Axis-by-Axis Stress Minimization [chapter]

Yehuda Koren, David Harel
2004 Lecture Notes in Computer Science  
Unlike prior stress-minimization algorithms, our algorithm is suitable for a one-dimensional layout, where one axis of the drawing is already given and an additional axis needs to be computed.  ...  This 1-D drawing capability of the algorithm is a consequence of replacing the traditional node-by-node optimization with a more global axis-by-axis optimization.  ...  For the rest of this paper, we explore axis-by-axis stress minimization. Hence, we assume x to be an 1-D layout, i.e., x = (x 1 , . . . , x n ) ∈ R n .  ...

Stress State Required for Pyramidal Dislocation Movement in Zinc

A tension or compression stress in such a direction that basal slip is minimized can produce second order pyramidal slip bands in zinc single crystals.  ...  However, dislocation velocity at a given stress is sensitive to temperature and the very small dislocation velocity at low temperatures has lead to an erroneous estimate of a "starting stress" for pyramidal  ...  slip band to its end by the duration of the stress pulse.  ...
