a rank two symmetric strain tensor, in the double convention of the Voigt notation; type= says whether it refers to the undeformed configuration, ‘Lagrange’ (the default), or to the deformed one, ‘Euler’, MATLAB’s strainTensor(M, ‘type’, ‘Euler’), and is kept by everything derived from it

Syntax

eps = strainTensor(M)
eps = strainTensor(M, cs)
eps = strainTensor(np.diag([1, 0, -1]))
eps = strainTensor(M, type='Euler')
eps.type

Input

`M`	symmetric rank-two coefficients or six-component Voigt vectors, or another tensor
`args`	optional reference frame
`type`	‘Lagrange’ for the reference configuration or ‘Euler’ for the current configuration
`kwargs`	tensor constructor options; engineering Voigt convention is used by default

Signature

strainTensor(M, *args, type=None, **kwargs)

Used on

AnisotropicTheory, SachsModel, TaylorHex, TaylorModel, TextureEvolution, SO3FunVectorField, TensorArithmetics, TensorDefinition
