Thanks Banu. Can u pls let me know when its to be done (during system testing or after that or after performance and load testing completed)?

Stress Testing:

Stress testing is subjecting a system to an unreasonable load while denying it the resources (e.g., RAM, disc, mips, interrupts) needed to process that load. The idea is to stress a system to the breaking point in order to find bugs that will make that break potentially
harmful. The system is not expected to process the overload without adequate resources, but to behave (e.g., fail) in a decent manner (e.g., not corrupting or losing data).

Stress testing is part of performance testing.

Below the baseline limits testing is load testing

Beyond the baseline limits testing is stress testing

Stress testing is done to evaluate the application's behaviour beyond normal or peak load conditions. It is basically testing the functionality of the application under high loads. Normally these are related to synchronization issues, memory leaks or race conditions etc. Some testing experts also call it as fatigue testing. Sometimes, it becomes difficult to set up a controlled environment before running the test.
