I'm modeling iPhone drop tests in ANSYS to look at the effects of various case geometries, however, I'm having a lot of trouble deciding on how I want to create the gorrilla glass material. Corning provides the Young's modulus, Poissons ratio, shear modulus, and density; thats about it. I don't believe this is enough to fully define the glass (I just want to see the principle stress effects, doesnt need to shatter necessarily). My question is: is there a material in the 18.1 ANSYS explicit dynamics materials library that is remotely similar? Float Glass is the only other glass I identified.

If you don't yet need to predict failure of the glass, then you have enough material properties to predict stress effects.
I recommend you try Transient Dynamics for simulating a drop test because I had good results and the solution times were reasonable.
I recently tried Explicit Dynamics and found that a simple problem ran for 33 hours on a mesh that was too coarse to be useful.
How can you study the creeping phenomena in transient dynamics?
Creep phenomena are on very long time scales. Fence14 is simulating drop tests, which means impact on a millisecond time scale.
