Wrinkling In Buckling And A Thin Sheet, Narayanan Menon
Patterns Around Us
Module 1: Euler Buckling
Learning Objectives:
-
What is an instability? A sudden change in behaviour in response to a small change in conditions.
-
Instabilities usually involve a change in symmetry from a more symmetric situation to a less symmetric one
-
The mechanism for an instability usually involves two competing forces (one force stabilizing the symmetric state, and the other one destabilizing it), with one suddenly winning the contest
-
These competing forces in thin objects are often the forces of compression (destabilizing force - favors buckling or wrinkling) and of bending (stabilizing force).
Understanding by data collapse, the power of using …

STEM Digital
This evaluation report synthesizes the results of evaluation activities conducted by SageFox Consulting Group of the STEM DIGITAL project led by the UMass STEM Ed Institute for its no-cost extension year, covering the period September 2013 to August 2014. The goals of the program are to facilitate the participants’ abilities to stimulate student interest in STEM careers while engaging them in ways to think critically about their environment. Participating teachers incorporated digital cameras and Analyzing Digital Images (ADI) software into lab activities focusing on environmental science. STEM DIGITAL materials focused on three strands related to (1) ozone and air quality, …
