    Two Poisson ratios in Abaqus membrane element

    Hi all, In Abaqus membrane element, there are two Poisson ratios can be set. One is the Poisson ratio of the material of the membrane and the other one is called "effective section poisson ratio", which can be set to 0 in order to fix the thickness of the membrane. Does anyone know what is...

    huge element distortion even with ALE adaptive meshing

    Hi Abaqus gurus, I am working on a simple 2D simulation with two circles. The inner circle is inflated with a constant pressure (3000pa). The material is a simple linear elastic model (E=2000, poisson=0.45). Even I have used ALE adaptive meshing to control mesh distortion, the final result I...

    Abaqus early termination in an inflation simulation with ALE

    Hi all, My Abaqus/explicit ALE simulation terminates before the target pressure load can be achieved. The geometry is consisting of 4 concentric circles, and one other circle which will be inflated with a pressure (DSLOAD). Due to this expansion, ALE is used to control mesh distortion. I...
