This page describes the python modules based on the
TFEL libraries.
tfel.math modulestensor classThree classes standing for symmetric tensors are available:
Stensor1D: symmetric tensor in \(1D\).Stensor2D: symmetric tensor in \(2D\).Stensor3D: symmetric tensor in \(3D\).The standard mathematical operations are defined:
The following functions are available:
sigmaeq: computes the von Mises norm of a symmetric
tensor.tresca: computes the Tresca norm of a symmetric
tensor.st2tost2 classThree classes standing for linear transformation of symmetric tensors to symmetric tensors:
ST2toST1D: linear transformation of symmetric tensors
to symmetric tensors in \(1D\).ST2toST2D: linear transformation of symmetric tensors
to symmetric tensors in \(2D\).ST2toST3D: linear transformation of symmetric tensors
to symmetric tensors in \(3D\).tfel.material
moduleThe following functions are available:
buildFromPiPlane: returns a tuple containing the three
eigenvalues of the stress corresponding to the given point in the \(\pi\)-plane.projectOnPiPlane: projects a stress state, defined its
three eigenvalues or by a symmetric tensor, on the \(\pi\)-plane.The computeHosfordStress function, which compute the
Hosford equivalent stress, is available.
The following functions are available:
makeBarlatLinearTransformation1D: builds a \(1D\) linear transformation of the stress
tensor.makeBarlatLinearTransformation2D: builds a \(2D\) linear transformation of the stress
tensor.makeBarlatLinearTransformation3D: builds a \(3D\) linear transformation of the stress
tensor.computeBarlatStress: computes the Barlat equivalent
Barlat stress.
