Hi FEA way, Thank you for the response. Sorry for confusion but my actual question was how to transform stiffness matrix for generalized plane strain elements (CAX). It could be done with Reuter's matrix. Regards.

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.

Thank you, FEA way. My bad, I didn't notice that the result was normalized. Problem solved.

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...

Hello, Seeking Help: Can anyone share a copy of the following articles: "P.C. Bregman, M. Kuipers, H.L.J. Teerling, W.A. van der Veen. Strength and stiffness of a flexible high-pressure spiral hose. Acta Mechanica 97, 185-204 (1993)" and "B.A. van den Horn & M. Kuipers. Strength and stiffness...

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...

Below is Python code for creating the described springs, maybe this will clarify my question: from abaqus import * from abaqusConstants import * springRad = 3.835 wireRad = 0.2 helixAngle = 78.2 pitch = 2*pi*springRad/tan(helixAngle*pi/180) numTurns = 0.25 # Correct spring radius but wrong...

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...

Mustaine3, Thank you for your reply. Yes, it will work manually, but my question was how to get this in dat-file.

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

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...

I just wonder if somebody try to install and use pypbs on Abaqus 6.14? Will above described approach works in such case? Thanks.

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

Solution is default_dec_places in config.pro - I found this advice in https://www.ptcusercommunity.com/thread/55997

Thanks. What it should be?

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...

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...

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...

Hi Pierre, I have a similar problem, but in the previous step my model was plastically deformed. Thus I also cannot run the next step directly, but must run restart instead of it. For some reasons, XFEM does not work with restart (there is no XFEM output in odb result file). Can you send me your...
