Crack tip strain field around a growing crack: 2D simulation
This resource is a video, illustrating how the stress field around a crack grows with the length of the crack, presented as a contour map. It was obtained by stitching together maps of the surface temperature (amplitude) captured with an infra-red camera during cyclic loading; and the temperature amplitude is directly proportional to the amplitude of the first stress invariant (sum of principal stresses), which drives the crack forward, based on the classical Paris law. So the crack growth will

Engineering and the Human Body
The Engineering and the Human Body unit covers the broad spectrum of topics that make-up our very amazing human body. Students are introduced to the space environment and learn the major differences between the environment on Earth and that of outer space. The engineering challenges that arise because of these discrepancies are also discussed. Then, students dive into the different components that make up the human body: muscles, bones and joints, the digestive and circulatory systems, the nervo

Lights Out!
This lesson introduces the concept of electricity by asking students to imagine what their life would be like without electricity. Two main forms of electricity, static and current, are introduced. Students learn that electrons can move between atoms, leaving atoms in a charged state.

Micromechnical Biosensors and their Integration with Aptamer-based Receptor Molecules
This site is one of many on \\\\\\\"nanoHUB.org\\\\\\\" which highlights availability of on-line simulations. This particular one provides a video of a research seminar on the topic of micromechanical biosensors focusing on aptamer-based receptor molecules. The quality of the graphics in the video is not high - mainly, the smallness of the visuals makes it difficult to decipher the contents. However, the information content, as delivered and described verbally, is coherent and useful. The i

Shoes Under Pressure
Students explore the basic physics behind walking, and the design and engineering of shoes to accommodate different gaits. They are introduced to pressure, force and impulse as they relate to shoes, walking and running. Students learn about the mechanics of walking, shoe design and common gait misalignments that often lead to injury.
