Amandla esivuno umqondo obalulekile emkhakheni wemishini yamapayipi angenamthungo.Inani lokucindezeleka lepayipi lensimbi engenamthungo lapho i-ductile ithela.Lapho ipayipi lensimbi engenamthungo lizokhubaza ngaphansi kwesenzo samandla, ukuguqulwa ngalesi sikhathi kungahlukaniswa ngezindlela ezimbili: ukuguqulwa kwepulasitiki kanye nokuguqulwa kwe-elastic.

1. I-deformation yepulasitiki ngeke iphele lapho amandla angaphandle ephela, futhi ipayipi yensimbi engenamthungo izoba ne-deformation unomphela.
2. Ukuguqulwa kwe-elastic kusho ukuthi ngaphansi kwesimo samandla angaphandle, lapho amandla angaphandle enyamalala, ukuguqulwa kuyophinde kunyamalale.

Amandla okukhiqiza nawo ayinani lokucindezeleka lepayipi elingenamthungo lapho liqala ukwenza ukuguqulwa kwepulasitiki, kodwa ngenxa yokuthi impahla ephukile ayidluli ukuguqulwa okusobala kwepulasitiki lapho yelulelwa ngamandla angaphandle, i-ductile kuphela enamandla okukhiqiza.

Lapha, amandla okukhiqiza amapayipi angenamthungo esibhekisela kuwo umkhawulo wesivuno lapho ukuvunwa kwenzeka, kanye nokucindezeleka ngokumelene nokuguqulwa kwe-micro-plastic.Uma amandla amakhulu kunalo mkhawulo, ingxenye izohluleka unomphela futhi ayikwazi ukutholwa.

Izici zangaphandle ezithinta amandla esivuno samapayipi angenamthungo yilezi: izinga lokushisa, izinga lobunzima, nesimo sokucindezeleka.Njengoba izinga lokushisa lincipha kanye nezinga lokucindezela likhuphuka, amandla okukhiqiza epayipi lensimbi engenamthungo nawo ayanda, ikakhulukazi uma i-cubic metal egxile emzimbeni izwela izinga lokushisa kanye nesilinganiso sobunzima, okuzobangela ukuvuthwa kwezinga lokushisa eliphansi kwensimbi.Ithonya esimweni sokucindezeleka libaluleke kakhulu.Nakuba amandla esivuno eyinkomba ebalulekile ebonisa ukusebenza kwangaphakathi kwempahla ekhiqiziwe, amandla esivuno ahlukile ngenxa yezimo ezihlukene zokucindezeleka.
Izici zangaphakathi ezithinta amandla esivuno yilezi: isibopho, inhlangano, isakhiwo, kanye nemvelo ye-athomu.Uma siqhathanisa amandla okukhiqiza ensimbi yepayipi engenamthungo nezinto zobumba kanye nezinto ze-polymer, singabona kukho ukuthi ithonya lezibopho zokubopha kuyinkinga eyisisekelo.
