Constructor & Destructor Documentation

DruckerPragerRheology() [1/2]

DruckerPragerRheology::DruckerPragerRheology

(

)

Constructs a rheology with no fragmentation model.

Stress tensor is only modified by von Mises criterion, yielding strength does not depend on damage.

DruckerPragerRheology() [2/2]

DruckerPragerRheology::DruckerPragerRheology

(

AutoPtr< IFractureModel > &&

Member Function Documentation

create()

void DruckerPragerRheology::create ( Storage &  storage, IMaterial &  material, const MaterialInitialContext &  context  ) const

overridevirtual

Creates all the necessary quantities and material parameters needed by the rheology.

The function is called for each body added to the simulation.

Parameters

storage	Particle storage, containing particle positions and their masses (optionally also other quantities). Particles belong only to the body being created, other bodies have separate storages.
material	Material containing input material parameters. The rheology may sets the timestepping parameters (range and minimal values) of the material.
context	Shared data for creating all materials in the simulation.

Todo:

user defined max value

Implements IRheology.

Definition at line 104 of file Rheology.cpp.

initialize()

void DruckerPragerRheology::initialize ( IScheduler &  scheduler, Storage &  storage, const MaterialView  material  )

overridevirtual

Evaluates the stress tensor reduction factors.

Called for every material in the simulation every timestep, before iteration over particle pairs

Parameters

scheduler	Scheduler used for parallelization.
storage	Storage including all the particles.
material	Material properties and sequence of particles with this material. Implementation should only modify particles with indices in this sequence.

Implements IRheology.

Definition at line 119 of file Rheology.cpp.

integrate()

void DruckerPragerRheology::integrate ( IScheduler &  scheduler, Storage &  storage, const MaterialView  material  )

overridevirtual

Computes derivatives of the time-dependent quantities of the rheological model.

Called for every material in the simulation every timestep, after all derivatives are computed.

Parameters

scheduler	Scheduler used for parallelization.
storage	Storage including all the particles.
material	Material properties and sequence of particles with this material. Implementation should only modify particles with indices in this sequence.

Implements IRheology.
