    Tan delta, viscoelasticity, DMA, and specimen size

    Thanks! Temperature and humidity are controlled. It is a latex-based polymer. I agree that dimension shouldn't influence the results and thanks for making the point about twisting bonds; breaking bonds gets into plastic deformation. I still need to convince myself (for sanity's sake) that...

    Tan delta, viscoelasticity, DMA, and specimen size

    Hi All, I'm trying to wrap my head around viscoelastic testing. I would expect greater energy loss (higher tan delta) at lower frequencies/strain rates for creep and strain relaxation reasons, and greater energy loss at higher frequencies as bonds in polymer chains are more pulled and broken...

    Hello All, I hope this is a simp

    Hello All, I hope this is a simple question that may help others as well. Until recently, my models (Abaqus/Explicit) have involved parts fastened together in the assembly but I now need to set one thing on top of another (for example, an object on a table), letting gravity hold them together...

    Pressurization - consistent in models with different material props?

    Hello all, I am modelling a single pressure vessel, looking at different materials and wall thickness. I'd like to pressurise the vessel to a specific pressure in the first step and carry out an analysis in subsequent steps. Using the fluid surface cavity approach, I'm aware of two methods of...

    Exporting ABAQUS output results

    Is there a way to do this with an Abaqus/Explicit job that doesn't require clicking through the 'Output Databases' tree to save pre-requested history outputs as XY data? I'd like to see the xy data from my history outputs without opening CAE. Thanks you.

    Automatic csv export of history outputs

    Hello All, I would very much like to have my Abaqus/Explicit jobs export the reqested history outputs as csv or other readable files either during or after the analysis. I don't want to open CAE and export each curve (or set of curves) manually. It looks like this is a bit easier in...

    axially varying pressure load - Help please

    I am working with a non-uniform pressure as well. I understand the "Magnitude" field to be a linear multiplier, basically. If the pressure value is correct in the distribution equation/specification, a magnitude of 1 should suffice. I think. Maybe someone could confirm this. I have operated...

    Normalizing Field Outputs

    Thank you Barten. I previously thought only history outputs could be modified like that. It's good to know field outputs can be modified with boolean operations as well! At first glance, it looks like the operations produce only one resultant frame and I would like to look at many to see a...

    Normalizing Field Outputs

    Hello All, I've found a lot of helpful information on this forum in the past but now I have come up against a wall. I would like to visualize the nodal displacements of a 2-part assembly as a result of "load-scenario 2" relative to the deformed geometry resulting from "load-scenario 1"...
