Dimensional Stability of Reinforced Matrices

1983
Particulate fillers are often used to improve the dimensional stability of polymeric items obtained through processing techniques such as injection molding, deep drawing, hot stamping, etc. In these operations the material undergoes large multiaxial deformations which result in molecular orientation and remain as frozen-in stresses during cooling of ...

The effect of SiC addition on the dimensional stability of Al-Cu-Mg alloy

Journal of Alloys and Compounds, 2018
Due to the high specific stiffness and low coefficient of thermal expansion, the SiC particles are introduced to improve the dimensional stability of Al-Cu-Mg (2024 aluminum) alloy in present work. The intergrated effects of SiC and aging precipitates on

Dimensional stability of temporary restoratives

Oral Surgery, Oral Medicine, Oral Pathology, 1975
The effects of thermal cycling on the dimensional stability of temporary restoratives were studied. Stability appeared to be affected significantly by water content. On thermal cycling, Cavit showed less linear dimensional change than two cements containing zinc oxide-eugenol and gutta-percha temporary stopping.

ON STABILIZING N-DIMENSIONAL CHAOTIC SYSTEMS

International Journal of Bifurcation and Chaos, 2003
This paper deals with the control of a class of n-dimensional chaotic systems. The proposed method consists in a Variable Structure Control approach based on system energy consideration for both controller design and system stabilization. First, we present some theoretical results related to the stabilization of global invariant sets included in a ...
