Hello all,

I am fairly new (a few weeks) to Abaqus (6.13) so please elaborate on any topic. In my research, before posting here, I have came across many terms/processes that I don't understand such as Implicit/Explicit integration, linear/non-linear dynamic analysis, mass scaling, time scaling, subcycling, eigenvalue extraction. So please when answering my questions to come elaborate as much as possible for me.

I am used to 2D and 3D punching of  a thin film. Now I want to start testing a viscoelastic film using the same geometry however now I have to change my test method to a time-dependent test such as creeping. I have been doing my previous tests by not introducing a load but introducing a certain ending strain I want to obtain which is 10% compression into the film(strain controlled). Now, to have similar data, I want to ultimately have the creep test go into the strain reaches this same 10% yet I need to do this by defining a load now. 

What load do I apply? I am trying to punch a specific geometry of a punch (analytically rigid) into the film so I don't think I should do a pressure load. Contact force seems the most reasonable. Also, do I calculate the force as F=(delL)*(E)*(A)/(L0)? Assuming this is the force I want to apply how do I know what times to use in my amplitude?

My material properties that make this film viscoelastic are the following (the viscoelastic numbers are from a paper on a glass above the glass transition temperature) :
Units are in SI
Density: 1.05
Elastic: Y.modulus: 2000000000 Poisson's: 0.35  
Viscoelastic: Prony-time domain: (list in format of gi,ki,taui starting form 1 to 7): (.029,0,3),(.579,0,4.5),(.372,0,4.5),(0,0.5,10),(.016,0,150),(.0008,0,10000),(.0013,0,20000)

Also if I have to raise my my time to a very high number how do I make sure that it still simulates in a reasonable amount of time without sacrificing data that makes physical sense. Any recommendations would be greatly appreciated!

Thanks,

Sean
