Hi,
Is there a function in ANSYS which can recreate the ABAQUS 'free body cut' behaviour? It lets you take a slice through the model and obtain the forces and moments acting about a point in the sliced cross section. I need it to check that a shell model of a wind turbine blade is seeing the...
I am coding up a non-linear dynamic simulation of some wind turbine blade test equipment. The blade is cantilevered from a mounting structure and fatigue tested by reciprocating a large mass that is mounted to the blade at the resonant frequency of the system. The blade and its mounting...
Hi Everyone,
I'm working on a BMX bicycle hub, and space is at a premium to say the least. This is because the design of the hub means that the bearings must be fitted underneath the driving sprocket, which has 9 teeth and is designed for a chain with a 1/2" pitch. This effectively places an...
Hi All,
I'm writing a MatLab script to read the Abaqus input file for a shell element model of a wind turbine blade and output its beam properties at various points along its length. The input file contains various data that spread across two lines, such as elastic properties for materials...
Hi,
I'm developing an in house code for analysing polymers. The algorithm I'm using to check when failure will occur is temperature dependent, so we need a formula for calculating how much the temperature will rise due to stress cycling. I've found the formula...
Hi,
Does anyone know how to view the stresses in different layers of a composite in Abaqus/Visualisation? At the moment I can only view the results in the top layer of the stack. I have outputted stresses at all levels in the laminate.
Thanks,
Pete
Hi,
I have a shell element model of a wind turbine blade in Abaqus. The company I'm doing the work for uses an in house mesh generator to build the model from information about the exterior surface of the blade and the lay ups, which I believe interfaces with PATRAN. I'm using Abaqus/CAE, so...
Hi,
I have modelled a wind turbine blade in Abaqus/CAE. It is made from a variety of different composite lay ups, so I have used composite shell elements to model it. I have some wind turbine specific simulation software, but it requires beam section properties (bending stiffnesses, shear...
hi, i'm working on modelling a wind turbine blade. I have loads derived from wind turbine simulation software which utilises a beam element model of the blade. This is in the form of a time history of the axial force, torsion moment, and a 2 bending moment and shear forces. I have built a full...
Hi,
I am working on a simulation tool for wind turbine blade fatigue testing.
The gif on this page is worth a thousand words...

I have written a beam element FEA code in MATLAB that allows a transient analysis to be performed. It works...
Hi,
I'm doing a frequency response analysis on a cantilevered beam. I'm interested in the moments along the length of the beam when it is being forced at its natural frequency. I've modelled it with beam elements and performed a modal analysis initially, with all the output file options...
