T&L Activities: Laboratory/Tutorial: There will be one lab/tutorial session per week for students to gain hands-on experience of using commercial finite element analysis software STRAND7 and/or ANSYS to solve one sample problem per week. There will be 12 sample problems in total to be solved using STRAND7 and/or ANSYS. These will be undertaken in groups of two and marked jointly. All students are requested to attend and perform finite element analysis for the selected example problems. All example problems carry equal marks and will only be marked off in the designated lab session. Tutorials will be organized in the Tut/Lab hours in relation to assignments.

Independent Study: Students are required to spend approximately 5 hours outside of scheduled contact time per week.
