ComputeInertiaMatrix()

virtual void chrono::fea::ChInertiaCosserat::ComputeInertiaMatrix ( ChMatrixNM< double, 6, 6 > &  M )

pure virtual

Compute the 6x6 sectional inertia matrix, as in {x_momentum,w_momentum}=[Mm]{xvel,wvel} The matrix is computed in the material reference (i.e.

it is the sectional mass matrix)

Parameters

M	6x6 sectional mass matrix values here

Implemented in chrono::fea::ChInertiaCosseratAdvanced, and chrono::fea::ChInertiaCosseratSimple.

ComputeQuadraticTerms()

virtual void chrono::fea::ChInertiaCosserat::ComputeQuadraticTerms ( ChVector<> &  mF, ChVector<> &  mT, const ChVector<> &  mW  )

pure virtual

Compute the values of inertial force & torque depending on quadratic velocity terms, that is the gyroscopic torque and the centrifugal term (if any).

All terms expressed in the material reference, ie. the reference in the centerline of the section.

Parameters

mF	centrifugal term (if any) returned here
mT	gyroscopic term returned here
mW	current angular velocity of section, in material frame

Implemented in chrono::fea::ChInertiaCosseratAdvanced, and chrono::fea::ChInertiaCosseratSimple.

GetMassPerUnitLength()

virtual double chrono::fea::ChInertiaCosserat::GetMassPerUnitLength ( )

pure virtual

Compute mass per unit length, ex.SI units [kg/m].

This is also the(0, 0) element in the sectional inertia matrix.

Implemented in chrono::fea::ChInertiaCosseratAdvanced, and chrono::fea::ChInertiaCosseratSimple.
