Observation of Dislocations
Dear all,
What are the possible methods to observe dislocations in a material? Which one is better?
thank you in advance..
Rotational Abaqus Direct Cyclic Boundary Condition
Greetings,
I am attempting to model the rotation of a cylindrical bar using Abaqus 6.12 coupled with the direct cylic approach. In my model I have one end of the beam fixed while the other has a kinematic coupling constraint to a reference point that has an applied rotation of 0.1 rad.
High-temperature tensile behavior of freestanding Au thin films
In this paper, the mechanical behavior of freestanding thin sputter-deposited films of Au is studied at temperatures up to 340°C using tensile testing. Films tested at elevated temperatures exhibit a significant decrease in flow stress and stiffness. Furthermore the flow stress decreases with decreasing film thickness, contravening the usual notion that “smaller is stronger”. This behavior is attributed mainly to diffusion-facilitated grain boundary sliding.

Robust Stability at the Swallowtail Singularity
Consider the set of monic fourth-order real polynomials transformed so that the constant term is one. In the three-dimensional space of the coefficients describing this set, the domain of asymptotic stability is bounded by a surface with the Whitney umbrella singularity. The maximum of the real parts of the roots of these polynomials is globally minimized at the Swallowtail singular point of the discriminant surface of the set corresponding to a negative real root of multiplicity four.
