The self-assembly of sphere-forming triblock copolymers confined between two thin homogeneous surfaces is investigated based on mean-field dynamic density functional theory. The morphologies deviating from the bulk sphere-forming phase are revealed, including cylinders oriented perpendicular to the surface, cylinders oriented parallel to the surface, perforated lamellae and lamellae by varying ...

Forming Limit Diagrams are useful tools for evaluation of formability in the sheet metals. In this paper the effects of yield criteria on predictions of the right and left-hand sides of forming limit diagrams (FLDs) are investigated. In prediction of FLD, Hosford 1979, “Karafillis-Boyce” (K-B) and BBC2000 anisotropy yield functions have been applied. Whereas the prediction of FLD is based on th...

Automotive sheet panel strain measurement usually involves large surface areas. For high resolution analysis, using the circle grid analysis method, several hundred elements must be measured. Existing technologies are limited to the small surface that area can be measured in one setup. As well, the (X,Y,Z) location on the part is not accurately available. This paper reports a new surface strain...

We analyze an array of linearly extended monodomain dipoles forming square and kagome lattices. We find that its phase diagram contains two distinct finite-entropy kagome ice regimes—one disordered, one algebraic—as well as a low-temperature ordered phase. In the limit of the islands almost touching, we find a staircase of corresponding entropy plateaux, which is analytically captured by a theo...
