Physicists Spontaneous Mechanical Buckling Freestanding Graphene
2016/9/29
An international team of physicists, led by researchers at the University of Arkansas, has observed spontaneous mechanical buckling in freestanding graphene using scanning tunneling microscopy, indica...
Buckling thin disks and ribbons with non-Euclidean metrics
Local swelling properties of polymer thin film film swelling
2014/12/19
I consider the problem of a thin membrane on which a metric has been prescribed, for example by lithographically controlling the local swelling properties of a polymer thin film. While any amount of s...
Finite Element Analysis of Distortional Lateral Buckling of Continuous Composite Beams with Transverse Web Stiffeners
composite beams distortional lateral buckling transverse web stiffener U-frame action
2014/4/10
In a composite beam, transverse web stiffeners are often provided to the steel section at regular intervals along the beam span to eliminate local shear buckling as well as to reduce web distortion in...
Nonvolatile bistable all-optical switch from mechanical buckling
Nonvolatile bistable all-optical switch mechanical buckling
2015/8/10
We propose a nonvolatile all-optical bistable optomechanical switch comprising two parallel buckling waveguides. The bistability comes from mechanical buckling so the operation of the switch does not ...
