    textbook on vibrations

    Can you provide me with title and author of a few good textbooks on Vibrations? Thanks...

    Is CRS1018 same as SPCC?

    All, Is calling out SPCC on my drawing same as CRS1018? They are both cold rolled steel right? So is CRS 1018 more specific compared to SPCC? Could some one help me to exactly differentiate between these material call outs? Thanks in advance....

    time constant-transient heat transfer

    From a plot of temp vs time how can I calculate the time constant? Is that the time when the slope goes to 0 or the temp reaches steady state? Thanks,

    Thermal properties-Conductive Epoxies

    All, I am looking for complete thermal properties for electrically conductive epoxies. These properties are hard to come by (atleast from what i have seen online) and so I will take what I get and not worry too much about minor changes in components. Thanks in advance....

    Typical heat generation-image sensors

    Hi all, I am looking for some info on typical heat generated by image sensors. Can any one give me an idea or point me to an appropriate location on the www? Thanks,

    Watertightness in mesh

    Hi All, I am having problems with a complicated solid model that I am trying to automesh. It is a big assembly and one of the parts gets flagged as it was not successfully surface meshed. However this part is able to solid mesh without any hassles. However a part that did not get flagged...

    Equivalent beams

    Hi all, I have a basic question from strength of materials. If I have a beam whose cross section is a trapezium, how would I get an equivalent beam whose csa is a rectangle? Would the two beams be equated for max. stress, or just moment of inertia ? Thanks

    Ejector pins

    Hi All, I believe I am asking this question in the right forum. I am wondering if it is ok to add an ejector pin location on a cantilever like section of a plastic part. I am adding this as I would like to ensure the part falls out of the mold, however I am not sure if that ejector pin itself...

    Model statistics-node count

    Hi All, How can I cound the total number of nodes/elements in my model before I run it? I have a meshed model which I would like to inquire "model statistics" on, but this option can be viewed only in the results pane. I dont have any results as I have not run the model yet... Thanks

    Transient stress (modal superposition)

    I am trying to recover stresses for upto 20modes. Transient stress does not seem to have an option for inertia loading. My load is an impact load. When I enter a load curve (f-t)and ask it to recover modes from previous run, it calculates 0 stresses. I went through all the modes, and it looks...

    Constructing a plane

    I have been using SW regularly since ver 2003. However I find myself unable to do something very basic. I am trying to construct a plane with three points (x,y,z) whose coordinates I know. The options I tried are: * Tried to create a plane (but forces me to pick points that exist in the model)...

    Inserting a meshed part into a model

    Hi All, Anyone knows how I can import or include a meshed part into another fea model? Both the meshes are built using FEMPRO/SD. I am currently using ver19. It would save me a lot of time to include a few parts that I have already meshed before into a new model. Thanks

    Non magnetic Stainless Steel

    All, I am trying to locate a non magnetic stainless from the austenitic series. I tried a sample of 304 but even that was slightly magnetic. For my application unfortunately I cannot use Al or Brass. From what I looked online, I read that even austenitic series get back a little magnetism after...

    "Program Exception:Access violation" Error in Algor

    Hi All, Anybody know the reason for an error with an MES analysis that looks like this in the ALGOR window where we track timesteps and covergence ? forrtl: severe (157): Program Exception - access violation Image PC Routine Line Source...

    Dimensioning drafted plastic parts

    Hi all, Is there a recommended way to call out dimensions on plastic parts that have a draft on them? Like for instance distance between two surface that are drafted. The way I have done is to call it out from the point where my draft starts (neutral plane)but since the angle is so small, it is...

    GD&T (Perpendicularity/Surface profile)

    Does it make sense to call out a perpendicularity and surface profile for the same feature w.r.t the same datum? Doesnt one serve to tighten/negate the other? If my understanding is right, if I have a 3d curved surface whose every point must be located within parallel planes (tolerance zone)...

    Tolerances on plastic parts

    Hi, I have very recently started working on plastic parts design. I would like to know what is a typical error in perpendicularity for a molded part. I am just trying to get an estimate and an educated guess from experts out there would really help. Thanks
