    G0 in Prony series

    Good afternoon, I want to create a viscoelastic material in Abaqus 6.9-2 CAE. Therefore I need to create a material in terms of density, elastic information (Young's modulus and Poisson's ratio) and viscoelastic information (In this case: Prony series). In the viscoelastic information section...

    Prony series to model viscoelastic behaviour

    To be clear: I don't know where to put the G0 from the Prony series. I'd like to create a viscoelastic material using Prony series. In the Abaqus 6.9-2 CAE manual I found I have to define a viscoelastic material by the next material behaviours: 1. Density: Density 2. Elastic: Young's modulus...

    Prony series to model viscoelastic behaviour

    Hello again. Thank you for your response. I have the Prony series now in term of G0, g1 to g5 and tau1 to tau5. Now I'm confused what to do with the G0 term? I cannot put in the viscoelastic data table, since it starts with g1. I used the definition of the Prony series from the Abaqus manual...

    Williams-Landel-Ferry equation

    I'd like to use the Williams-Landel-Ferry equation to create a mastercurve. I'd like to have a frequency range of 1 to 1000Hz at 23 degrees. The DMA machine has a frequency range of 1 to 200Hz. Therefore, I did a temperature sweep from 23 to 140 degrees Celsius. I think I made an error here. I...

    Prony series to model viscoelastic behaviour

    I'd like to model a viscoelastic material in Prony series terms in Abaqus 6.9-2. I have DMA measurements (shear loss and shear storage moduli vs frequency) for various viscoelastic materials in terms of frequency Prony series, so g_i's and tau_i's. In Abaqus, I create a material in terms of...

    Importing ACIS into ABAQUS

    It works! In SW: Save as\ACIS (*SAT)\OPTIONS\UNIT: METERS! Thank you!

    Importing ACIS into ABAQUS

    SolidWorks interprets the dimensions in the *.sat right, so I think the problem isn't there. In Abaqus the units cannot be found; it seems like input units are output units. Without scaling factor the beam length is 72 (no units) instead of 0.072 (scaled). Anyway, thanks for your response.

    Importing ACIS into ABAQUS

    Hello all, When I import a part into a *.sat (ACIS SAT) file into ABAQUS CAE 6.9-2, I need to scale the part by 1e-3. Why? mm to m? The ACIS file was drawn in SolidWorks. In SolidWorks, when I change units to meters instead of millimeters, I still need to scale the model by 1e-3 when...
