A “flutter machine” is introduced for the investigation of a singular interface between the classical and reversible Hopf bifurcations that is theoretically predicted to be generic in nonconservative reversible systems with vanishing dissipation. In particular, such a singular interface exists for the Pflüger viscoelastic column moving in a resistive medium, which is proven by means of the perturbation theory of multiple eigenvalues with the Jordan block.

PhD openings at the University of California Merced

Submitted by Vazirisereshk on
job

We have openings for grad students at the University of California Merced to develop and use atomistic simulations to investigate surface and interface phenomena. Specific research focuses will depend on the applicant’s background, but may include characterization of the interactions and reactions between metallic surfaces and various industrially-relevant liquid adsorbates and exploration of the effects of coupled stresses in determining the size of the contact between nanoscale bodies.

https://doi.org/10.1088/1402-4896/aab4e2 In the 50 years that succeeded Richard Feynman’s exposition of the idea that there is "plenty of room at the bottom" for manipulating individual atoms for the synthesis and manufacturing processing of materials, the materials-by-design paradigm is being developed gradually through synergistic integration of experimental material synthesis and characterization with predictive computational modeling and optimization.

Combined experimental and numerical study on micro-cube indentation splitting test of cement paste

Submitted by shavijabranko on

Our group has recently published a paper describing a new method for micromechanical testing of cement paste. The paper was published in "Engineering Fracture Mechanics". Full paper can be accessed at:https://www.researchgate.net/publication/324510125_Combined_experimenta…
