| Description: | Bird strike analysis using a rubber projectile with rate effects impacting a rigid plate. The rubber projectile is used to represent the "bird material" and is modeled using *MAT_SIMPLIFIED_RUBBER (MAT_181). Gelatin rebounds elastically (until tension failure). Gelatin appears to soften at higher strain rates. These effects are included in the model. Two types of force vs. change in gauge length at different strain rates are tested.
