TECHNICAL WORKING GROUPS DATA REVIEW WORKING GROUP

Dr. Rajv Naik, Pratt and Whitney Vision Statement To provide the final technical/editorial review of all data prior to review by the full Coordination Group; provide a review of the application of the data documentation requirements to the actual data being supplied; develop formats for data presentation in the handbook; and establish the data documentation requirements for the handbook. Goals

Formulate guidelines and requirements for data submission, data documentation, data

analysis, and data review for all CMC data that is submitted for inclusion in the

handbook.

Review the data and the data analysis of data sets that are submitted for inclusion in the

handbook.

Develop formats for data presentation in the handbook and for storage of data in

electronic databases.

Develop and document statistical methods for data pooling and data analysis of CMC

data.

DESIGN AND ANALYSIS WORKING GROUP Dr. David Thomas, Rolls-Royce Corporation Mr. Mark Noe Vision Statement To be an authoritative source for design, analysis, and verification information for the validation and certification of CMC engineered structures. Goals To provide information on design and analysis certification methods and options, the level of

substantiation information required, and formats required in validation and certification processes.

To specify material property and performance input and validation data needed for design and analysis of CMC components

To identify test parameters to produce those data, and identify analysis considerations in interpreting such data, and to ensure compatibility with design needs

To identify approach options for the design and analysis of CMC structures and joints To ensure future relevancy of the handbook by maintaining an up to date survey of the

current state of the art capabilities within the design, analysis and lifing communities for CMCs
