Discussion Overview

The discussion revolves around performing finite element analysis (FEA) on viscoelastic dampers, specifically using ANSYS software. Participants inquire about the appropriate version of ANSYS to use, seek tutorials, and explore the feasibility of manual FEA calculations.

Discussion Character

  • Technical explanation
  • Homework-related
  • Debate/contested

Main Points Raised

  • One participant questions whether to use ANSYS 11 or ANSYS Workbench 11 for FEA of a viscoelastic damper.
  • Another participant suggests that both ANSYS standard and Workbench can perform harmonic frequency response analysis, with Workbench being potentially easier to use.
  • A participant indicates plans to start with harmonic analysis and later conduct random frequency response analysis, requesting tutorials on viscoelastic dampers in ANSYS Workbench.
  • An undergraduate participant expresses interest in using Workbench for a viscoelastic model and asks about activating the Prony series for viscoelastic properties.
  • Another participant raises a question about the feasibility of performing FEA calculations by hand, specifically for stress and bending motion in uniform materials, and seeks resources for manual calculations versus software use.

Areas of Agreement / Disagreement

Participants express varying preferences for software tools and methods, with no consensus on the best approach for manual FEA calculations versus software use. The discussion remains unresolved regarding the effectiveness of manual calculations in comparison to software solutions.

Contextual Notes

Participants have not reached a consensus on the best practices for FEA of viscoelastic dampers, and there are unresolved questions regarding the activation of specific properties in ANSYS Workbench and the practicality of manual calculations.

Who May Find This Useful

Individuals interested in finite element analysis, particularly in the context of viscoelastic materials and those exploring both software and manual calculation methods in engineering applications.

I am trying to do a FEA of a viscoelastic damper. Should I use Ansys11 to do the analysis or Ansys Workbench 11.
If I should use Workbench, can anybody give a good link where I can find tutorials on performing FEA on viscoelastic dampers.

Are you doing a harmonic frequency response on this damper? ANSYS standard or workbench are both capable of doing this kind of anlysis, with Workbench probably being easier to use.
 
I would be starting off with a harmonic analysis, then would do it for random frequency responses. If u know any tutorials regarding viscoelastic dampers in Ansys workbench, please let me know.
 
i am an undergraduate and am interested in using workbench for a viscoelastic model. Are there any tutorials on entering a command into workbench to activate the prony series to allow viscoelastic properties?
 
I'm just interested in FEA, so I figured I'd post here. Is it feasible to do FEA calculations by hand? For example, calculating stress and bending motion on a tool of uniform material and density, at certain nodes throughout the tool (for example, bending movement of a wrench as it tightens a nut onto a bolt).

I know there is software out there for this, but it's either expensive or difficult to use for such problems. Where could I learn about doing this kind of work by hand, or is it just a waste of time? I'd rather learn to solve such problems with pencil and calculator before using software.
