Abstract:

Simulating uncontained engine fragment impact to composite aircraft structures requires material models, which can accurately account for the deformation, damage, and failure experienced during these highly dynamic events. The FAA Aircraft Catastrophic Failure Prevention Program sponsored the development of a new material model known as MAT_213 to model composite impact, which has been implemented into the commercial finite element software LS-DYNA. This report provides results for stacked-ply T800/F3900 carbon fiber reinforced polymer composite validation tests conducted at room temperature with uniaxial tension and compression loads applied at quasi-static rates by Arizona State University. Stress concentration validation tests were also conducted on stacked-ply specimens with a centered hole. Digital Image Correlation was used to obtain the experimental surface strain contours. MAT_213 was used to conduct simulations comparing stress-strain relationships, strain profiles, and displacement results to the experiments. The MAT_213 material inputs were obtained from specimen tests performed previously. Additionally, as part of this study, delamination tests were conducted using end notch flexure and double cantilevered beam specimens to characterize mode I and mode II fracture properties of the T800/F3900 composite. These experimental results were used to build models with MAT_138 cohesive zone elements for the interlaminar polymer matrix between the composite ply layers modeled with MAT_213. The test results were necessary to calibrate numerical inputs to the traction separation laws governing the delamination behavior. Scanning electron microscope analysis was also utilized to examine specimens in the untested, damaged, and failed states. The results provided insight to the microstructural damage induced from manufacturing, specimen preparation processing, and loading of the T800/F3900 composite.
