It might sound absurd. When an IC fails, Is there any way to find the cause behind its failure? Eg. Failed due to overvoltage at input (inv/non inv), Failed due to overvoltage at the supply, failed due to reverse polarity at the supply pins etc.

Hi Anand,
you can try to intentionally destroy other LM324-N by overvoltage at the supply voltage pins. Your LM324-N candidates should sit in the same circuit as the damaged ones, though. Afterwards, perform careful impedance measurements between the pins. Can you see any similarities?
Another method is to open the packages of all these OPAmps and look for damages on the die. Again, can you see any similarities?
