During the design stage of any material for structural applications, it is mandatory to ensure that the structures are safe under operation throughout the desired service life. In order to achieve this, it is required to understand the specific mechanical performance of the material for that intended application. Hence, an appropriate choice of mechanical testing, including the test type, geometry of the specimens and test setup is important. From the experimental results, it is possible to design the structures using analytical or semi-empirical models. Another approach that is getting increasingly attractive is the hybrid experiment-numerical approach, where the material properties determined from the experiments are input into the finite element analysis for simulations at the component or structure level. Virtual testing has the advantages of simulating complex geometries and materials saving. In view of this, this book is emphasising how to appropriately design for the experimental and/or numerical analysis based on an intended application. The aim is to give exposure to the readers on engineering practice from design until implementation.
