design p- losophy has safe-life or single load path feature, where analysts must demonstrate that parts have adequate life during their service operation and the possibility of catastrophic failure is remote. For example, all pressurized vessels that have single load path feature are classi ed as high-risk parts. During their service operation, these tanks may develop cracks, which will grow gradually in a stable manner.
