Detailed Description

This class implements a 3-dimensional Linear Isoparametric Mindlin theory beam element, with reduced integration. Geometric nonlinearities are taken into account. Based on Element due to Simo and Vu-Quoc, description taken from Crisfield monograph. Similar to Libeam3dNL, but rotational update is done using quaternions.

void oofem::LIBeam3dNL2::computeBmatrixAt	(	GaussPoint *	gp,
		FloatMatrix &	answer,
		int	lowerIndx,
		int	upperIndx )

inlineoverrideprotectedvirtual

Computes the geometrical matrix of receiver in given integration point. The product of this matrix (assembled at given integration point) and element displacement vector is element strain vector. If lowerIndx and upperIndx parameters are specified, answer is formed only for strains within this interval. This will affects the size of answer.

Parameters

gp	Integration point for which answer is computed.
answer	Geometric matrix of receiver.
lowerIndx	If specified, answer is formed only for strain with index equal and greater than lowerIndx. This parameter has default value 1 (answer is formed from first strain).
upperIndx	If specified, answer is formed only for strain with index less and equal than upperIndx. This parameter has default value ALL_STRAINS (answer is formed for all strains).

Computes the load vector due to body load acting on receiver, at given time step. Default implementation computes body load vector numerically as \( l=\int_V N^{\mathrm{T}} f \rho\;\mathrm{d}V \) using default integration rule. Result is transformed to global c.s.

Parameters

answer	Computed load vector due to body load
load	Body load which contribution is computed.

◆ computeConsistentMassMatrix()

void oofem::LIBeam3dNL2::computeConsistentMassMatrix	(	FloatMatrix &	answer,
		TimeStep *	tStep,
		double &	mass,
		const double *	ipDensity = NULL )

inlineoverridevirtual

Computes consistent mass matrix of receiver using numerical integration over element volume. Mass matrix is computed as \( M = \int_V N^{\mathrm{T}} \rho N dV \), where \( N \) is displacement approximation matrix. The number of necessary integration points is determined using this->giveNumberOfIPForMassMtrxIntegration service. Only selected degrees of freedom participate in integration of mass matrix. This is described using dof mass integration mask. This mask is obtained from this->giveMassMtrxIntegrationgMask service. The nonzero mask value at i-th position indicates that i-th element DOF participates in mass matrix computation. The result is in element local coordinate system.

Parameters

answer	Mass matrix.
tStep	Time step.
mass	Total mass of receiver.

◆ computeLumpedMassMatrix()

void oofem::LIBeam3dNL2::computeLumpedMassMatrix	(	FloatMatrix &	answer,

overridevirtual

Computes lumped mass matrix of receiver. Default implementation returns lumped consistent mass matrix. Then returns lumped mass transformed into nodal coordinate system. The lumping procedure zeroes all off-diagonal members and zeroes also all diagonal members corresponding to non-displacement DOFs. Such diagonal matrix is then rescaled, to preserve the element mass. Requires the computeNmatrixAt and giveMassMtrxIntegrationgMask services to be implemented.

Parameters

answer	Lumped mass matrix.
tStep	Time step.

◆ computeStiffnessMatrix()

void oofem::LIBeam3dNL2::computeStiffnessMatrix	(	FloatMatrix &	answer,
		MatResponseMode	rMode,
		TimeStep *	tStep )

overridevirtual

Computes numerically stiffness matrix of receiver. Default implementation computes element stiffness using \( K=\int_v B^{\mathrm{T}} D B \mathrm{d}V \) formulae, where \( B \) is element geometric matrix and \( D \) is material stiffness matrix. No geometrical nonlinearity is taken into account. NUmerical integration procedure uses integrationRulesArray for numerical integration. Support for reduced or selected integration is implemented. The individual integration rules are assumed to correspond to different terms from which the overall matrix is assembled.

If there is one integration rule, the full integration of all coefficients is performed. Otherwise, integration is performed using following rules. Each integration rule can specify start and end strain index of strain vector components for which is valid. It is necessary to ensure that these start and end indexes, dividing geometrical matrix into blocks, are not overlapping and that each strain component is included.

Then stiffness matrix is obtained as summation of integrals \( I_{ij}=\int_v B^{\mathrm{T}}_i D_{ij} B_j \mathrm{d}V \) where \( B_i \) is i-th block of geometrical matrix and \( D_{ij} \) is corresponding constitutive sub-matrix. The geometrical matrix is obtained using computeBmatrixAt service and the constitutive matrix is obtained using computeConstitutiveMatrixAt service. The \( I_{ij} \) integral is evaluated using such integration rule, which is valid for i-th or j-th block and has smaller number of integration points.

For higher numerical performance, only one half of stiffness matrix is computed and answer is then symmetrized. Therefore, if element matrix will be generally nonsymmetric, one must specialize this method. Finally, the result is transformed into global coordinate system (or nodal coordinate system, if it is defined).

Parameters

answer	Computed stiffness matrix (symmetric).
rMode	Response mode.
tStep	Time step.

◆ giveInternalForcesVector()

void oofem::LIBeam3dNL2::giveInternalForcesVector	(	FloatArray &	answer,

Default implementation computes result as \( F=\int_v B^{\mathrm{T}} \sigma \mathrm{d}V \), where \( \sigma \) is the real element stress vector obtained using computeStressVector service (if useUpdatedGpRecord=0) or (if useUpdatedGpRecord=1) from integration point status.

Integration is performed using default integration rule, which should produce always valid results, assuming that strains used for computation of stresses are valid.

Parameters

answer	Internal nodal forces vector.
tStep	Time step.
useUpdatedGpRecord	If equal to zero, the stresses in integration points are computed (slow but safe), else if nonzero the stresses are taken directly from integration point status (should be derived from StructuralMaterialStatus) (fast, but engineering model must ensure valid status data in each integration point).
