Elastic strips [PDF]

open access: yes, 2010
Motivated by the problem of finding an explicit description of a developable narrow Moebius strip of minimal bending energy, which was first formulated by M. Sadowsky in 1930, we will develop the theory of elastic strips. Recently E.L.

Uniform fatigue damage tolerance assessment for additively manufactured and cast Al-Si alloys: size and mean stress effects

open access: yesAdditive Manufacturing Letters, 2022
The near-net-shape manufacturing in additive manufactured and cast of Al-Si alloys results in a heterogeneous solidification and cooling of the parts, leading to significant gradients in microstructural and defect features as well as deformation behavior.

Curve straightening and a minimax argument for closed elastic curves

open access: yesTopology, 1985
THE RESULTS obtained here have to do with the following problem. Imagine the ends of a straight length of springy wire are joined together smoothly and the wire is held in some configuration described by an immersion y of the circle into the plane or into R3.
