Electromechanical deformation of dielectric elastomer in two types of pre-stretch
A pre-stretched dielectric elastomer is capable of large deformation, when subject to voltage. This paper investigates the effect of two types of pre-stretch: by strain and by stress. The difference is compared and discussed using thermodynamics models. The significance of the pre-stretch in actuation is explained by examining the true stress in actuation. Under both pre-stretch strategies, during the actuation, the dielectric elastomer exhibits hysteresis loops due to snap-through but differs in shape and physical quantity.
Three interesting, recent books
Dear friends:
I’d like to bring to your attention three recently published books that I have read. The following are a few words about each book in the order that I read them.
1) “Vito Volterra” by A. Guerraggio and G. Paoloni

'Influence of factors unrelated to environmental quality on occupant satisfaction in LEED and non-LEED certified buildings'
The article from Building and Environment featured in this piece 'Influence of factors unrelated to environmental quality on occupant satisfaction in LEED and non-LEED certified buildings' by Stefano Schiavon and Sergio Altomonte, can be viewed freely until 31 August 2014 http://bit.ly/1pTxID8
What is the importance of strain rate on structural response under blast load?
What is the importance of strain rate on structural response under blast load?
This and other issues are discussed in the recent paper from Stochino F. and Carta G.:
“SDOF models for reinforced concrete beams under impulsive loads accounting for strain rate effects”, DOI: 10.1016/j.nucengdes.2014.05.022, Nuclear Engineering and Design 276, (2014), 74-86.
