The NAFEMS Composites Working Group (CWG) was formed in the Fall of 2010, following strong demand from within the NAFEMS membership for an increased level of activities related to the application of numerical methods to the analysis and assessment of composite materials. Prior to this date, NAFEMS had already developed a number of publications and hosted several events which were of direct relevance to composites. Since 2011, the newly formed working group has been acting as the focal point for NAFEMS activities related to composite materials. Currently, the group includes several of the leading practitioners in the field of composites in finite element (FE) analysis.
