• Abstract:
  As a part of the FAA’s Aircraft Catastrophic Failure Prevention Program (ACFPP), the LS-DYNA material model *MAT_224 was developed for computational modeling of high-speed impact problems, e.g., an actual turbine engine blade release event. Material impact imposes a temperature rise, which is estimated in *MAT_224 by the Taylor-Quinney Coefficient (TQC) that describes the percentage of plastic work converted into heat energy.
