WebThe elastic tensor (in Voigt notation) is printed to the output file and stored in the engine result file in the AMSResults section (for 3D system, the elastic tensor in Voigt notation is a 6x6 matrix; for 2D systems is a 3x3 matrix; for 1D systems is just one number). WebThe elasticity matrix in the Voigt (11, 22, 33, 23, 13, 12) Material data orderingchanges the sorting of the last three elements in the elasticity matrix: If a pair of elastic moduli is present in the material definition, the values of Ex, Ey, Ez, νxy, νyz, νxz, Gxy, Gyz, and Gxzare computed automatically.

Tensor Notation

WebIn continuum mechanics, the Cauchy stress tensor, true stress tensor, or simply called the stress tensor is a second order tensor named after Augustin-Louis Cauchy.The tensor consists of nine components that completely define the state of stress at a point inside a material in the deformed state, placement, or configuration. The tensor relates a unit … WebTo overcome this difficulty, Voigt matrix notation has been introduced to allow the stiffness tensor to be written as a matrix. This Voigt matrix notation consists of replacing or by or , … WebSimilarly, if we consider a purely mechanical system with linear constitutive relations of the form [bar.S] = [??][bar.T] where [bar.S] is the strain, [bar.T] the stress and [??] the … how to use a metal lathe for beginners
