    Vibration analysis - Glass structure

    Hi, I have a dynamic analysis problem involving a steel structure and glass panes. The glass panes are looseley attached to the steel structure. They contribute mass, but not stifness. I am having a bit of trouble figuring out how to model this. The steel structure is a beam model and, for the...

    Importing a shell geometry

    I can look into creating a simpler shell element, testing it in FEMAP and exporting to here through the weekend. However my question was not related to a specific model, I just really wanted to know if importing shell element models into FEMAP was even possible. I have, and it is mentioned in...

    Importing a shell geometry

    As I mentioned above, the model is built out of surface elements... DIRECTLY. No solid elements exist in my model. For the same reason no midsurfacing is done, or is required in FEMAP. As for surface stitching, the model is already a single part; already built for FEA analysis so surfaces are...

    Importing a shell geometry

    I have, I tried using parasolid and step. The result was the same

    Importing a shell geometry

    I can, and have uploaded the image. But, and this is important I am really not looking for help solving the analysis; I have already done that. I really want to understand the functionality of importing surface models to FEMAP.... The image has lots of details, but it doesn't matter. It could...

    Importing a shell geometry

    Hi, I am trying to import a Solidworks made model to Femap. The model is built with 2D shell elements (it is already used for analysis in Solidworks Simulation). Upon importing, Femap seems to treat all the geometry as Solid, and always requesting Solid property. Even if I explode the 1...

    Bent plate angle profile behaviour ?

    According to the material I found using bent plates in stead of cold/hot formed profiles is possible in axial load but not in transversal load situations. The inherent internal stress from bending is acting in the same way as the transversal force bending stresses therby providing less resistance.

    Bondary conditions (rotation without translation)

    So PeteDB provided the right answer, I would just like to ad one note: setting the virtual plane with an angle of inclination will yield results which are a bit off due to contact in a single point. I got better results by making a virtual plane which starts off level, and progresses into the...

    Bent plate angle profile behaviour ?

    I am trying to figure out if an unequal angle steel profile (200x100) can be replaced by a bent plate of equal dimensions. I can calculate second moment of area for the shape easily and check, but production wise I have no idea how a bent plate will behave compared to profile (I assume hot or...

    Bondary conditions (rotation without translation)

    I tried putting inclined virtual plate, and keep loading vertical. But the results seem odd, and I am uncertain if that is the correct way to do the analysis. Although maybe I can apply rotating boundary condition and put an aligned virtual plate under it. I will try and be back when I have...

    Bondary conditions (rotation without translation)

    I am relatively new to solidworks simulation so maybe I am asking something quite obvious but any help would be appreciated. The model I am working on can be seen in attached image. I am trying to do a linear analysis, taking into account uneven supports. Load is continuous, but indicated...

    Bearing/Bushing Design

    Any pointers...? I am sorry for bumping the thread but I would really appreciate any pointer on the actual stress estimate...

    Bearing/Bushing Design

    OK, a more detailed image is attached including static calc. I used support centres to determine reactive forces, and calculated pressure distributed on bearing surface. I know this is a gross aproximation but I don't know if it is to great. Anyway max. force 9900kN, distributed yield...

    Casting - Primer

    Well the items in question are rather large. something along the lines of cubic meter and over a ton in weight. They are also stainless, does stainless even require shop priming. Anyway whaterver is the simplest solution

    Casting - Primer

    I have a question regarding primer painting. We are getting a casting/machining order from a company, followed by transport to another location for assembly. All the non-machined surfaces can be painted for corrosion protection, but I'm not certain what to do about machined surfaces. Should a...
