CE 205 : FINITE ELEMENT METHOD (3:0)

Timing: Tu Thu 3:30 pm         Venue: Civil Annex Room 205

Description

CE 205 is a graduate-level core course which provides an introduction to the finite element method. While the primary focus of the course is the application of FE to solid and structural mechanics, the mathematical foundations of the finite element method will also be visited. A background graduate-level solid mechanics course (CE 204 / ME 242 or equivalent) is recommended. Please email me if you have any questions.
