To know in which databases you can find articles related to your subject, you can ask your professor what sources (journals, databases, etc.) s/he recommends.
You can also consult the "Journal & Conference Articles " tab in the Subject Guides produced by the librarians. You will find a list of bibliographic databases recommended for each field of engineering at Polytechnique Montréal. This list of reliable sources constitutes an excellent starting point to conduct your article search.
