摘要: A new theoretical analysis is made of the elastic constants crystalline native cellulose. Primary interatomic forces are considered in calculation Young modulus chain direction, where we retrieve a result identical to that Treloar. Hydrogen bonds provide main mechanism for determining all other constants, most which here calculated first time. The lateral moduli found be surprisingly high. Van der Waals interactions assumed play subsidiary role hydrogen bonds, but this factor remains quantitatively assessed. relation theory experiment critically examined.
