Nanoindentation Response Analysis of Thin Film Substrates-II: Strain Hardening-Softening Oscillations in Subsurface Layer
No full textAbstract
We have extracted stress-strain field (SSF) gradient and divergence representations from nanoindentation data sets of bulk solids often used as thin film substrates: bearing and tooling steels, silicon, glasses, and fused silica. Oscillations of the stress-strain field gradient and divergence induced in the subsurface layer by the nanoindentation have been revealed. The oscillations are especially prominent in single indentation tests at shallow penetration depths, h<100 nm, whereas they are concealed in the averaged datasets of 10 and more single tests. The amplitude of the SSF divergence oscillations decays as a sublinear power-law when the indenter approaches deeper atomic layers, with an exponent −0.9 for the steel and −0.8 for the fused silica. The oscillations are interpreted as alternating strain hardening-softening plastic deformation cycles induced in the subsurface layer under the indenter load.</jats:p
Nanoindentation Response analysis of Thin Film Substrates-I: Strain Gradient-Divergence Approach
No full textAbstract
Nanoindentation is a widely-used method for sensitive exploration of the mechanical properties of micromechanical systems. We derive a simple empirical analysis technique to extract stress-strain field (SSF) gradient and divergence representations from nanoindentation data sets. Using this approach, local SSF gradients and structural heterogeneities can be discovered to obtain more detail about the sample’s microstructure, thus enhancing the analytic capacity of the nanoindentation technique. We demonstrate the application of the SSF gradient-divergence analysis approach to nanoindentation measurements of bulk silicon.</jats:p
Organization and legal basis of Karlis Ulmanis regime
No full textŠajā darbā tiek pētīta 1934. gada 15. maija valsts apvērsuma rezultātā radušās autoritatīvās valsts pārvaldes formas radītās pārmaiņas, to iespējamā nepieciešamība un tiesiskais pamatojums. Tiek secināts, ka Kārļa Ulmaņa un viņa līdzgaitnieku darbībai apvērsumā nebija tiesiska pamatojuma un tā bija krimināli sodāma saskaņā ar 1933. gada 24. aprīļa Soda likumu. Darba gaitā tiek izdarīti secinājumi par Kārļa Ulmaņa autoritārās varas sekām un to ietekmi uz Latvijas valsti un latviešu tautu, tostarp secinot, ka pēc 1936. gada 16. aprīļa Latvijas tautai vairs nepastāvēja iespēja ietekmēt likumdošanu un tā ir maldināta par tās iespējām ietekmēt likumdošanu, izmantojot Kameru sistēmu. Tiek vērsta uzmanība valsts varas pārņemšanas procesam un autoritatīvā vadītāja Kārļa Ulmaņa lomai jaunajā valsts iekārtā, kā arī procesam, kā tika organizēta jaunā valsts vara, secinot, ka tautas atbalsta gūšanai izmantoti neesoši draudi par pilsoņu kara izcelšanos, un ka tobrīd pastāvošās atsevišķās radikālās organizācijas patiesībā neradīja draudus demokrātiskas Latvijas pastāvēšanai. Tiek identificēti konkrēti cilvēki, kuri bija atbildīgi par valsts varas dalīšanas principa pārtraukšanu, apvienojot lēmējvaru un izpildvaru. Atslēgas vārdi: Apvērsums, Autoritārisms, Kārlis Ulmanis, Valsts vara, Kameru sistēmaThis paper examines the May 15, 1934 coup d’état of Latvia, focusing on the resulting changes, their possible necessity and the legal justification of the newly created authoritarian government. This study determines that the actions of Karlis Ulmanis and his accomplices did not have legal justification and were criminally punishable according to the April 24, 1933 Penalty law. The author draws conclusions about the consequences and influence of Karlis Ulmanis authoritarian rule on the Latvian state and Latvian people, and finds that after April 16, 1936 citizens of Latvia no longer had any effective influence on the legislation of Latvia and were misled about their influence over legislation through the Camera system. The study examines the process of how the coup took place and how the new state power was organized and finds that the usurpers used nonexistent threats of a civil war break-out in order to gain public support, and that the few existing radical organizations did not pose a substantial threat to the existence of a democratic Latvian state. Additionally, individuals are identified that were responsible for the abolishment of the division of executive and legislative powers. Key words: Coup d'état, authoritarianism, Karlis Ulmanis, state power, camera system
