HELLO
MY name is Hani
Mechanical engineering
my thesis is about to determin the natural frequency and mode shape
to the human femur
MY calculations was by using ANSYS PROGRAM ver.10 for FEM
now with my work i am started create my thesis subjects such as
INTRODUCTION, LITRUTURE VIEW ...etc
please any one have papers ,books, thesis, researchs, journals, any
subject may be useful in my litruture view or other
chapters.......etc that can be useful for me
and i will be grateful for all one like to help pther people
special thanks to Mr. Dave Parker for his helping about ansys program
in the last time.
You're welcome for the ANSYS help. It's been a while since I've run
ANSYS in batch mode so I hope my instructions worked. I hope I can be
of more help on this subject. I think my university did not properly
emphasize the importance of solid literature research skills. However,
I've found the ability to find relevant publications an important tool
in keeping up-to-date on the latest research in my field, and in
educating myself on new problems I encounter in my job. Luckily my
wife (a social science and marketing researcher) taught me a few key
aspects of doing a good literature review. Now I'll step off my soap-
box and give some practical tips:
A. Develop an Initial List of References
Start by developing a list that includes the Title, Author, Date, and
Keywords of papers or textbooks on your subject from several sources.
It's great if you can get full-text copies of the papers at the same
time, but getting a list of the information above is the priority at
first. There are many sources to find references. Ask peers,
professors, or consultants. Look for references used in textbooks.
Perform a web search on the subject - I use Google (Web, Print and
Scholar search tools), NASA Technical Reports Server (NTRS), and
Scitation websites.
B. Perform a Preliminary Review of the References for Relevancy
If you have full-text copies of any of the references, read the
"Introduction" and "Conclusions" to verify that they are relevant to
your problem. If you do not have access to full-text copies of the
papers, then use the websites listed above to look up abstracts and
keywords for the papers. I don't have access to a research library so
I typically have to rely on abstracts to determine if a reference is
relevant to me. Then I purchase the paper from the Linda Hall
Library.
C. References Yield More (And Better) References
This step is the key to doing a good literature review. Once you have
full-text copies of a handful of papers, read the "Background" or
"Previous Studies" sections of the papers. These sections will give
the history of previous research on the subject, and summaries of the
findings from previous publications. Identify references that are
highly relevant to your problem and add them to your list. You'll
probably also note that one or two landmark papers are referenced by
almost everyone - add these to your list. For some subjects you may
find papers that are purely a review of previous studies. These "lit
review" type papers provide a broad overview of research findings in
the field and are a gold-mine useful references. This step helps you
expand your list of references exponentially - guiding you to more and
better papers on your subject.
D. Compare Findings
This is the most tedious step, but you need to compare the findings on
a common basis to determine if there is a consensus in results among
researchers. This can be a difficult process, especially if there are
many variables under consideration, or different means of non-
dimensionalizing and correlating data. You'll then have to try to
convert results to common non-dimensional groups.
D. Identify "Poor" Publications
After reading several dozen papers you'll develop a good understanding
of the state-of-the-art experimental/analytical techniques, status of
research, important variables, consensus findings and best methods of
correlating data. Use this knowledge to identify poor papers. Some
examples: an inaccurate experimental setup or analytical technique,
limited variation in important variables, unexplained deviation of
findings from consensus of other researchers, overly simplified or
specialized geometry/boundary conditions. These papers may not
actually be "Poor", but be cautious in using them.
I hope this helps,
