Lub hauv paus ntsiab lus ntawm kev tiv thaiv armor yog siv lub zog ntawm qhov projectile, qeeb nws thiab ua rau nws tsis muaj mob. Feem ntau cov khoom siv hluav taws xob, xws li hlau, nqus lub zog los ntawm cov txheej txheem deformation, thaum cov ntaub ntawv ceramic nqus zog los ntawm cov txheej txheem micro-fragmentation.

Lub zog nqus cov txheej txheem ntawm mos mos ceramics tuaj yeem muab faib ua 3 theem.

(1) Kev cuam tshuam rau theem pib: qhov cuam tshuam rau ntawm lub ntsej muag ceramic, kom lub taub hau blunt, nyob rau hauv ceramic nto crushed los tsim ib tug nplua thiab nyuaj fragmentation nyob rau hauv tus txheej txheem ntawm lub zog nqus.

(2) Erosion theem: blunted projectile txuas ntxiv mus rau qhov chaw tawg, tsim ib txheej txuas ntxiv ntawm cov khoom tawg.

(3) Deformation, tawg, thiab tawg theem: thaum kawg, tensile stresses yog generated nyob rau hauv lub ceramic ua rau nws tawg, ua raws li los ntawm lub deformation ntawm lub backing phaj, nrog tag nrho cov seem zog absorbed los ntawm lub deformation ntawm cov ntaub ntawv thaub qab. Thaum lub sij hawm cuam tshuam ntawm qhov projectile ntawm lub ceramic, ob qho tib si lub projectile thiab ceramic yog puas.

Dab tsi yog cov khoom siv kev ua tau zoo rau cov mos txwv-pov thawj ceramics?

Vim tias qhov nkig ntawm cov ceramic nws tus kheej, nws tawg tsis yog deforms thaum cuam tshuam los ntawm qhov projectile. Nyob rau hauv tensile loading, pob txha tawg tshwm sim thawj zaug ntawm qhov chaw uas tsis yog homogeneous xws li pores thiab grain ciam teb. Yog li ntawd, txhawm rau txo qis kev ntxhov siab ntawm microscopic, armor ceramics yuav tsum yog cov khoom zoo nrog cov porosity tsawg thiab cov qauv zoo.
