Dear Kishore,
Tetrapeptides to hexapeptides are shown to form beta sheets. In fact, these peptides make the amyloid fibrils which are formed of beta sheets. But I'm not sure whether a tripeptide will make beta sheet or not. You might find the following reference useful:

There are ways where you can design peptides which should form beta sheet. For that you might find the following references useful:

thank You Jogender Singh .i hope i may be able to figure out the good idea from this.
Hello Kishore,
Surely all polypeptides (including di and tripeptides) can form beta sheets under appropriate conditions as also noted by Dobson. Here is a reference which you may be interested in
Street, A. G., & Mayo, S. L. (1999). Intrinsic β-sheet propensities result from van der Waals interactions between side chains and the local backbone. Proceedings of the National Academy of Sciences of the United States of America, 96(16), 9074-9076.

so can i create the beta sheet just by changing the solvent condition and i want to know exactly at what temperature and solvent condition this is possible
?
