This scientific event is a new edition of the High Performance and Optimum Design of Structures and Materials Conference and follows that originated in Southampton as long ago as 1989 and the Structures under Shock and Impact that started in Cambridge, Massachusetts, also in 1989 The use of novel materials and new structural concepts nowadays is not restricted to highly technical areas like aerospace, aeronautical applications or the automotive industry, but affects all engineering fields including those such as civil engineering and architecture. The conference addresses issues involving advanced types of structures, particularly those based on new concepts. Contributions will highlight the latest development in design and manufacturing issues. Most high-performance structures require the development of a generation of new materials, which can more easily resist a range of external stimuli or react in a non-conventional manner. Particular emphasis will be placed on intelligent structures and materials as well as the application of computational methods for their modelling, control and management. The conference also addresses the topic of design optimisation. Contributions on numerical methods and different optimisation techniques are also welcome, as well as papers on new software. Optimisation problems of interest to the meeting involve those related to size, shape and topology of structures and materials. Optimisation techniques have much to offer to those involved in the design of new industrial products, as the appearance of powerful commercial computer codes has created a fertile field for the incorporation of optimisation in the design process in all engineering disciplines. The performance of the structures under shock and impact loads is another objective of the meeting. The increasing need to protect civilian infrastructure and industrial facilities against unintentional loads arising from accidental impact and explosion events as well as terrorist attacks is reflected in the sustained interest worldwide. While advances have been made in the last decades, many challenges remain, such as developing more effective and efficient blast and impact mitigation approaches than those that currently exist or assessing the uncertainties associated with large and small scale testing and validation of numerical and analytical models. All of that aimed to a better understanding of critical issues relating to the testing behaviour, modelling and analyses of protective structures against blast and impact loading.
