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.
