Amahame y'ishusho ya Polariscope yerekeye uburyo bwo kureba strain

Kugenzura uburemere bw'ibirahuri ni ingenzi cyane mu ikorwa ry'ibirahuri, kandi uburyo bwo gukoresha uburyo bukwiye bwo kuvura ubushyuhe mu kugenzura uburemere bw'ibirahuri buzwi cyane n'abatekinisiye b'ibirahuri. Ariko, uburyo bwo gupima neza uburemere bw'ibirahuri buracyari kimwe mu bibazo bikomeye bibangamira abakora ibirahuri n'abatekinisiye benshi, kandi isuzuma rishingiye ku buhanga risanzwe ryarushijeho kuba ritajyanye n'ubuziranenge bw'ibirahuri mu muryango w'iki gihe. Iyi nkuru igaragaza uburyo busanzwe bwo gupima uburemere bw'ibirahuri, yizeye ko buzafasha kandi bukangura inganda z'ibirahuri:

1. Ishingiro ry'inyigisho zo kumenya imihangayiko:

1.1 Urumuri rwa polarized

Birazwi neza ko urumuri ari umuraba wa elegitoroniki unyeganyega mu cyerekezo giteganye n’icyerekezo cy’imbere, uganyeganyega ku buso bwose bunyeganyega buteganye n’icyerekezo cy’imbere. Iyo hashyizweho akayunguruzo ka polarization kemerera gusa icyerekezo runaka cy’inyeganyega mu nzira y’urumuri, urumuri rwa polarized rurashobora kuboneka, rwitwa urumuri rwa polarized, kandi ibikoresho bya optique bikozwe hakurikijwe imiterere ya optique ni polarizer (Ishusho y'Uburibwe bwa Polariscope).YYPL03 Polariscope Strain Viewer

1.2 Kugabanya ingano y'ibice bibiri

Ikirahure ni isotropic kandi gifite igipimo kimwe cyo kugarura urumuri mu mpande zose. Iyo hari stress mu kirahure, imiterere ya isotropic irangirika, bigatuma igipimo cyo kugarura urumuri gihinduka, kandi igipimo cyo kugarura urumuri mu byerekezo bibiri by'ingenzi byo kugarura urumuri ntikiba kimeze kimwe, ni ukuvuga ko birefringence iba ihari.

1.3 Itandukaniro ry'inzira y'urumuri

Iyo urumuri rwa polarized runyuze mu kirahure gifite ubugari bwa t, vector y'urumuri igabanyukamo ibice bibiri bihinda mu cyerekezo cya x na y, uko bikurikirana. Niba vx na vy ari umuvuduko w'ibice bibiri bya vector uko bikurikirana, igihe gisabwa kugira ngo kinyure mu kirahure ni t/vx na t/vy uko bikurikirana, kandi ibice byombi ntibikivangavanze, noneho habaho itandukaniro ry'inzira y'urumuri δ.
