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...
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

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...
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...
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...
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
Is there a rule of thumb in reporting the max stress on a part on which FEA is performed using a p-element FEA softfware like pro mechanica. Sometimes the max stress occurs on a stress concentration area where the max strtess reported in the legend is very high and occurs on a point or a very...
I want to increase the swap space on my machine (windows xp prof) 3.2Ghz 1.0 Gig RAM. I came across some documentation form PTC and Microsoft telling how to change the settings but what scared me was the "messing" with the BOOTINI file. Please let me know if anyone has tried it and have been...
I have a function that takes 4 input files which are in .txt format. I created an executable with the function and when I run it in dos prompt. I get an error
"ERROR can't open file ALoad.txt."
ALoad is one of my input files in the function. I deleted the file extensions and tried again but I...
I have a beam with circular cross-section. The beam has a taper at one end. The taper-end fits into a fixture with threads and keys to restrain it from translating and rotating. In my finite element model I have fixed the taper end in all DOF. The load is applied at the other end transverse to...
I am using Pro/Mechanica 2001 structure module. I have 6 loads in my load-set. During post-processing I look at Von Mises stress for different load combinations. The results window takes about 7-10 minutes to show up. My model has 15,000 elements and I have analyzed it for 6th degree polynomial...
I am trying to write a program in Matlab for a 3-D space truss that has 3 DOF at each node translation in X, Y and Z. I am testing my program with some problems from the book "A First Course in Finite Element Method" by Daryl L. Logan. But I am not getting the right answers using my programs I...
Could anyone name a few mold flow analysis software. I know COSMOS does it. Also please suggest me some books through which I can get some introduction to mold flow analysis. Thanks.
