A pedant might point out that "I read an article which I didn't understand" should be written "I read an article that I didn't understand" or "I read an article, which I didn't understand." In this case, the "which" case is appropriate, but the sentence needs a comma. In general, if there is no comma, you should be using "that", and if you are using "which", you need a comma.
