    Measuring a radial loaded shaft

    Hi rb1957, Thanks for jumping in this thread. In fact I was expecting to have different gains for the two planes (factor_I and factor_P) but then also have two different gains when planes were at 45deg from the radial load (sqrt(2)/2*factor_I and sqrt(2)/2*factor_P)... Concerning your "90...

    Measuring a radial loaded shaft

    Dear experts, In order to measure radial load on a shaft, 8 strain gauges on two full Wheatstone bridge circuits have been used. Each bridge circuit refers to a measuring plane (namely I and P). Radial force as well as voltage signal from two planes is measured for 5 different shaft angular...

    Fatigue testing

    Dear experts, I have access to a fatigue testing machine (tension-compression) and have some questions about how to properly define and analyze the data we can extract from. I am interested in characterizing material behavior (mainly steel, cast iron, aluminum and magnesium) on the high cycle...

    Grinding composite plate

    Thank you both for your interest in this topic. Not sure I fully understant Mike's suggestion. Do you have some place I can get more info on the process? Plates are already made. I do know that is feasible to grinder them, as we used to do it in-house. But we struggle to find someone outside

    Grinding composite plate

    Dear experts, We are looking for a supplier that could grind a composite plate (epoxy resin matrix reinforced with glass roving fabric). Plates would be about 2200x1300mm. Any hints? Thank you in advance

    Result file items control in workbench (outres command)

    As Flash3780 said, in the APDL command inserted, have a look at Definition>Step Selection Mode

    Shape Optimization tool

    Hello, You should activate beta options to see the Shape Optimization tool at 14.5 (at the project page, Tools>Options>Appearence: check Beta Options) Regards,

    Submodelling in ANSYS 14.5

    Hi, have a look here: http://www.edr.no/blogg/ansys_bloggen/submodeling_in_ansys_v14_5 In 14.5, no need for APDL commands (although I have seen that it duplicates the rst file of the coarse model...) Good luck

    Countersunk friction head diameter

    Thank's Screwman and CoryPad for your interest. I was able to find what I was looking for in the document written by Mr. Friedrich.

    Countersunk friction head diameter

    Dear experts, For a countersunk bolt DIN7991 M6, what average friction head diameter should be taken into account for its calculation? Nothing appears to be stated in VDI 2230:2003 for countersunk bolts I have found in http://www.hexagon.de/info112/index.htm that DKM = (Da+Di)/SQRT(2) for 90deg...

    Fatigue data for A6Z1 magnesium alloy

    Hi, I am looking for fatigue curves of unnotched A6Z1. In "Smithells Light Metals Handbook" I have found some data for R=-1. I have found also on MIL-HDBK-5H some curves for AZ31B-F (figure 4.2.1.4.8 (a)). It is stated that "AZ61A is much like AZ31B in general characteristics" but if I compare...

    ANSYS Bonded contact problem

    Mitch, If both bodies are already in touch and you have created a multibody part I don't understant why you had to define a bonded contact in your initial model. Are you sure that no gap exists between inner and outer section due to the boolean operation?

    ANSYS Bonded contact problem

    Mitch, When you say "I have then joined to create a single part" do you mean that in DesignModeler you have defined a multibody part? If so, (and asuming that now relative displacement has been done afterwards between those two parts), you should see that you have coincident nodes at the...

    Free program to see analysis results

    Hi, today I found this module: http://www.cadfem.de/produkte/ansys/cave.html never used but looks promising. Unfortunately, I don't think it's free..(I personally find disapointing that ANSYS doesn't provide an integrated (=included in the license fee) solution for 3D visualisation...of course...

    Ansys WB Nonlinear problem

    Crigido, It seems that geometry and loads are symmetric => if so, you could just study half of your model. I don't think that "Adjust to touch" setting in your contact definition is to be used in this case => I'd rather leave it to Add Offset, Ramped with 0 offset (assuming that initially...

    ANSYS Workbench-scripting

    Hi Sameer Try inserting the following APDL commands in the solution area of your simulation: SET,LAST NSORT,S,EQV,0 *GET,my_n_seqv_max,SORT,0,IMAX my_nx=nx(my_n_seqv_max) my_ny=ny(my_n_seqv_max) my_nz=nz(my_n_seqv_max) once you have pasted them, click on the Search Parameters button and the...

    Create different bodies with Design Modeller

    David, You might try: After creating first surface from sketch, use the freeze button to avoid next surface being merged to the first one.

    Ansys PCG Solver

    Hi Felix, Have you tried adding set,last before your *get code in /post1? When using Workbench environment, program automatically creates a variable (_PCGITER) where is stored the number of iterations done by the PCG solver. Carles

    Fatigue assesment of CFRP parts

    ESPcomposites, Thank you for your interesting comments. Our part is not supposed to see any impact, just a cyclic vertical force. Going through some papers found at the NASA archives, I have found: *for a [+-45]s, R=0.1 @10Hz sigma_max=52%UTS = 90MPa @1E6 cycles (at "Stifness reductions during...
