My Ph.D. Defence

I am pleased to inform you that I will be defending my Ph.D. thesis, formally in mechanical engineering, at COEP, University of Pune, India, on the next Sunday (i.e. 20th September, 2009).

The title of my thesis is: "A New Approach to Computer Modeling and Analysis of Certain Fundamental Field Problems from Engineering Sciences." 

I am attaching the 10 (actually 13) pages long abstract of my thesis for your information. The thesis is based on my published articles which may be downloaded from my Web site [here].

If you would like to formally raise some questions on any part of my thesis, to be included during the official defence proceedings, then please send me a message via my profile at iMechanica and I will then let you know the email address of the Defence Committee Chairman. You could then submit your questions in complete confidence directly to the Chairman. This being the Internet, I would request you to kindly include your verification information such as your name and affiliation in your message. If this information is not completely available, I may not be able to respond to your messages. I will check messages until Saturday morning (India time).

Thanks in advance,

--Ajit

hi Dr.ajit.R.jadha

Congratulations

please juste question

I'me a student at the Departement of Civile Engineering of university of the algeria.

currently, i'm working on completing my thesis. My research area in
general is in mechanics of composite materials. My problem is that of
formulating the FEM solution to the Flexural-Torsional of laminate
composite beam having orthotropic layers.

the paper by Jaehong Lee would serve as my guideline and the
objective of my research is to do the flexural-torsional analysis by
finite element method; and i intended to use ABAQUS as an FEM tool.
now, i'm having a technical problem in attaining my objective.

in short: nobody could lend me support regarding my problem in my department.

even if you could at least help me find the moste appropriate
references about FEM or programmation with Matlab or Fortran.then i
would greatly appreciate your help.

best regards to everyone!

Thank you all: Surajit, Ramdas, Temesgen, David, Biswajit, Keng-Wit, Gopinath, err...

... Thanks a bunch. ... The reason I got so late in replying to you all was that as soon as the Defence got over, I got so busy with the followup formalities at COEP and University of Pune (its different sections). ... Finally I did get that document which is variously known as the Provisional Certificate or the Declaration of Results, and also did submit the convocation form. ... Phew! ...I still haven't got my cash reimbursements though... But by now I have lost all my followup strength (at least for the time being), and so, I intend to pick up that followup sometime later...

BTW, may I mention here that it was wonderful to see an iMechanician in the audience: Ramdas. (We didn't know each other before starting blogging here...) So, Ramdas, my special thanks go to you.

Hi,

Would like to know your name...

I have no expert knowledge in the area of your topic: FEM of orthotropic laminate composite beams.

My interest in FEM, first and foremost, lies in its fundamentals.

Conceptually, there are two ways to build FE models for entities like beams and shells/plates: (i) by filling the beam with 3D solid elements like tets/hexas, and deriving strains using the usual strain-displacement relations, or (ii) by adding an additional layer of mechanical abstraction: first assuming a model for the beam which is derived using a suitable beam theory, and then FE-discretizing this model. The difference is that in the limit of infinite elements, the FE model obtained in the second approach would converge to the beam theory---whose results wouldn't be quite the same as those suggested by, say, photoelastic or other experimental studies conducted on an actual beam. In contrast, the FE model built using the first approach would (should!) better converge to the actual stresses in the physical beams. Practical engineers, esp. Civil engineers, prefer the second approach for reasons that have more to do with computational complexity than with achieving the best possible correspondence with the physical processes in actual beams. This too can be alright, but there exists that difference. Since I am not an expert of the beam /shell theory itself---mostly Civil-specific topics---I am not familiar with the subtle points of the second approach. ...

Ditto for the laminate composites: my knowledge refers to the particulate composites, esp., those involving ceramic materials (also some metal- and polymer-matrix ones).

I suggest that you post your query in a separate thread. And, also, that you add your name and affiliation to it (and also to your iMechanica profile). BTW, how many engineering colleges/institutes/universities in Algeria award PhDs? Any rough estimate?

See you in another thread (created by you)...
