All new materials or designs need to go through certification and validation. This involves a full suite of tests to be carried out to prove not just that the assembled system works but to prove the material and establish the design allowables.
The properties of metallic materials were well founded and how to use them was well known. Composites on the other hand are more complicated. If the configuration of material is changed in a composite, even if similar fibres and matrix material are used, then effectively a different material is made. Therefore there is a lot of testing that must be carried out to replace the years of testing that built up the empirical equations used for metallic structures.
This project is therefore focusing on taking the standard tests and trying to build virtual equivalents of them. The aim is to save time and effort used in the testing of materials and assembled systems.

Over recent years, there has been a large push towards developing techniques to facilitate Whole Life Cost (WLC) modeling, largely due to the increased interest in longer timescale projects and programs, combined with the emergence of system-of-systems and network enabled capability concepts. This change in the implementation and management of large scale projects has necessitated the development of alternative methods of evaluating performance. This current work seeks to address the shortfalls in current costing methodologies when applied to these highly flexible environments, and to propose a conceptual model for dealing with the encountered complexities. The approach has a fundamental role and potential significance in the future of whole life costing for NEC but can also offer a potential paradigm shift in costing in traditional engineering environments.
