chrono::peridynamics::ChMatterPeriSprings Class Reference
Description
The simplest peridynamic material: a bond-based material based on a network of springs, each with the same stiffness k regardless of length, etc.
Just for didactical purposes - do not use it for serious applications. Also use a damping coefficient r.

CONSTITUTIVE MODEL - INTERFACE TO IMPLEMENT: IMPORTANT Add the forces caused by this material to the ChNodePeri::F vector of each ChNodePeri.
Child class can use the containers this->nodes and this->bonds to compute F, assuming bonds have been updated with latest collision detection.
Implements chrono::peridynamics::ChMatterPeriBase.
The documentation for this class was generated from the following file:
