Bihurketa formulak
Material elastiko lineal isotropiko homogeneoek goian zehaztutako bi moduluren bidez soilik zehazten dira beren propietate elastikoak, beraz, beste edozein elastikotasun modulu kalkula daiteke formula hauen arabera.

Hooke-ren legea (3Dn) zurruntasun-matrizea (9 x 9, edo 6 x 6 Voigt notazioan) bi osagairekin soilik parametriza daiteke material homogeneo eta isotropoetarako. Goian emandako elastikotasun moduluen artean nahiago den bikotea aukeratu daiteke. Bihurketa posible batzuk taulan zerrendatzen dira.
