    Costs of Various Metals

    I am looking for a comprehensive list of costs of different metals such as steels, Al etc for variety of shapes and sizes. One way is to call the vendors but I need comprehensive and LOT of information. I realise that the rates keep changing but I just need ball-park figues. I tried googling but...

    Anyone familiar with COSTIMATOR ?

    Anybody familiar with this cost estimation software: COSTIMATOR. I did a search on eng-tips but did not find any references. Please let me know if anyone has used it. Thanks Ahad

    Ph.D. in Project Management

    Thanks all for your input. So a Master's degree may be a plus but Ph.D. is more of a PR value. I do agree that experience would be a more preferrable asset than degrees. But do these opinions only stand for the Project Management Specialization or the field of Eng Management in general. What if...

    Ph.D. in Project Management

    I have a masters degree in mechanical engineering and 4 yrs experience working with force transducers. I am thinking of getting my Ph.D. (Part-Time) in Engineering Management with specialization in Project Management. I wanted to know if it is too early to get a degree in Project Management...

    Solving System of Linear Equations

    Is there a simple command in Fortran for solving system of linear equations. Like matlab has x = A\B to solve Ax=B. Thanks Ahad

    BOLTED CONSTRAINT

    Thanks rob768 & johnhors. johnhors, is case 1 usable if the surface is sandwiched between two plates using bolts. Thanks Ahad

    BOLTED CONSTRAINT

    What is the best way to simulate a bolted constraint. Say it is loaded with 3 forces and 3 moments along each axis. The two ways I can think of are 1. If there are 6 bolts on a bolt-circle of dia 6". Then I would constrain a "ring" with outer dia 6.5" and inner dia 5.5" (Depending on the...

    FEA course notes

    lukeme, Try typing in "introduction to FEA" or "stiffness matrix" etc in google you should come up with hundreds of websites of course notes. Ahad

    Array Declaration

    Thanks George, The answer to your question "...but do you need an array to hold the results of the location of the "1"? is Yes. That is exactly what I need. ahad

    Array Declaration

    Thanks HTH, I am going through the information. The reason i need this functionality is that I have a matrix D=(1,1,1,0,0,0,1,1,0,0,1,0) which I have stated in my program as REAL, DIMENSION(1,12):: D D = RESHAPE((/1,1,1,0,0,0,1,1,0,0,1,0/),(/1,12/)) I want a matrix F such that it tells me the...

    Array Declaration

    Hi, I am new to Fortran and using Compaq visual fortran. I tried looking up on google but couldn't resolve ths problem. I need to declare a matrix but the dimensions of this will not be knwon till the program gets to the executable part of the code. From the executable part i get a value for...

    Commerical FEA Software Code

    Thank you all. This is what I understood from your comments: Since Matlab does not interact with the hardware like other low-level languages it takes longer to run the code. And when the dofs involved is large that makes it even more painful. Hope I got it right. Thanks ahad

    Commerical FEA Software Code

    This is just a curiosity question. Are there any commerical FEA software that have their code written in mathematical software like Matlab, Mathmatica or Maple? I am guessing the answer is "NO". Can anyone tell me why? Thanks

    mesh refinements...

    Try adding a small radius at the foot and see if the solution converges.

    Load

    I agree with JStephen. See how much stress your gravity load alone gives and compare it with the stress obtained by applied full-scale load. Also see how much your part/assembly weights and how it is supported. ahad

    Stress analysis

    Vikrameng, The software should come with some sort of training manual or help documentation. If you don't have those then try online to find a tutorial. Or send one of those "spam" emails to your friends asking if they have a tutorial :). Having said that I should add that it is always good to...

    how pro/e intrerprets bearing loads

    Sarita, Is the rod bolted to another surface with the help of bolts going through these holes ?

    Reporting Max Stress

    corus, I plotted the stresses and I do not see any abnormal spikes. And also I ran another "MPA" with higher order polynomial (7) the convergence % has reduced since the last run which used a polynomial order of 6. I guess this shows that there is no singularity. I have six loads and below are...

    Reporting Max Stress

    chris9, My model has all solid elements but the load-case is such that one of the sharp corners of a rectangular beam is seeing this high stress due to singularity. To be more precise the high stress is on the curve that forms as a result of two radii intersecting at the foot of a rectangular...
