Thanks for the comments, The loading is 5g in longitudinal direction, the high stress is not unrealistic as it distributes over a wide span with a peak at the hole edge elements. the bolt joint modeled using RBE3 element (if you are familiar with NASTRAN) and the element does not create...
i have a skid made of a plate with a certain thickness and modeled with shell elements (no solid element used in the model). The question is do I need to apply the thickness of the washer to the thickness of plate at bolted connections to improve the bearing strength of the skid at bolt holes...
A common practice for calculating the buckling strength of a part is to apply a unit load and check for Eigenvalue which is the critical buckling factor (the part would buckle at a load of calculated eigenvalue times the unit applied load) but the question is when in a structure there are...
I do have a complex structure modeled using shell element (FEMAP with NX-NASTRAN) under a combination of loads in different directions. it is required to have the stresses be less than 80% of the buckling strength of the structure. The question is how to check the buckling strength of the...
Anyone familiar with FEMAP (using NX Nastran as the solver) knows how to use the software to calculate the weight of structure and use it as the input load. (The material and associated density were specified).
Please someone advise on how to create a printable report from input/output data in FEMAP using NX Nastran solver? this option is as easy as a click in ALGOR.
Dear Sam,
i should admire ALGOR for the excellent software and the ease of work with it, but i believe it is not a software related issue i am trying to solve a concept in my model. ALGOR already offered me to send the model to be analyized (thanks a lot for the offer again) but as i mentioned...
Thanks for the comments PROST,
Checking the model as you mentioned for a simple structure is very easy but my problem is that the structure consist of about 150 parts (all same material though) and weight about 20,000 lbs. i checked the model in CAD for any interference of the parts and so far...
Thanks Mr. Borowski,
to answer to your questions, yes I auto-mesh the model however i refined mesh in the area of interest. The mesher did not indicate any problem nor warnings. This is a static stress with linear material problem. the parts assumed to be in full contact (bonded). I tried having...
I do have a large assembly where initially i used solid element to mesh. Recently I end up using shell elements (model has over 100 parts/plates on it) but I get different error messages such as flexibility matrix singular or excessive deflection. Could someone please advise on how to check my...
