    FEA of a complex injection molded part with an orthotropic material?

    Thanks so much for all the input! At this point I'm pushing to do some testing on actual parts to see how orthotropic the material really is. I'm hoping that the way the test coupons were shot in the mold, all the fibers are oriented along its length much more so than a real world part would...

    FEA of a complex injection molded part with an orthotropic material?

    I have a customer who is using a plastic with a sort of carbon fiber fill material in various injection molded parts. The material is well characterized and quite orthotropic (anisotropic). They want to run FEA on these parts, but I don't have experience running FE simulations on orthotropic...

    Tolerance in assemblies?

    Thanks for the advice guys. To answer your questions: JMirisola: Undersized parts is a concern as a result of undersized models and doing a blanket +/- .XX" tolerance. In the past I have noticed parts of a given weldment being undersized, but the over all dimensions always came out OK...

    Custom Thread Basics

    "I suspect I can find the answer in the machinery handbook, however, I am off site and cannot get to one easily. (Is there an online version?)" As I stated, I'm off site and can't get to one easily/quickly. I'm kinda hoping this is a fairly simple answer that someone here can supply...

    Custom Thread Basics

    OK, I'll start this off with an apology, as I know this is a basic issue. I will also state that I have searched, both here and google with no real success. I suspect I can find the answer in the machinery handbook, however, I am off site and cannot get to one easily. (Is there an online...
