Machira akarukwa anogadzirwa neshinda dzakachinjika dzakachinjika neshinda, zvichikonzera kuti ive yakasimba uye yakagadzikana. Izvi zvinovapa mabhenefiti akadai seabrasion kuramba uye kuramba deformation, asi zvakare zvinotungamira kune hurombo hwechisikigo elasticity. Semuenzaniso, kuchinjika/kurebesa kurebesa kwedonje chairo kana machira epolyester akarukwa kazhinji ari pasi pe5%, akadzikira zvakanyanya kupfuura 30% -50% yemachira akarukwa. Nekudaro, elasticity haisi zero zvachose:
1. Hunhu hweshinda: Dzimwe shinda dzechisikigo (dzakadai semvere dzemakwai) kana shinda dzakatetepa dzinogona kupa kusimba kushoma, asi dzakaoma kudzoka zvizere kuchimiro chadzo chepakutanga mushure mekutambanudza.
2. Kufurira kwedhanda remachira: Machira akarukwa akaderera-akaita segauze) anogona kuburitsa mitsetse mishoma nekuda kwemukaha mukuru pakati peshinda, asi ari nyore kuremara.
