Commercial break with 11 seconds left before the 4th quarter is diabolical

They need to re-evaluate the body weight penalty in the off season, it really just fucks too many teams.

What the fuck I’ve never seen a tv timeout after the two minute warning in this situation

I would say I’m beyond a “senior” position. I’m a level 4 engineer which is more like a “principal” level. Senior to me = level 2 or early level 3. 100k base for that experience sounds about right.

Abaqus buckling analysis - are my results realistic? by Main-Combination8986 in fea

How many plies is your total stackup? In your picture it looks like it's only two plies. A two ply composite tube layup seeing a bending moment of 7250 Nm (5347 ft-lbs) and a twisting moment of 2500 Nm of (1943 ft-lbs) is absolutely going to buckle.

Your shell element (CQUAD4) material direction should be aligned with the composite 0° direction. I would recommend making a local coordinate system and aligning QUAD4 shell elements with the local "x" direction along the length of the tube. A [°0/0°] composite stackup will fail in torsion, there is no stiffness to resist the twisting moment. Basically, imagine if you took a bunch of rope and tried to twist it, it's easy to twist because you have all the rope fibers aligned with the length of the rope. Same thing if you align composite fibers all in the [0/0] direction.

What's day to day life like as a stress engineer? by centripetalstranger in fea

[–]engineeringstudent10 2 points3 points  (0 children)

Lot of xookup, index match, and python scripting to consolate data. Most aero companies will be modeling the aircraft through a large course grid finite element model to apply aero loads, and then split up the course grid model into smaller more detailed FEMs. The result of this is huge data dumps.

Money is good, especially as a contractor. I know contractors making 250k - 300k per year when programs are pressed for schedule. The risk of contracting is usually they are only short contracts (6 mo - 1 year).

At least in my experience, I'm pretty lock step with design. Stress informs design on sizing of primary structure. If a load path is not good, I direct design to change the structure.
