  3. N12A-T006: Total Fatigue Life Assessment of Complicated Structures

    Release Date: 01-26-2012Open Date: 02-27-2012Due Date: 03-28-2012Close Date: 03-28-2012

    OBJECTIVE: Develop innovative concepts for coupling analytical and/or numerical techniques to evaluate total fatigue life of structures involving complicated two-dimensional (2D) and three dimensional (3D) cracks of planar and non-planar shapes. DESCRIPTION: Cracks in aircraft structural components are of complex shapes and subjected to complicated load histories. Too often, crack growth analysis is carried out by oversimplifying the problem through the use of simple crack shapes and one dominant loading.

  9. N12A-T012: Application of Auxetic Textiles to Military Protective Clothing

    Release Date: 01-26-2012Open Date: 02-27-2012Due Date: 03-28-2012Close Date: 03-28-2012

    OBJECTIVE: Research and development of auxetic textiles for use in military protective clothing (e.g. body armor). DESCRIPTION: Usually, when a textile is stretched, it becomes longer in the direction in which the load is applied, and narrower in the transverse direction. Auxetic textiles, however, become fatter when stretched and thinner when compressed, exhibiting negative Poisson"s ratio.
