Detailed Description

Drucker-Prager material.

Member Function Documentation

getValues()

XC::Matrix XC::DruckerPrager::getValues ( const std::string &  cod, bool  silent = false  ) const

virtual

Returns material response.

Parameters

cod	name of the requested value.
silent	if true don't complain about non-existen property.

Reimplemented from XC::NDMaterial.

recvSelf()

int XC::DruckerPrager::recvSelf ( const Communicator &  comm )

virtual

Receive the object.

Each object has to receive the data needed to be able to recreate itself in the new process after it has been sent through cp. If the object is an aggregation containing other objects, new objects of the correct type can be constructed using #theBroker. To return 0 if successful or a -1 if not.

Implements XC::MovableObject.

sendSelf()

int XC::DruckerPrager::sendSelf ( Communicator &  comm )

virtual

Send the object.

Each object has to send the data needed to be able to reproduce that object in a remote process. The object uses the methods provided by cp object to send the data to another channel at the remote actor, the address of the channel is set before this method is called. An object of similar type at the remote actor is invoked with a receiveSelf() to receive the data. Returns 0 if successful (successful in that the data got to the channel), or a - if no data was sent.

Implements XC::MovableObject.

updateMaterialStage()

void XC::DruckerPrager::updateMaterialStage

(

int

stage

)

Update material stage.

Parameters

stage

0= elastic+no param update; 1= elastic+param update; 2= elastoplastic+no param update (default).
