Neo-völkisch movements forms and esoteric themes, so that neo-"völkisch" currents often have the character of new religious movements. Included under the neo-"völkisch" umbrella are movements ranging from conservative revolutionary schools of thought ("Nouvelle Droite", European New Right, Evolian Traditionalism) to white supremacist and white separatist interpretations of Christianity, pantheism and paganism (Christian Identity, Creativity Movement, Cosmotheism, Nordic racial paganism) to Neo-Nazi subcultures (Esoteric Hitlerism, Nazi Satanism, National Socialist black metal). According to the Southern Poverty Law Center, only pagan-type groups are recognized as "Neo-Volkisch", excluding Christian Identity. Among the terms used are Nazi Satanism and Fascist Satanism. Sometimes these groups self-identify as
Neo-Hookean solid the left Cauchy-Green deformation tensor is In this case formula_76. Hence, formula_77. Now, Hence the Cauchy stress is given by Using the relation for the Cauchy stress for an incompressible neo-Hookean material we get Thus neo-Hookean solid shows linear dependence of shear stresses upon shear deformation and quadratic dependence of the normal stress difference on the shear deformation. Note that the expressions for the Cauchy stress for a compressible and an incompressible neo-Hookean material in simple shear represent the same quantity and provide a means of determining the unknown pressure formula_27. Neo-Hookean solid A neo-Hookean solid is a hyperelastic material
