Under the existing Platform grant, the Unit for Stress & Damage Characterisation (USDC) has become a world-leading centre for excellence. Platform grant funding was an essential aspect in maintaining and developing our measurement and imaging capability. Over the 4 years since the Platform grant begun it has supported and helped us win 80 research grants including 29 Research Council (8,519k), 32 industry (4,983k), and 20 other (3,343) grants dependent on the Unit's facilities and staff. This portfolio of funding has enabled us to develop a stable research and development infrastructure analogous to the instrument scientist roles at large-scale facilities. Our post-doctoral fellows have been predominantly supported on grant income but Platform grant funding has ensured continuity of appointment. Further it has enabled them to follow a mixed programme comprising: a) world class experiments written up in world class journals (170 papers in the 3.5 years in addition to a similar number of conference proceedings); b) adventurous or speculative proof of concept studies often leading to follow-on funding; c) collaborations with other UK and international academics to provide new insights not available to them at their host institutes; d) visits abroad and work with visitors attracted to the Unit.This environment has been a very successful breeding ground for training and developing independent researchers. Six of its PDRAs have gone on to full lectureships; five have taken up instrument scientist posts at international large-scale facilities.The current proposal will allow the USDC to strengthen its position by developing capability and to thereby undertake world-leading experiments. At 1.7M and 156 man months it represents some 10% of the funding of the Units activities and 15% of its workforce. We anticiapte a high level of continutuity of support, indeed our existing portfolio reaches well into the period of this grant (see our man power chart in the justification of resources).In particular the grant will enable us to:a) extend our measurement capability beyond existing time and length scale confines to enable a wide range of ground breaking in situ and ex situ studies;b) undertake in situ studies of corrosion, cracks and failure processes;c) study the relationships between structure and properties in composites and architectured solids;d) observe transition processes in functional 'Smart' materials.Research in these areas is timely as the developments in fabrication of these materials are matched by developments in the measurement and imaging capabilities.

在现有的平台赠款下，压力和损伤表征单元（USDC）已成为世界领先的卓越中心。平台赠款资金是维持和发展我们的测量和成像能力的一个重要方面。自平台赠款开始以来的4年中，它支持并帮助我们赢得了80项研究赠款，包括29项研究理事会（8，519 k），32项行业（4，983 k）和20项其他（3，343）赠款，这些赠款取决于该单位的设施和工作人员。这一资金组合使我们能够建立一个稳定的研发基础设施，类似于大型设施中的仪器科学家角色。我们的博士后研究员主要依靠赠款收入，但平台赠款资金确保了任命的连续性。此外，它使他们能够遵循一个混合方案，包括：a）在世界级期刊上撰写的世界级实验（在3.5年中，除了类似数量的会议记录外，还有170篇论文）; B）冒险或投机性的概念验证研究，通常会导致后续资金; c）与其他英国和国际学者合作，提供他们在主办机构无法获得的新见解;（d）到国外访问，并与被该股吸引的来访者一起工作，这种环境一直是培养和发展独立研究人员的一个非常成功的温床。其中六名PDRA已成为正式讲师;五名已在国际大型设施中担任仪器科学家职位。目前的提案将使USDC通过发展能力来加强其地位，从而进行世界领先的实验。它的工作量为170万人，156个人月，约占该股活动经费的10%和工作人员的15%。我们预计将有高水平的持续支持，事实上，我们现有的投资组合将在此赠款期间得到很好的支持。（请参阅我们的人力资源表中的资源说明）。特别是，这笔拨款将使我们能够：a）扩展我们的测量能力，超越现有的时间和长度范围，以便进行广泛的现场和非现场研究;B）进行腐蚀、裂缝和破坏过程的现场研究; c）研究复合材料和结构化固体的结构和性能之间的关系;d）观察功能“智能”材料的转变过程。这些领域的研究是及时的，因为这些材料的制造发展与测量和成像能力的发展相匹配。
