The stress
distribution in the matrix and the fiber in the region of a fiber break
is illustrated.
The interfacial shear stress between the fiber and
the matrix is a maximum at the break and decreases to zero over the transfer
length for the system.
The tensile stress in the fiber is zero at the
break, increases to its maximum value over the transfer length, and remains constant
over the region of the fiber in the isostrain state.
