Thanks for the replies. Honestly, I don't understand the prospective about design experience. Although I enjoy analytical thinking, my only real goal is to be able to afford a house and support my family while having some work life balance. I haven't even really seen many job postings for design...
Hello I have been working for 4 years in design and it has its ups and downs. I have to find another job, though. I applied for a posting for a general ME asking for someone with experience in design, analysis, and manufacturing. The posting was rather general in nature and the company is a...
Hello,
I am working on some graduate level coursework and I am finding an off-axis Poisson ratio for a lamina is as high as 0.55 at a certain angle. I have a few references that show similar trends (Gibson's principles of composite material mechanics and this one here...
Thanks for your replies. I understand that bi-linear isotropic hardening model is a simplified model of plasticity and that a multi-linear kinematic model would be more true to life (this requires test data, which I don't have). I'm not actually interested in accuracy of the model, my question...
Hello, I am trying to experiment with nonlinear adaptive meshing and I made a quick test 2D plane stress model.
In the model, a rigid body 'tool' uses a prescribed displacement to contact a billet as a flexible body. The flexible body is fixed in the x-axis on it's sides and x/y on its base...
Hi Greg, Yes I have presented a poster session at a conference once, I also volunteered as session chair. A small accomplishment in some respects, but I am attempting to participate in professional circles.
I have taken some coursework and done some independent work in randomly oriented inclusions to lamina, so I am familiar with concepts and manipulations but composites are a topic that seem that they require lots of experience in. I would certainly consider aerospace or R&D but I have not seen...
I know this has been answered and probably the post is fading but I read this and it reminded me of one of my first projects on the job. I was asked to validate an analysis in FEA of a non-traditional geometry.
A professor from my graduate courses reminded me that maybe we could hypothetically...
Thanks for the replies. I am certainly aware that engineering knowledge is a key driver to creating a model, thats part of the reason I studied solid mechanics in grad school. I suppose I am more interested in becoming a specialist and not really interested in becoming a project manager for...
Hello,
I have been working in industry for 4 years, 3 at my current job and I feel like I do not have any ability to move up from entry level even though I only ever got positive feedback about my work quality and pace of work. I studied in a solid mechanics track for my masters degree and I...
I gave it some thought and I remembered back to the part of equilibrium equations that accounts for body forces, which of course are volumetric. So I'm kind of further in disagreement that acceleration, or EM loading, or etc, should be included because in this "cut-out" submodel because we no...
I can see the disadvantage to creating a model that controls tolerances, as 3DDave mentions, but I work in a place that is a bit of a revolving door and I had been picking up drawings on an assembly that had been kicked down the road from someone who no longer works here. After sorting through...
I am working on a submodel (in ANSYS 2021) which comes from a global model that has multiple load steps, varying temperatures, dynamic and static loads, and external data as input. After I got results, my submodel didnt seem to line up correctly when evaluating some reaction forces at key areas...
Thanks for the replies, I will look into both VSA and DCS. I'm kind of surprised that with all of the analysis and CAD software out there in the world that there aren't more widely used tolerance programs. I get the feeling that if a design requires so much precision to meet an objective then...
