    Hi all, I'd like to model composit

    Hi all, I'd like to model composite cylinder under pressure with CAX elements. How to orient material (directions of Er, Eq, Ez)? Thanks in edvance.

    Abaqus benchmark

    Hello, I just wonder if anyone tried Abaqus benchmark "1.1.4 Thick composite cylinder subjected to internal pressure"? I've tried all of it: thickcompcyl_2el_nonuniform.inp , thickcompcyl_1el_sectorient.inp , thickcompcyl_4el_orient.inp , and thickcompcyl_8el.inp and neither one give result even...

    Plugin with TreeList

    I created the plugin for Abaqus as an AFXList (Abaqus GUI Toolkit User's manual, Section 3.3.1 Lists) and it works (send selected item to main script). Now I want to create similar ones, but using FXTreeList (ibid., Section 3.5.1 Tree list) or AFXOptionTreeList (ibid., Section 3.5.1 Option tree...

    How to create correct geometry of coil in Abaqus/CAE?

    Hi, I try to create a spiral coil (fraction of it) with such parameters: springRad = 3.835 wireRad = 0.2 helixAngle = 78.2 numTurns = 0.25 (can be any) and therefore pitch = 2*pi*springRad/tan(helixAngle*pi/180) by p.BaseSolidRevolve(angle=numTurns*360.0, flipPitchDirection=OFF...

    How to print stress in cylindrical CS?

    With command "*EL PRINT, ELSET=ElementsSet, POSITION=NODES" , I can print stresses for each node of ElementSet in dat-file and such stresses are in Global (Cortesian) CS. How to print stresses in Local (Cylindrical) CS? Thx

    BC for open-coiled spring

    Hello to all, Asking for help with practical advice on simulation OPEN-COILED HELICAL SPRING WITH LARGE DEFLECTION (springs with ends fixed against rotation): Imagine a very long spring which is fixed at one end, and the axial force (or displacement) is applied to another end. As is known, in...

    Curvature Analysis

    Carrying Analysis -> Curvature, we can save the information as ASCII-file (see picture) or Excel-file. How to convert Param(eter) into the coordinates of the points? Thank you.http://files.engineering.com/getfile.aspx?folder=d737a07b-6d5f-42e9-bf4d-e167c1838fab&file=Curv_anal.jpg

    Datum Point Ratio

    I'm trying to create a Datum Point - Offset Ratio - End of Curve - (a straight line length of 50 mm, offset ratio 0.01) and it does not work - point is created at the end of the line. I've checked config.pro and Model Properties - all right. Then I did the same thing, but with Offset Real 0.5 mm...

    Rotational connection

    I need to create a rotational connection between two nodes: three orthogonal beams rotate from initial to final position). In Creo it's easy to do with help of Transform. In Abaqus, for instance, it can be done with Cardan connection. How to do such thing in Creo/Simulate? Thank...

    Plotting stress-strain curve for rubber

    Hi All, I'd like to plot stress-strain (stretch) curves to compare different rubber materials (I have Mooney or Ogden constant already). For Mooney-Rivlin material, I can calculate stress S as S=(2C1+2C2/d)(d-1/d^2) where C1 and C2 are Constants and d is the stretch ratio, defined as the...

    Spring Property Definition

    For simplicity, say, we have assembly of two components, and we want to analyze one component and model another as spring (to ground). How to analyse the second component in the separate analysis, to calculate all six components of stiffness (which are necessary for filling the Spring Property...

    How to create parametric model of solid ring?

    Hi all, There is a good example of parametric of a shell model of cylinder (cylsh_buck.inp) in Abaqus examples folder. Does anybody know/have a similar template for solid model (full, not just a portion of section, a multilayered tube of c3d8 elements)? Tanks in advance.

    How to create Brick elements?

    For simplicity, let’s consider flat plate. I seeded surfaces, then selected followings option, and successfully created Quad shells. Now I try to create solids (I expect to create Brick elements), but get Tetra elements (not even Wedge). Is it possible to do it in WF4...

    Inertia relief

    If in my model I have mass elements and want to use an inertia relief option, do I need to create gravity or centrifugal forces to analyse effect of mass forces, or 'inertia relief' will do it for me? If last one is correct, then what will be a direction of mass forces (in other words, what will...

    Measure angle: convert to rotation angles

    How to convert direction cosines (which I can got from Measure angles between line and surface, for example) to ratation angles (around each coordinate axes? Fred

    How to calculate angles for compound rotation?

    In my model I'd like to rotate [surface] from one orientation to another. The geometry is created in Pro/E (Wildfire 3 and up), so I can measure angles between these two surfaces as three angles between the normal to the surface and the coordinate axes. In Abaqus, I can create a compound...
