That will require develop- ment of a comprehensive set of simula- tion tools that connect composites from their birth in manufacturing to their life- time prediction. With these tools, com- posites professionals can advance the certifcation of composite products by analysis validated by experiments, but to do so, current and future generations of engineers must be taught how to use the tools. To do that, software develop- ers must work with industry, academia and government, and a platform like cd- mHUB is the vehicle that will make that possible. This cloud-based platform, then, can be the "meeting place" for the composites community, where sustain- ing sponsors, simulation tool providers, and developers and tool users can work together toward this common goal. The cdmHUB brings to that commu- nity a host of benefts: • Education in the use of commercial and emerging simulation tool use • Development of new simulation tools for composites manufacturing • Evaluation of technology-readiness levels of emerging tools • Establishment of protocols for simulation tool validation and verifcation • Access to data sets required in composites manufacturing simulation • Forecasts of the unmet needs in simulation tool functionality • New tool development for composites design, manufacturing and processing simulation • Development of research needs analysis for simulation tools As noted by Dr. Waruna P. Seneviratin, technical director/scientist at the Nation- al Institute for Aviation Research (NIAR, Wichita, Kan.), building-block analysis validated by testing is a rational multi- level developmental model used by many aerospace companies to certify metallic and composite structures. The cost and time involved in performing experimental tests escalates as the OEM moves from lamina coupons level to details level and, eventually, to component level. So there is the potential for signifcant cost and time savings, if some of the higher level testing could be reduced through the use of validated analytical models. Dr. Seneviratin points out that if we are to fully realize the advantages of analy- sis supported by test, then we must in- vestigate the accuracy and validity of the current state-of-the-art virtual analysis tools in terms of predicting the results of experimental physical tests. When these tools are validated, such analytical mod- els can then be used to model more com- plex geometries and reduce the burden of certifcation testing requirements. Realistically, a lot of work must be done just to get all the existing composites simulation tools gathered into one cyber- community so they can be assessed and brought to the same maturity level. The cdmHUB is designed for that very pur- pose. In the near future, the aerospace community will be able to log on to the cdmHUB to begin that process. But … why stop at the aerospace in- dustry? These same tools can be used in the automotive, marine, consumer goods and other industries. What we ac- complish here will beneft everyone.
