Detailed Description

This class implements a 2-dimensional beam element with cubic lateral displacement interpolation (rotations are quadratic) and longitudial displacements are linear.

This is an exact displacement approximation for beam with no nonnodal loading.

This class is not derived from liBeam3d or truss element, because it does not support any material nonlinearities (if should, stiffness must be integrated)

virtual

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
answerMass matrix.
tStepTime step.
massTotal mass of receiver.

void oofem::Beam3d::computeStiffnessMatrix ( FloatMatrix answer,
MatResponseMode  rMode,
TimeStep tStep 
)
virtual

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
answerComputed stiffness matrix (symmetric).
rModeResponse mode.
tStepTime step.
