University of Colorado - Intro to Aerospace Structures (ASEN 3112) - Fall 2015 Final Weeks Schedule (2) Next recitation on Friday Dec 4 combines experiment & theory: First hour: column buckling using ITLL module, to be rolled into recitation room. No electronics involved. (This used to be Lab 3, before being replaced by airplane shaker.) Load-deflection readings will be recorded and used to produce Southwell plots in a HW 10 Exercise. Second hour: one buckling problem typical of those assigned in final exam.

University of Colorado - Intro to Aerospace Structures (ASEN 3112) - Fall 2015 Last 4 Lectures We now begin 4 lectures on structural stability. Along the way we’ll encounter some of the same math tools used in structural dynamics: algebraic eigenproblems second order ODEs But the physical interpretation of solutions will be different
