RE: Virtual Work

[Subject Prev][Subject Next][Thread Prev][Thread Next]
I think virtual work is what my day has been like.  I worked all day and
have virtually nothing to show for it!


Okay, I learned about virtual work back in school before desktop FEA
programs became a commodity.  It is a shortcut way of solving
indeterminate analysis problems.  I have virtually done no virtual
analysis in the last 15 virtual years or so.

it? 
how do we use it? what is the advantage? what is the relation with
virtual 
force and virtual displacement?.
