Dear All,
I'm a new UEL user. In my UEL I have a big Matrix which eigenvalues and eigenvectors of these matric is needed. the matrix is not changing during the time and it has constant elements. As you may know, calculating eigenvalues and eigenvectors is a time consuming procedure. In every time incerement, ABAQUS calculating eigenvalues and eigenvectors with bunch of other things in UEL.
The School of Engineering and Physical Sciences seeks to make two or more academic appointments to extend and enhance one or more of the core research elements in the Institute of Mechanical, Process and Energy Engineering (IMPEE).
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.
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

We are happy to announce an individual scholarship opportunities for international students for studying in International Master Degree Programme Advanced Dynamics of Discrete and Continuum Systems http://imechanica.org/node/16800 of Saint Petersburg State Polytechnical University.
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.

Sustainable development means meeting current needs without sacrificing the ability of future generations to meet their own needs. Sustainable development also means that maintenance, and enhance the rational use of the natural resource base, the foundation supports the anti-ecological pressures and economic growth.
