We show that the coupled balance equations for a large class of dissipative materials can be cast in the form of GENERIC (General Equations for Non-Equilibrium Reversible Irreversible Coupling). In dissipative solids, also called generalized standard materials, the state of a material point is decribed by dissipative internal variables in addition to the elastic deformation and the temperature....

the fuel cells are distinguished as generating of green allocable energy and are electrochemical devices of low environmental impact. porous nanocrystalline strontium-doped lanthanum manganite la0.8sr0.2mno3 (lsm) cathode materials were prepared by mechanochemical route in various grinding times. carbon black was employed to produce pores. the formation of lsm single phase was studied by x-ray ...

To increase the production efficiency of a typical turbine blade, it is necessary to change its material and hence its production technology. In this respect and in order to make sure that newmat...

Time-dependent creep analysis is presented for the calculation of stresses and displacements of axisymmetric thick-walled cylindrical pressure vessels made of functionally graded material (FGM). For the purpose of time-dependent stress analysis in an FGM pressure vessel, material creep behavior and the solutions of the stresses at a time equal to zero (i.e. the initial stress state) are needed....

High-dimensional optimization problems may be addressed using populational meta-heuristics, whose statistical properties may indicate important characteristics of the optimization process. There is a great number of these properties, which means their joint visualization may become impractical. We developed a method for sonically displaying characteristics of population dynamics in particle swa...

Problem statement: Improper understanding of material behavior prevents the efficient and correct usage of available materials and consequently, increases the construction and maintenance costs and even unsuitable construction. Considering the necessity of exact investigation about material behavior, several researches have been carried out in this field but the majority of these researches did...

attempts have been made for the first time to produce a friction material with thermal sensitive modulus by the inclusion of combined plastic/rubber properties of thermoplastic elastomers (tpe) as viscoelastic polymeric materials into the formulation for the purpose of increasing the damping behavior. in order to evaluate the viscoelastic parameters such as loss factor (tan δ) and elastic modul...

in spite of the fact that cementitious and concrete materials are mainly used on a large scale and inhuge quantities for roads, dams, bridges and building constructions, the mechanical behavior of thesematerials depends to a great extend on structural elements and phenomena which are effective on amicro and nanoscale. although this is well known by researchers, material producers and engineersf...
