Description

Cementitious materials such as mortar or concrete are brittle and have an inherent weakness
in resisting tensile stresses. The addition of discontinuous fibers to such matrices leads to a
dramatic improvement in their toughness and remedies their deficiencies. It is generally
agreed that the fibers contribute primarily to the post-cracking response of the composite by
bridging the cracks and providing resistance to crack opening (Suwaka & Fukuyama 2006).
On the other hand, the multifield theory is a mathematical tool able to describe materials
