Can you post picture of your setup to see how your modelling problem, BC's and loads applied and so on? Also pictures of solidworks simulation? Might be some contact definition related issue but need more information to point you towards solution.

Read note provided under-API 6X-4.1 Failure modes para 4.1-Application. The buckling failure mode is outside the scope of the API 6X but can be evaluated using the ASME BPVC since the API 6X requirements are similar to BPVC. All envisaged failure modes are need to be addressed by design...

I am not well conversant with drill-through equipment and standards associated with it. Below is just my code interpretation. API 6X has similar requirements as in ASME BPVC Section VIII Div-2 Part 5. Refer scope section of API 16A and components to which it is applicable- ram blowout...

Check this thread-thread794-491477 and my references at the last post.

Check User defined result=>ENFOVECTORS and FVECTORS.

IMO for analysis purpose keep the filler material elastic since it will be in "compressed" state assuming the upper half and lower half with seal slots are pressed against each other and also assuming filler material is not supposed to be pressure containing. I would either leave out the...

ASME - ANSI B106.1M - Design of Transmission Shafting was used for shaft design earlier but is now withdrawn. But you can anyway use for reference purpose for 'transmission shafts' only. ASME BTH and B106.1 are totally two different standards addressing totally different components. For...

Are you using Autodyn? Might be Autodyn only supports reduced integration. Please check the Autodyn help documentation/User Manual/guide. Sorry. Currently, I have no access to Ansys. May be you can play with the stiffness in the Flanagan Belytschko damping, mesh refinement in critical area and...

Check this article then. Specifically see figure of solid bolt contacts. For beam bolts I agree, contact between bolt and hole is not defined. But how do you transmit pre-tension between flanges(clamping parts), if there is no contact between upper flange and lower flange of bolted joint...

No. This is not implied in my response.We still use elastic perfect plastic model for structural as well as pressurised component. That is why I wrote I would argue about EPP model. Rather structural/energy industry standards recommend to use this model as AS5001.6 suggested. The EPP model...

1-Constrain edge translation in vertical axis only. (If required)With additional constraint of one of the corner in both lateral direction to avoid rigid body motion. All rotations free. 2-Another "complex" but more accurate approach would be to define support surface below plate edges and...

This Link might be useful for understanding bolt modelling. There are lot of articles online such as this which can be useful to understand bolt modelling.

Only for hex elements- Model=>geometry=>details of "geometry"=>element control=>set to Manual Then select the solids under geometry for which you want to use full integration element=>brick integration scheme=> full For shell elements, need to insert APDL command snippet under surfaces...

Yes but this will be still insignificant/negligible compared to bending moments in/out padeye plane due to sling angles with vertical. My question is how sling attached to shackle is able to apply "significant" torque about vertical axis? Unless you use bar passing through padeye hole for...

To your both questions, one single answer could be -mesh convergence study. Simple steps-perform mesh with size 1 and note down peak stress/strain/any other result parameter to control and change the sizes to lower size 0 or higher size 2. Do this until 3 consecutive sizes have result parameter...

Its confusing. How practically flanges pass through each other like ghost? You need to define contact between flanges(assuming you mean clamping parts), between bolt shank and bolt hole and between bolt head and part under bolt head. Without this, all parts fly or pass through each other. You...

1) Would adding preload to this joint add in the overall joint stiffness? Yes. But how the socket screw is holding the part A and B? I can see that there is taping in part A and most probably the screw will be hand tightened/light torqued to some torque(Mostly < 67% or even 50% of Sy if purpose...

Try solving your beam problem in general purpose FEA software like Ansys/abaqus and compare the results with "AutoFEA". See what results you are getting at each of the axis direction.

Check whether you can create user defined system and use that to post process the results. You can contact customer support instead of trying to guess yourself//us to better understand this. Genaeally all softwares provide stress in Cartesian or User defined co-ordinate stress.

Bipan If your organization have purchased Ansys license, you can register on customer portal and get the required resources for training. If not, you can install student license and then lot of youtube videos are available and by Ansys youtube channel also to start...
