Kuwongolera kupsinjika kwa magalasi ndichinthu chofunikira kwambiri pakupanga magalasi, ndipo njira yogwiritsira ntchito chithandizo choyenera cha kutentha kuti muchepetse kupsinjika kwadziwika bwino kwa akatswiri agalasi.Komabe, momwe mungayesere molondola kupsinjika kwa galasi ndi imodzi mwamavuto ovuta omwe amasokoneza ambiri opanga magalasi ndi akatswiri, ndipo kuyerekezera kwachikhalidwe kwakhala kosayenera pazofunikira zamagalasi m'magulu amasiku ano.Nkhaniyi ikufotokoza mwatsatanetsatane njira zoyezera kupsinjika zomwe zimagwiritsidwa ntchito nthawi zambiri, ndikuyembekeza kukhala zothandiza ndikuwunikira mafakitale agalasi:

1. Maziko ongoyerekeza a kuzindikira kupsinjika:

1.1 Polarized kuwala

Ndizodziwika bwino kuti kuwala ndi mafunde a electromagnetic omwe amanjenjemera molunjika komwe akupita, kunjenjemera pamalo onse onjenjemera omwe amayang'ana kutsogolo.Ngati fyuluta ya polarization yomwe imalola kuti njira ina yogwedezeka idutse njira yowala ikayambitsidwa, kuwala kwa polarized kumatha kupezeka, komwe kumatchedwa polarized light, ndipo zida zowunikira zomwe zimapangidwa molingana ndi mawonekedwe a kuwala ndi polarizer.Polariscope Strain Viewer).YYPL03 Polariscope Strain Viewer

1.2 Birefringence

Galasi ndi isotropic ndipo ili ndi index yofananira yofanana mbali zonse.Ngati pali kupsinjika mugalasi, zinthu za isotropic zimawonongeka, zomwe zimapangitsa kuti index ya refractive isinthe, ndipo refractive index of the two main stress directions is no longer the same, that is, lead to birefringence.

1.3 Kusiyana kwa njira ya Optical

Kuwala kokhala ndi polarized kukadutsa mugalasi lolimba la makulidwe t, chowunikiracho chimagawika m'zigawo ziwiri zomwe zimanjenjemera munjira za x ndi y, motsatana.Ngati vx ndi vy ndi ma velocities a zigawo ziwiri za vector motsatana, ndiye kuti nthawi yoti mudutse pagalasi ndi t/vx ndi t/vy motsatana, ndipo zigawo ziwirizi sizikulumikizidwanso, ndiye kuti pali kusiyana kwa njira δ
