Hi All If one engineer works as a calculation eng (R&D) but he needs to collaborate with the technician of the laboratory ( who seems to be not so much friendly with graduated engineers , even hostile) whom shows too much curiosity at the engineer's activity, to know what he is doing and how...

Hi All I just need to know how does a fatigue analysis software use the FEM model we load in it to calculate the life, cause i don't find it on manuals

Hi All a software I am using , doesn't give the centroidal results easily, does it really matter to use centroidal or elemental or nodal to be used in Fatigue analysis ?

Hi All having Quadratic shell elements, I see that I can obtain centroidal results in Ansys ?

Hello Everybody I would like to know, if i am supposed to conduct a multi axial fatigue analysis using Ansys (with 6 load cases) to be exported to Fe safe , which files should I save ano how can I agglomerate all the 6 load cases results in one output file ? cause in another software it was...

Hi All I am doing a modal and harmonic analysis Why aren't the resonance frequencies resulting equal in two cases if I drop the modal solution onto harmonic analysis system and if I don't drop and do the harmonic solution independently from Modal results ?

Hi everybody doing a modal analysis for a part of dimensions of 200 mm, when I request deformation for modal analysis results, I get some maximum values like 250, 400 in deformation results, which is somehow meaningless, specially becuase I have fixed my part ( a cyclinder) from two sides)...

Hi All I have experience with Abaqus , but I cant find the same procedure existing in Abaqus to define self contact in Ansys, also didn't find a tutorial on net. could anybody give some guidelines ?

Hi All for the fatigue curve points estimation ( for each stress level) which of the two is more reliable

Hi all How much stiffness does a stewart platform introduce to a system ?

Hi All I have a pipe ( clamped from one side ) while a lateral load and a moment is being applied to the other end. due to the geometry difficulties, I need to install the strain gages near the loading end, where also the fracture happens. the loads are being applied in a harmonic regime under...

Hi all Does anyone know whether the fracture surface changes if the stresses applied in the cycles change from proportional (desired) to non proportional ?

Hi All I have a simple question , when I choose a variable in my structural model to make it parametric, in Workbench, I see that the arrow only exists from the step and goes to the parametric but doesn't return to the step, I just want to create a set of results varying the quantities of a...

Hi all I am doing a structural and harmonic response analysis, I have a cylinder like part with some complications in geometry that's designed in Catia and imported in various formats like igs, step and parasolid, set up as b_spline in compatibility in Catia(which i set it after getting invalid...

Hi All I would like to know a history and the first time that the flexible componenet was used on the auto exhaust systems. seen that the old cars don't even have it , but you haven't seen probably many ruptures in the exhaust pipe, I was just curious to know its necessity of use

Hi All reading about application of full spectrum in rotary machine diagnostics, I have difficulty in understanding how a shaft rotating in one single direction and bi-directional vibration, that constitutes its full spectrum diaghram, can have a two contrasting rotations, forward and reverse...

Hi All shall someone tell me what are the sources of vibration on corrugation machines, and which points ought to be measured to assess the modal analysis ?

Hi all could you please indicate some pratical problems that only one of the 3 methods subspace or Lanczos or AMS are specifically applicable and not other ones , when conducting a frequency analysis in Abaqus ?

Hi All I'd like to know ,what are the benefits of designing Composite materials with CATIA composite materials if you don't end up with FEM analysis of the plys ?

Hi All while simulating a coupled thermal stress analysis, I noticed that I only get the NT11 results, and no stress it's an RC beam, the elements are chosen accordingly : coupled temp disp I have applied one step as initial temp applied to parts :25° as predefined field in all part then...
