Detailed Description

template<typename T>
class b2000::SolidMechanics25D< T >

The base class for the material API for 2.5D (shell) stress elements.

The strain, stress and constitutive tensor follow the notation used in the book "Finite Element Procedures" by K.J. Bathe:

The strain covariant components are placed in column vector [e11, e22, e33, 2e12, 2e23, 2e13].

The stress contravariant components are placed in column vector [s11, s22, s33, s12, s23, s13].

The constitutive contravariant components are placed in lower packed matrix format

Member Function Documentation

copy()

template<typename T >

virtual SolidMechanics25D< T > * b2000::SolidMechanics25D< T >::copy ( int  layer_ )

inlinevirtual

Create a copy of the object to be used in nonlinear analysis of path dependent material.

get_shell_stress()

template<typename T >

virtual void b2000::SolidMechanics25D< T >::get_shell_stress ( Model *  model, const EquilibriumSolution  equilibrium_solution, const double  time, const double  delta_time, GradientContainer *  gradient_container, SolverHints *  solver_hints, const Element *  element, const double  el_coordinates[2], const b2linalg::Vector< double, b2linalg::Vdense_constref >  nodes_interpolation, const T  bg_coordinates[3], const T  covariant_base[6][3], const bool  use_covariant_base, const T  volume, const T  displacement_gradient[6][3], const T  shell_strain[8], const T  strain_dot[8], const T  velocity[6], const T  acceleration[6], T  shell_stress[8], T  d_shell_stress_d_strain[36], T  d_stress_d_strain_dot[36], T  d_shell_stress_d_time[8], T  d_stress_d_time[6], T  inertia_force[6], T  density[3]  )

inlinevirtual

Return the shell stress of the material

get_static_nonlinear_shell_stress()

template<typename T >

virtual void b2000::SolidMechanics25D< T >::get_static_nonlinear_shell_stress ( Model *  model, const EquilibriumSolution  equilibrium_solution, const double  time, const double  delta_time, GradientContainer *  gradient_container, SolverHints *  solver_hints, const Element *  element, const double  el_coordinates[2], const b2linalg::Vector< double, b2linalg::Vdense_constref >  nodes_interpolation, const T  bg_coordinates[3], const T  covariant_base[6][3], const bool  use_covariant_base, const T  displacement_gradient[6][3], const T  shell_strain[8], T  shell_stress[8], T  d_shell_stress_d_strain[36], T  d_shell_stress_d_time[8]  )

inlinevirtual

Return the static shell stress of the material

isotropic()

template<typename T >

virtual bool b2000::SolidMechanics25D< T >::isotropic ( const int  layer_id = -1 ) const

inlinevirtual

Returns

true if the material is isotropic. In this case, the natural base is not used by the material object and can be omitted (passing a null pointer).

If layer_id is not given, the isotropic propriety is for all the laminate (note that a laminate with more than on layer is not isotropic). Otherwise the isotropic propriety is for the given layer.

Reimplemented in b2000::b2dbv3::ElementPropertyStressExample25D, and b2000::b2dbv3::ElementPropertyStressExample.

linear()

template<typename T >

virtual LinearType b2000::SolidMechanics25D< T >::linear ( const int  layer_id = -1 ) const

inlinevirtual

Returns

'linear' if the material is linear. In this case, a nonlinear analysis can use the linear methods instead of the nonlinear ones. Return nonlinear if the material is nonlinear. Return linear_on_sub_domain if the material is linear only on a sub domain of the strain value

If layer_id is not given, the linearity propriety is for all the layers. Otherwise the linearity propriety is for the given layer.

Reimplemented in b2000::b2dbv3::ElementPropertyStressExample25D, and b2000::b2dbv3::ElementPropertyStressExample.

path_dependent()

template<typename T >

virtual bool b2000::SolidMechanics25D< T >::path_dependent ( const int  layer_id = -1 ) const

inlinevirtual

Returns

true if the material is path dependent. In this case and if a nonlinear analysis is performed, the material object must by copied for each integration point. That is for each material points where the nonlinear method get_static_nonlinear_stress or get_dynamic_nonlinear_stress are called during the analysis.

If layer_id is not given, the path-dependent propriety is for all the laminate. Otherwise the path-dependent propriety is for the given layer.

Reimplemented in b2000::b2dbv3::ElementPropertyStressExample.

set_static_nonlinear_shell_stress()

template<typename T >

virtual void b2000::SolidMechanics25D< T >::set_static_nonlinear_shell_stress ( Model *  model, const double  time, const double  delta_time, GradientContainer *  gradient_container, const Element *  element, const double  el_coordinates[2], const b2linalg::Vector< T, b2linalg::Vdense_constref >  nodes_interpolation, const T  bg_coordinates[3], const T  covariant_base[6][3], const bool  use_covariant_base, const T  displacement_gradient[6][3], const T  shell_strain[8], const T  shell_stress[8], const T  d_shell_stress_d_ec[2][8]  )

inlinevirtual

Set the stress and derivative value in the gradient container
