Fiber-reinforced cementitious matrix (FRCM) composites are usually mechanically characterized by means of tensile and bond tests. The load responses provided by tensile tests are typically comprised of three phases, namely the uncracked, cracking, and fully cracked phase. The uncracked phase ends when the applied stress attains the matrix tensile strength. During the cracking phase, multiple cracks form in the matrix and the behavior of the speci-mens is governed by the shear stress acting at the fiber-matrix interface. During the fully cracked phase the width of the cracks increases and the applied load is carried by the textile in the cracked cross-sections.
