Symptoms of knee instability in older adults may indicate an increased risk of falling and of experiencing the various physical and psychological effects that can result from falling, according to a ...

Bacteria swim by rotating the helical, hairlike flagella that extend from their unicellular bodies. Some bacteria, including the Escherichia coli (E. coli) living in the human gut, have multiple ...

When a strut is loaded in compression it may be unable to support the applied load and fail by Buckling rather than by Plastic Deformation. The buckling process involves the primary elastic response ...

Buckling is defined as an instability leading to structural failure and is categorized by a sudden sideways deflection of one of the structural members. This can occur below the threshold that is ...

Some physicists studying elasticity filmed rubber bands at super high speed capturing the process of "dynamic buckling instability". Check out the article and the links to the movies here. Valar ...

A growing or compressed thin elastic sheet adhered to a rigid substrate can exhibit a buckling instability, forming an inward hump. Our study shows that the strip morphology depends on the delicate ...

The photographs show two tubes that have buckled and plastically deformed, a plastic buckling situation. The square section low alloy steel tube on the left has a low slenderness and the end of the ...

Buckling, the sudden loss of structural stability, is usually the stuff of engineering nightmares. But, as anyone who has ever played with a toy popper knows, buckling also releases a lot of energy.
