Composite Material Model For Impact Analysis Composite Material Model For Impact Analysis An uncontained turbine engine failure is a significant concern for airworthiness of aircraft and their safe operations. Over 340 uncontained failures are identified by SAE Aerospace Information Reports (AIR 4003, AIR 4770, SP 1270) for the period from 1976 to 1989. These occurrences also identify fan and compressor disks and blades as some of the most critical and potentially dangerous failures. Over half of the reported cases involve the fan and compressor disks and blades, making accurate analysis of these failures and the structures they interact a high priority. The explicit finite element program LS-DYNA is the industrys choice for this type of high strain rate analysis. The FAA certification process, continued airworthiness requirements, and maintenance regulations are the main oversight mechanisms to ensure safety of operation for aircraft engines. The complexity of these machines and the expense involved in testing for certification makes computer simulation analysis a desirable tool that can enhance this process for both the government and industry. Various LSDYNA material models have been developed under the sponsorship of the FAA Aircraft Catastrophic Failure Prevention Research Program. The need exists for development of a new composite material model and further support and development of fabric models. This proposal outlines the capabilities and plan of ASU to support this research.
