What is Fea: Definition and 124 Discussions

In all the Abaqus manuals I have read, it only tells me what the pre-tension option DOES, or a little bit about how it works, but what I want to know is literally which buttons to press to get to that option and how to apply it. I can't find the option anywhere in the software. Details of...

FEA MATLAB ! Please help... Hello Everyone! I need an urgent favor. I am new to MATLAB, I am in the learning stage. I am given with a coursework relating to developing a MATLAB code for 2D heat conduction of 3-noded triangular element with Finite element method. I have been given with a...

Homework Statement This is one half of a load cell I am analysing for an asignment. I have managed to calculate the stress in the beam using the equations below. I have approximated the centroid to be along the red line so that I can work out the distance for M, and then taken y or...

Does anyone know how SolidWorks calculates the stresses for this simulation. Can anyone give me an idea, is it second moment of area? y/r = m/i? Thanks Richard.

i would like to understand the arc length and line search method against Newton raphson method how the stiffness matrix updation and the general procedure is done my question is with reference to non linear fea

Hello. I'm trying to simulate a plate deflection using finite element analysis software ALGOR. Previously I made analytical calculations and I got the maximum deflection like this: (My plate is simply supported on all edges, so I used Navier's Method. Got the theory from Szilard's Theories and...

what is exact reason behind choosing basic primitive shapes for elements in FEA? Why it can't be hexagonal, pentagonal, octagonal, etc. in both cases 2D and 3D... Thanks in advance...

Hi all, I'm a beginner in FEA and got a problem regarding nodes. Can you split a line into a number of nodes using APDL script? Then a force should be applied as these nodes using F. The line is and arc. Thanks in advance Chri

in finite element analysis there is no poisson ratio for LINK ELEMENT (truss structure) just explain ?

I'm a student with no much experience with FEA and COMSOL. I'm trying to model the heat transfer from a heated cylinder. The cylinder has diameter of about 0.18 m and height of 0.36 m. The cylinder is hollow with holes from one side to the other side. I'm interesting in finding the temperature...

I am trying to compare the fluid velocity given by the closed form solution and FEA analysis for fluid flowing through a channel that is 800u long and 100u wide. I am using the equation vmax= (gradP)*(radius)^2/(4*viscosity) I got 8.4cm/s in the former compared to ~10cm/s in the latter...

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.

Hi, folks, I'm an aspiring Mechanical Engineer, & as such am very new to the subject of stress, strain, etc. I'm designing an assembly using a hi-performance polymer that has the following characteristics: Tensile Strength, 73°F 10.1 kpsi (10,100 psi) Tensile Modulus (E) 340 kpsi...

For the tension test specimen (shown below in the link) I am using Ansys Workbench to calculate the stress in the parallel portion. How could I go about checking this through manual calculations? I have been told to use beam theories for this, however I can't see how this applies as the force...

These are the one with which I am most familiar. There are others, but these are the biggies. We use ABAQUS as well as our own proprietary methods, particularly for dynamic, large strain and nonlinear FEA. ABAQUS (HKS) - for nonlinear Finite Element Analysis (FEA) www.hks.com...

Dear fellow engineers, I resently posted my resume and got several reactions good for me bla bla... Question. Which modeling sofware (Pro-E, Catia, Solidworks) and which stress analysis (FEA) program is best and most used. I like pro_E. It seems that everybody is using something else and...

I just modeled a single square plate of size 50x50 and thick 1 and applied a force on two nodes(total force is hence 100). The software i used is nastran. The force vector is shown as arrow in the image. My doubt is all the points in the plate should have the stress=100/area=100/(50*1)=2...

Hi all, I am a student of Music technology and for a project that I am working on I need to do an unusual FEA. I want to create a simulated model of the sound phenomenon that occurs when a sheet of material is deformed. As part of this I am required to a dynamic finite element analysis for...

I know that shape function is a function that will give the displacements inside an element if its displacement at all the node locations of the element are known. What is linear ,polynomial in shape functions. If i say as linear somebody else may say polynomial etc. I am not able to...

How non linear fea works. I am studying that and i can't find any material in the web which has some basics. How the Newton raphson method is used in non linear fea suppose i apply a force f on a structure after that how non linear fea works?

i have put this question in other forum also. I have understood the stiffness matrix generation for a single rectangular element as below. I consider each node having 2 translational dofs each in x and y coord system. There are 4 nodes in this rectangular plate element and hence 8 dofs...

i know that the stiffness for a line element is calculated as fl/ae where a is known as area and l is the length,f is the force applied and e is the youngs modulus. How the stiffness of a plate element are calculated?

I just used nastran to do an fea analysis using plate elements of thickness 1.22 mm. Nastran gives two vonmises stress values for plate elements 1.plate bottom von mises stress 2.plate top von mises stress what are they?
