Most common methods of password cracking are dictionary attack, pattern checking, word list substitution, brute-force attack and etc. Password cracking is a process of using computer algorithm to repeatedly guess the password until the correct password is successfully discovered.

If you do know a small detail about the password, such as the approximate number of characters, it allows you to input that as a switch to dramatically shorten cracking time. One caveat is that it will take very long to crack an archive if you know nothing about the password, and it is > 6 characters in length. It is also designed to work with CUDA so you may want to take advantage of that if you have a powerful GPU. cRARk is a freeware command-line RAR password cracking utility available for Windows, Mac and Linux.
