    Hi all, I'd like to model composit

    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 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

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

    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?

    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...

    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...
