I have just started working towards my project which is comparison of different approaches in the design of laminated glass and I want to model Laminated glass in Abaqus. I have the data for shear modulus, youngs modulus and Poisson ratio at different load duration and different temperature. In order to model this LG model I have a viscoelastic material sandwiched between two plates of glass. So far I have understood that I will need to input the coefficients of prony series in order to define the material. I do not know how to find these coefficient. I also found out that we can give direct input of test data to abaqus. Can anybody throw some light on this subject. Also if you have any reference material which can give better understanding, can you please post the links??
