maxPrinsipal()

double FFaTensor2::maxPrinsipal

(

bool

absMax = false

)

const

Get the (absolute) max principal of the tensor. If it can't be found, HUGE_VAL will be returned.

maxShear() [1/2]

double FFaTensor2::maxShear

(

)

const

Get the max shear value of the tensor. If it can't be found, HUGE_VAL will be returned.

maxShear() [2/2]

void FFaTensor2::maxShear

(

FaVec3 &

v

)

const

Get the max shear of the tensor as a directed vector. If it can't be found, a 0-vector will be returned.

minPrinsipal()

double FFaTensor2::minPrinsipal

(

)

const

Get the min principal of the tensor. If it can't be found, HUGE_VAL will be returned.

prinsipalValues() [1/2]

void FFaTensor2::prinsipalValues	(	double &	max,
		double &	min
	)		const

Get the principal values of the tensor. If they can't be found, HUGE_VAL will be returned.

prinsipalValues() [2/2]

void FFaTensor2::prinsipalValues	(	FaVec3 &	values,
		FaMat33 &	rotation
	)		const

Get a valid rotation matrix corresponding to the principal axes of the tensor. The associated principal values are also found in the corresponding order. If the matrix can't be found, the identity will be returned, along with a vector of HUGE_VAL.

rotate()

FFaTensor2 & FFaTensor2::rotate	(	const double	ex[2],
		const double	ey[2]
	)

Rotate the tensor to the given CS.

vonMises()
