    Did I Ruin My Career?

    A big thanks to Fasteddie82, FastMouse, IRstuff and spongebob007 for those responses. Also, an apology to TheTick, I realize that I should not have made the remark that I did, I was just slightly perturbed some of the more negative responses and acted out. FastMouse, I especially appreciate...

    Did I Ruin My Career?

    Maybe I should explain my idea of picky, it is not massive salary + perks + time off + hot secretary. I simply want to work for a company that has interesting things to do (can't go too wrong with engineering in that aspect) and respect for their employees. If I start out at $30k a year because...

    Did I Ruin My Career?

    Thanks again, I guess just to clarify, I really do desire to settle down in my home city, I really love it here and with my first job I did intend to make a career of it before things went south. Granted, I didn't tell the entire story of what happened at my first job but if you think that I...

    Did I Ruin My Career?

    Thanks to some of you for the good advice. Thanks even to some of you for the abuse, it gives me a better idea of what goes on in the heads of the older engineering crowd when my smiling face plops down in the interview chair in front of them. I assure all of you that I have never used YOLO in a...

    Did I Ruin My Career?

    So my story: I graduated with a BSME about 4 years ago during the worst part of the slump into the "great resession". At this time I was offered a job with a small company who payed me $40k per year, which I took. At the time I didn't care about the pitiful salary because I wanted to gain...

    Shell vs. CBend vs. CBar

    It would make sense to me that the smaller your wall thickness to diameter ratio is the worse your results are going to be. 1D elements would not account for walls warping and changing shape under load. Like how with 1D beam theory as a guide I could design a pretty stiff column with just...

    MESHING SURFACES...

    My preferred method for doing this is to project a curve onto the bottom surface where it joins with the top. Then mesh both curves with the same number and distribution of nodes. Then use a merge or equivalent command to make all the matching nodes the same node.

    Resonance Fixture. Crazy Idea?

    It is a sine dwell at a single frequency, there is not a broad spectrum of frequencies. IR, I guess I am not fully following your point. If we design the resonance and shoot for the ramp up rather than the peak of the resonance. Say assuming a Q of 4 I could just multiply the weight of the...

    Resonance Fixture. Crazy Idea?

    We have a spec for a sine dwell on a project that I am working on. The level is higher than we can do at our local test facility which is where we would prefer to test. So my question is... Is it unheard of to design a fixture that will resonate at or near the test frequency so that you can...

    Meaning of Amplitude Change and Frequency Shift after Random Vib

    From my experience you can expect the frequency shifts to align as long as the part is designed to withstand the loading, amplitude shifts on the other hand are much harder to control and to explain when they occur. Most customers will give us a 10% frequency shift spec with no amplitude shift...

    Software for test-analysis correlation

    I attached a python module that I created to do most of those things. It works really well with the python(x,y) development environment (which can be downloaded for free at http://www.pythonxy.com/) It can import NASTRAN .csv files that are generated with the XYDATAGENERATE command as well as...

    Help with design of computer input devices

    VE1BLL, do you remember the name of the OEM? I found 2 OEM suppliers but did not see one with that capability.

    Help with design of computer input devices

    I am not an electrical engineer (although I did take a digital logic class) so please excuse the amateurishness of my questions. I think that I may have found a niche market for a specialized usb keypad input device for a computer. The questions I have pertain to how exactly I would go about...

    Bearing load augmented due to a shim

    It looks like he is assuming that the pin is press fit. Otherwise I think that the deflection of the pin and the slop in the holes would cause the inner lip of the loaded flanges to carry most of the load. A press fit would make the load distributions make sense. It could also be the reason...

    Need Perspective

    Thank you all for your help. I will keep all of your suggestions in mind. I have firmly decided that I to continue looking for something new.

    Need Perspective

    I am living just North of Denver in Colorado. I guess I should also mention that the job is in a field that I would really like to continue to work in. Would quitting hurt or help my chances of finding something else in the same field?

    Need Perspective

    So, I have all but decided to leave my current job and have been actively looking for a new one. Since this is my first job out of college and I have no other engineering job experiences to compare with I figured that some of the more experienced Engineers on this board could give me some...

    Plate element models and stress concentrations

    Yes, it is a hollow duct of sorts, more specifically a waveguide. With a more or less rectangular cross section. I would show a longitudinal cross section but I think that my boss would not like that much due to the propriety of this part. The purpose of the FEM is to ensure survival under...

    Plate element models and stress concentrations

    Here is a good example of what I am concerned with. http://files.engineering.com/getfile.aspx?folder=63f5dbc8-9ea9-4243-8446-b288e4c79dc9&file=Plate_Stress.BMP

    Plate element models and stress concentrations

    I know that there is a stress concentration due to sharp corners in solid models, but does the same hold true for plate models? Also, because there is no way to add fillets to a plate model is there a way to correct for this concentration? My supervising engineer tells me that we can just...
