chrono::peridynamics::ChMatterPeri< T_per_node, T_per_bond > Class Template Reference
Description
template<class T_per_node = ChMatterDataPerNode, class T_per_bond = ChMatterDataPerBond>
class chrono::peridynamics::ChMatterPeri< T_per_node, T_per_bond >
Sub-base templated class for assigning material properties (elasticity, viscosity etc) to a cluster of peridynamics nodes.
It must be inherited by classes that define specific materials, and those may optionally use per-edge and per-node data structures by inheriting ChMatterDataPerNode and ChMatterDataPerBond and passing them as template parameters.

Constructor & Destructor Documentation
◆ ChMatterPeri()
template<class T_per_node = ChMatterDataPerNode, class T_per_bond = ChMatterDataPerBond>
|
inline |
Build a cluster of nodes for peridynamics.
By default the cluster will contain 0 particles.
Member Function Documentation
◆ AddProximity()
template<class T_per_node = ChMatterDataPerNode, class T_per_bond = ChMatterDataPerBond>
|
inlineoverridevirtual |
Add a proximity: this will be called thousand of times by the broadphase collision detection.
If the two nodes are of proper type, and if bond not yet present, add a T_per_node structure to this->bonds and return true, otherwise return false.
Implements chrono::peridynamics::ChMatterPeriBase.
◆ ComputeCollisionStateChanges()
template<class T_per_node = ChMatterDataPerNode, class T_per_bond = ChMatterDataPerBond>
|
inlineoverridevirtual |
CONSTITUTIVE MODEL - INTERFACE TO IMPLEMENT: (optionally)
Changes the collision model of nodes, from collision to no collision, etc., ex when an interface is generated, depending on the evolution of the system.
It is run right before the collision detection compute proximyty bonds & contacts. This may add/remove collision models, or may change them. The base behavior is: create collision models when mnode->IsRequiringCollision(), remove if not.
Implements chrono::peridynamics::ChMatterPeriBase.
◆ ComputeForcesReset()
template<class T_per_node = ChMatterDataPerNode, class T_per_bond = ChMatterDataPerBond>
|
inlineoverridevirtual |
CONSTITUTIVE MODEL - INTERFACE TO IMPLEMENT: (optionally) Base behaviour:
- resets the ChNodePeri::F vector of each ChNodePeri to zero.
- adds or remove collision model from the collision engine
- resets is_fluid optimization flag (is not is_fluid, bonds are persistent as an elastic, and collision engine not needed)
