Detailed Description

This class implements a FRCFCM material (Fiber Reinforced Concrete base on Fixed Crack Model) in a finite element problem. This class provides an extension to the ConcreteFCM which serves as a material model for matrix while the present class FRCFCM adds the contribution of fibers. The contribution of the two constituents are defined by Vf parameter = volume of fibers.
