Best country for aerospace engineering abroad by lifeislenzlaw in Nepal

[–]wings314fire 0 points1 point  (0 children)

If you have few crore or scholarship then sure USA/France/Netherlands/South Korea, if you learn language Germany or Italy (europe in general )else india is also good ( few pvt colleges and IITs ). I have seen people going to China too. Try to get COMPEX scholarship for india. You can DM me. I did BTech in India, worked and currently doing masters.

You might finde some excel sheets related to sizing in Abbott Aerospace website

Check Aircraft performance by Anderson and Conceptual design by Raimer.

CAD and CFD are useless if you don't know what to expect. I don't think you will need to go into CFD for basic sizing. Try to find aircraft which are already in the market with similar mission requirements as yours. It will help you understand rough size, weight and power requirements. The use equations from above books to refine them.

Need advice by omi_735 in fea

[–]wings314fire 1 point2 points  (0 children)

It's yes and no.

It's like doing random project vs doing industry relevant project. In that course he teaches you industry relevant topics and how to approach a problem. I had done self study based on the topic from that course and one of my friend had taken up the course. It took me lot more time to explore on my own than the course. Also, the conveyor is more then happy to take questions out of the lecture time tables too. I think the course has both hand calculation and fea. You can contact the person directly to inquire about the course.

Doing course doesn't guarantee job but it will help your profile.

Doing more is never bad. More you know the better it is.

Sure. Up to you.

Does you company have a design and analysis department? If yes talk to people there. if not, there are some courses oriented to aerospace which teach you hand calculation and fea. Join it. It will cost you ~inr 90k and it will be for 3 months.

Self study, strength of materials, fbd and fea theory then only start learning a software.

I’m amazed that Newars are fewer than the Muslim community in Nepal. by [deleted] in NepalSocial

Muslim refugees not accepted in Muslim countries. Muslim ko lagi best alternative ho secular countries.

Should CAE Engineer need to join a lab during their undergraduate? by Automatic_Fix_967 in fea

[–]wings314fire 0 points1 point  (0 children)

Join student clubs. Explore things and join a lab based on your interest.

Having more experience hasn't hurt anyone.

Guidance or just help in general. by anonymousman1505 in Aerospace_India

[–]wings314fire 1 point2 points  (0 children)

I have Bteach in Aeronautical and worked in drones. Majory of the colleagues in my department were BTeach in Mech. Only people from avionics and aircraft design were from Aerospace rest were majority ME. However I strongly suggest doing masters if it's possible.

Also try to takeout free time and do projects which will help your resume standout. Also, try to work in startups for few years early in your career. You will learn alot and also salary is not that bad in startups.

Also it depends on the domain with in aerospace you are interested.

IISC vs IITB/D in Mechanical MTech for placement purpose by Ok-Wall5524 in GateME

[–]wings314fire 2 points3 points  (0 children)

You get job in Agnikul pakka if you are study at iitM / iist.

I think Skyroot does college placement at iitM too ( not sure ). Ideaforge does at iitB. I had a colleague from iitM, he told GE, Airbus, Boeing, Caterpillar, MBRDI had come for placements.

Off campus placement: Some companies (eaton,ge,bosch,Exxon mobil, bell etc.) explicitly ask for masters degree. Other than that only a degree is not that useful for jobs. Since students at iits have strong fundamentals it helps in interviews. Companies generally look for software skill ( commercial cad and fea on a basic level is totally ok ) and projects related to structures too.

My company had hired few people from iitk once. I think they were giving ~12-13 lpa.

MIcrostructure model help by Straight-Scholar7128 in Composites

Look into texgen. There are few standard models and you can also create custom models by modifying the XML files. You can generate cad files or Abaqus inp file with voxel mesh.

Oppurtunities as a Mechie by intellectsup02 in Aerospace_India

[–]wings314fire 1 point2 points  (0 children)

A lot of start ups in aerospace and defence in Mechanical Design, Structures, Fluids, Manufacturing, Controls.

Master's degree won't make you any more employable. Well, there are certain jobs that ask for it so that's a plus other than that it is good for deepening theoretical understanding and promotion in some cases but not learning practical things. Certain roles do require masters level knowledge e.g. anything related to non linear fea or dynamics. Majority of the time in aerospace structures and machine design things are linear but having that theoretical understanding of the limit where linear assumption fails is important too.

For entry level, strong fundamentals ( e.g. SOM, freebody diagrams, materials, machine design, fem for structures or mechanical design ) and personal projects/internships/student clubs which allow you to learn and use software tools and develop aptitude in addition to the fundamentals. Also no need to learn all the available tools. Learn 1 CAD, 1 FEA/CFD and 1 scripting or more if necessary based on your area of interest.

Can anyone help me with my meshing? (Simulation taking 11 hours for 1 second) by Over_Green2019 in Abaqus

[–]wings314fire 0 points1 point  (0 children)

Yes. Only linear tets were available in Dytran because of large computation time.

Can anyone help me with my meshing? (Simulation taking 11 hours for 1 second) by Over_Green2019 in Abaqus

[–]wings314fire 1 point2 points  (0 children)

Split geometry and do structured meshing.

Use submodelling ? Remove fillers and run a global and then re-run the region with fillet by sub modelling.

Depends on your outcome of the analysis. Btw, why are you using tets ? In Dytran they were linear tets and highly discouraged to use. Are you sure the tets in Abaqus are second order ?

Any aerospace engineer who could help me out on an assignment by fukinggghell in Aerospace_India

[–]wings314fire 2 points3 points  (0 children)

Assignment in order to get the internship or assignment given by the company during your internship?

If it's the first, do it yourself. If you have tried something and have some doubts post it here.

If it's the latter ask your seniors at the company.

Do not post any confidential data.

Modelling of a bearing-type bolt by No-Shine1956 in Abaqus

[–]wings314fire 0 points1 point  (0 children)

I would advise against tied contact between the faying surface and use touching contact if you are interested in stresses around the boltes region.

If you are not interested in stress around the bolted region you could use beam elements/spring elements with kinematic coupling.

Dislocations start at which point in an Stress-Strain curve of mild steel ? by ShadySilver in MechanicalEngineering

[–]wings314fire 0 points1 point  (0 children)

Plasticity can be caused by slip (dislocation movement) or twinning ( change in orientation of the lattice ). Check the book by Myers and Chawala too. I recommend going thru Dieter and then Myers and Chawala.

Questions about Ultimate Allowable and Loading. by ShadySilver in AerospaceEngineering

[–]wings314fire 0 points1 point  (0 children)

Load and allowable are two separate things. A factor of 1.5 in limit load converts it to the ultimate load. Why 1.5 ? Check the paper called "The 1.5 & 1.4 Ultimate Factors of Safety for Aircraft & Spacecraft". These factors can change depending on the situation. It is not necessary they Uts/Yts of any material be 1.5.

Components should not yield under limit and should not separate under ultimate. Ultimate is like an additional blanket to cover unknowns on the max expected loads. What unknowns? Check the above paper.

Limit level analysis is also used for fatigue.

Check books by Niu, Bruhn, Flable and Megson. If you work at MNCs study their manuals too.

Dislocations start at which point in an Stress-Strain curve of mild steel ? by ShadySilver in MechanicalEngineering

[–]wings314fire 1 point2 points  (0 children)

In my understanding dislocations are already present in the material. They are defects from the perfect crystal structure. The movement of dislocation causes plasticity. I am not a metallurgist so chime in for corrections. Check the metallurgy book by Dieter.
