    Abaqus script to find centre of the circle

    Hello, Although my proficiency in Python is limited, I would greatly appreciate a simple script that can verify the edges of assembly instances and generate a central reference point. With this tool, I can easily create multiple connectors in a large assembly. Thank you very much.

    ASME Design by analysis - ELASTIC-PLASTIC STRESS ANALYSIS METHOD

    Hi there, I have another question with regard to the ASME Section 8 Dev2 PArt 5. For the calculation of protection against collapse, we have three methods: Elastic stress; Limit load, and Elastic-plastic stress. Since I have good experience with nonlinear FEA I would like to perform...

    ASME SEC. VIII, DIV. 2 – PART 5 - TRENING

    Hi there, I am a CAE engineer and have been specializing in FEA for the past 10 years now. While I can get around analysis quite well I have not used it a lot in alignment with particular standards. I now have the opportunity to work in pressure vessel design and analysis and would like some...

    Run BLDC form the 220V grid

    Hi! I am trying to use the BLDC motor in home appliances and I wondering if there is a simple way of running a BLDC motor (1.5kW) from a 220V AC grid. To my limited knowledge, I would need an AC-DC converter and an ESC to create the three-phase for the BLDC. While ESCs are rather affordable...

    Carbon fiber threaded inserts

    Hi there, does anyone have any good proposal for the carbon fiber threaded inserts. I found the ones on the link below, but they are hard do get in my country. https://www.mcmaster.com/square-tube-inserts/press-fit-threaded-inserts-for-composites/ Thnaks, Uroš

    Carbon fiber fuel tank

    Hi There, we are developing the carbon fiber fuel tank for vehicle application. We are worried about the chemical resistance of the CF tank. The tank would be made for the USA market, where gasoline can contain up to 15% of ethanol. I have come across some articles that the presence of ethanol...

    Multiple Y-fitting to split the flow

    Hi there, I would like and opinion what would be the easiest way to split the flow coming form a single pump (160 m3/H) and even flow in 8 pipes (each 20 m3/h). the split into smaller pipes is needed for the water treatment that can only be made on the 20m3/h flow and we would like to avoid...

    Bolting of the follow sections

    Hi there, could someone provide some general guidance on how to bolt together multiple hollow sections? I am using only rectangular sections. Also, I attached the figure below and am interested in which of the two ways is the "correct" one, when it comes to connecting two rectangular sections...

    Abaqus for structural analysis

    Hi there, I am starting to use Abaqus for steel structure analysis and while I am quite skilled in Abaqus I find it a bit confusing and time-consuming to assign all the loads and load combinations considering certain design codes like EUROCODE. SO my question is: Does anyone knows of any Python...

    From mechanical to structural engineering

    Hi there, I am a mechanical engineer and would like to get more involved with structural analysis of steel structures. I have many years of experience in FEM and stress analysis using Abaqus and would like to use this knowledge in civil and structural engineering. I have worked mainly in the...

    Difference between Moulding shrinkage and thermal expansion

    Hi there, I am trying to make the simulation of injection molding. I use ABS plastics. After cooling down the "warpage" which to my knowledge should be the final deformation of the part after it has cooled to room temperature, is about 1%. This to me is rather strange since the mold shrinkage...

    Landing gear load calculation

    Hi there, I am working on the project regarding the landing gear structural analysis. I have gone through the FAR part 25 for the ground loads. The load cases seem quite reasonable, the only problem is that I am not sure how these should be calculated for a given aircraft. The part I find...
