QUESTION:

Do you have a simple ANSYS/LS-DYNA bird strike example that I can use as a starting place?



ANSWER:

I incorporated an equation of state material model (apparently approximating a bird) I found in our database into a small symmetry model of a spherical 'bird' impacting an unsupported plate having the density of steel but with only 0.0001 times the stiffness. Read the attached input file into an interactive ANSYS session. It runs in seconds and will leave you watching an animation of the time varying displacement contours.

The input file is parametric ' edit parameters appearing near the top of the file to modify dimensions, initial velocity, and the duration of the transient.

ANSWER:

I incorporated an equation of state material model (apparently approximating a bird) I found in our database into a small ¼ symmetry model of a spherical `bird` impacting an unsupported plate having the density of steel but with only 0.0001 times the stiffness.
