The Residual Stress State Due to a Spherical Hardbody Impact

  title={The Residual Stress State Due to a Spherical Hardbody Impact},
  author={B. L. Boyce and Xi Chen and John W. Hutchinson and Robert O Ritchie},
The current study assesses the residual stresses and remnant damage caused by a spherical projectile impacting upon a flat surface. The immediate application of this information is to the problem of foreign object damage (FOD) associated with the ingestion of debris into an aircraft turbine engine and the subsequent reduction in component lifetime. The work is focused on two primary features: (i) the development of numerical models for the evaluation of the deformation and stresses associated… CONTINUE READING
