Introduction to Stress Enhancement

What is/are Stress Enhancement?

Stress Enhancement - In addition, cyclic pressure causes redistribution and even change in the sign of the residual stresses, but this effect can be manifested as either stress relaxation or stress enhancement, depending on the initial residual stress. ^[1]

Field Stress Enhancement

The result of this new approach will be useful to understand partial discharge inception caused by electric field stress enhancement in transformer oil due to particle presence in oil gap between winding and pressboard barrier. ^[1] We conclude that the mode-I fractures in elliptical clasts are developed due to far-field stress enhancement inside the rigid clasts at shallow depth. ^[2]

Electric Stress Enhancement

Space charge accumulated in the bulk of dielectric materials may result in local electric stress enhancement and is indicated to play an important role in the degradation and even premature breakdown of insulators for high-voltage application. ^[1] This paper estimates the effect of electric stress enhancement on the various geometry of protrusions on the conductor and inner semiconductor compounds surface used with pulse voltage, say, 10 kV, with pulse width of 2ms applications. ^[2]

Yield Stress Enhancement

Klingenberg (University of Wisconsin–Madison, USA) presented ‘‘A jamming-like mechanism of yield stress enhancement of MR suspension mixtures of magnetizable and nonmagnetizable particles,’’ Prof. ^[1] % of sepiolite seems to combine a perfect sedimentation stability with moderate values of the plastic viscosity and of the off-state static yield stress (only ∼5 Pa) and with a relatively important static and dynamic yield stress enhancement (30% and 60%, respectively). ^[2]
