dear udayagiri sai babu,
please note, that a mailing list is no replacement for reading
textbooks, studying the literature, and asking advisors and/or
colleagues for help. before asking about "is there a command",
wouldn't it be great if you not only get a number but also
understood how a property is computed?

have a look for material about equations of state and figure it
out for yourself. you will be rewarded by knowledge and not
just a numbers.

ps.: you could start looking here, for example:

The fix deform command will stretch a simulation box in various ways, from
which stresses and strains can be measured.
