2. Team Exercises Group 1:Team Lip
Examine the influence of changing the lip length or lip geometry on the elastic buckling (Mcr), and (if time) the DSM strength – share then report
Group 2: Team Flange
Examine the influence of changing the flange width or geometry on the elastic buckling (Mcr), and (if time) the DSM strength – share then report
Group 3: Team Supports
Examine the influence of adding springs or supports at different appropriate locations in the section on the elastic buckling (Mcr) and (if time) the DSM strength – share then report
Group 4: Make that Z a C
Take the same Z geometry and make it into a C-section with 90 deg. lips. Study the impact on Mcr, Pcr and DSM strength (if time available) – share then report
