But there are the calculated difficulties for the equations, which take place for nonlinear hyperbolic systems. In this connection, It is necessary to impose the additional restrictions which assure the existence and unique of solutions. As test sample, we use the free wave packet and study its behavior at the different initial and boundary conditions. The calculations of wave packet propagation cause in numerical algorithm the division. In numerical algorithm at the calculations of wave packet propagation, there arises the problem of division by zero. To overcome this problem we have to sew together discrete numerical and analytical continuous solutions on the boundary. We demonstrate here for the free wave packet that the numerical solution corresponds to the analytical solution.","PeriodicalId":117315,"journal":{"name":"Nanodesign, Technology, and Computer Simulations","volume":"13 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130445314","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This effect is connected with a small decreasing (or increasing) of temperature in a mechanically loaded solid. Recently it was shown, that this effect has cornpletely anharmonic nature.

In this communication a generating function method is proposed for the energy balance calculation.

It is shown that the self-organization of chaos consists of several stages during which two motive forces (attractive and repulsive) are generated, and totally disordered chaos transforms into partially ordered. It is found that there are five world lines of self-organization: water, light, cosmos-weather, water-fire, and State evolution.","PeriodicalId":117315,"journal":{"name":"Nanodesign, Technology, and Computer Simulations","volume":"68 5 Pt 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116376673","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In the presented article for this kind of measurements, the use of X-ray diffractometer has been shown. The advantage of the method presented is that, apart from precise dependence measurement between the temperature of a monocrystal and the value of piezoelectric tensor elements, it enables synchronous measurement of the value of thermal expansion tensor elements for a monocrystal.","PeriodicalId":117315,"journal":{"name":"Nanodesign, Technology, and Computer Simulations","volume":"185 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131481514","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Specimens were made of industrial material (amorphous metallic glass) and represented thin films (20x10x0.03 mm). They were annealed in an oven and then their mechanical properties and structures were defined by microindentation on different polymer substrates and X- ray powder technique. X-ray study exposes a complicated phase transformation process within the temperature range, which includes four different structural states: amorphous, two metastable, and \"stable\". Average particle size was estimated to be 30-50 nm according to broadening of diffraction maximum. Microindentation tests indicate two maximums of Vickers microhardness, whose locations correspond to the metastable structural states independently on the used substrate material. These allows us to conclude following. It is possible to observe directly qualitative correlation between structure and mechanical properties of metallic nanomaterial - annealed metallic glass. Used method of microindentation is structure-sensitive. Registered X-ray patterns draw detailed picture of the complicated phase transformation process, which needs to be investigated further. Discussed correlation allows us to suppose existence of similar correlation between structure and chemical, electromagnetic, or other macroscopic properties of the material.","PeriodicalId":117315,"journal":{"name":"Nanodesign, Technology, and Computer Simulations","volume":"611 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-02-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126907534","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We simulate the deformation field during the diffusion caused by the gradients of the chemical potential of all elements. The method is based on the Darken concept and calorimetric equation of state. We effectively couple the mass conservation (continuity equations) with the energy and momentum conservation laws. The diffusion fluxes ofthe components are given by the Nernst-Planck formulae and take into account the chemical and mechanical potentials. We are presenting the numerical results for Cu-Fe-Ni alloy. The simulations shows that the model is compatible with experimental results, and can be effectively used for modeling the energy, momentum and mass transport problems in compressible multicomponent solid solutions. The mechano-chemical transport is a multi-scale problem. The transport is governed by strain field characterized by \"sound velocity\" in the medium (~104ms-1) and slow diffusion process characterized by self-velocity of diffusion (~10-2ms-1).
