hello folk. i am task with performing bench mark test on abaqus to evaluate if it is a good switch from nastran for my company. we specialize in fem fracture mechanics work, and hear that abaqus is superior for crack grow simulation. any one have similar background or know best way to compare...
Good morning lads and salutations. i have clarifications to give on a post i made in another forum here in the structures forum. i am designing a single piece bent frame for an aircraft ground support structure (pics are simplification of actual design, assume uniform depth into sheet w...
Salutations everyone. I've got a question regarding the stress in a frame, or one could call it a beam bent 90 degrees. Assuming the beam has the dimensions shown in the image, I'm having trouble doing hand calculations at the corner indicated in the photo. Obviously there are the classical...
Good morning lads. I've noticed that oftentimes some of the senior engineers I've worked with indicate that shock analyses are inherently conservative versus reality. I understand that using modal combination, like SRSS, is conservative generally because it assumes that all modes in are phase...
Hi everyone. I know that in the aerospace industry, NASA-STD-5020 is a standard that most companies rely on. However, I have a question regarding estimating joint stiffness factors for cases where there is not enough material to develop the full frustum suggested by Shigley's approach. Does...
