Neo-fascism movements such as the National Alliance, and the American Nazi Party. The Institute for Historical Review publishes negationist historical papers often of an anti-semitic nature. The alt-right—which covers a broad range of groups, from authoritarian right-wing technocrats and neo-monarchists to neoreactionaries and white nationalists—is also often included under the umbrella term "neo-fascist", as many adhere to a radically authoritarian philosophy. In 1951, the New European Order (NEO) neo-fascist Europe-wide alliance was set up to promote Pan-European nationalism. It was a more radical splinter group of the European Social Movement. The NEO had its origins in the 1951 Malmö conference when
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
