Functionally Graded Thickness (FGT) structures are receiving increased attention for crashworthiness applications due to their outstanding energy absorption behaviour and light-weight characteristics. Accordingly, this paper evaluates the crashworthiness performance of FGT circular tube under quasi-static lateral loading. Implicit Finite Element (FE) code, ANSYS, was used to conduct numerical crush tests on the tubes. The accuracy of the FE predictions was validated using experimental test data obtained under similar boundary conditions. The crashworthiness responses of FGT tube were compared against those of a Uniform Thickness (UT) tube. The results showed that the energy absorption characteristics of FGT tube outperform the UT tube.
