Special Issue Information

Dear Colleagues,

The Special Issue invites contributions presenting recent developments and state-of-the-art comparison in the area of mechanics of fiber-reinforced cementitious composites, including thermomechanics.

Fiber-reinforced composites have been known for millennia, starting from the straw-reinforced clay that was used for building houses and furnaces. Concrete has also been used for millennia, with its use being introduced widely by the Romans. Despite this, the mechanical properties of fiber-reinforced cementitious composites are still a subject of research which has seen increasing intensity in recent years.

On one hand, fiber-reinforced cementitious composites offer known advantages over more conventional materials, e.g., reduction of shrinkage cracking, increased load-bearing capacity, strain-hardening, and durability under extreme temperatures in fire safety and refractory applications. On the other hand, the dependency of mechanical properties on the spatial and orientational distribution of the fibers poses challenges, both for theoretical calculation as well as for practical manufacturing.

I look forward to your valuable contribution to the Special Issue, which will present new results in this challenging topic.

The present paper proposes a useful closed-form solution for a wide class of mechanical problems, among which one of the most relevant and debated is the deboning process of Fiber-Reinforced Polymer (FRP) strips glued to generic materials and possibly intended as a mode-II fracture process. Specifically, after outlining well-known equations, a novel piecewise analytical formulation based on a cascading solution process is proposed with the aim of keeping the mathematical expressions of the relevant mechanical quantities as simple as possible. Although other analytical solutions and numerical procedures are already available in the literature, the present one is capable of handling the softening or snap-back response deriving from the full-range simulation of the depending process with no need for complex numerical techniques. This is obtained by considering the slip at the free end of the strip as the main displacement control parameter. After some comparisons between the proposed closed-form solution and experimental results available in the literature, some mechanical considerations are highlighted by elaborating on the results of a parametric study considering the variation of the main geometric and mechanical quantities. The numerical code implemented as part of the present study is available to readers in Open Access. Full article

This study presents a non-linear cracked-hinge model for the post-cracking response of fiber-reinforced cementitious composites loaded in bending. The proposed displacement-based model follows a meso-mechanical approach, which makes it possible to consider explicitly the random distribution and orientation of the reinforcing fibers. Moreover, the model allows for considering two different fiber typologies whereas the cement matrix is modelled as a homogeneous material. The proposed mechanical model combines a fracture-based, stress-crack opening relationship for the cementitious matrix with generalized laws aimed to capture the crack-bridging effect played by the reinforcing fibers. These laws are derived by considering both the fiber-to-matrix bond mechanism and fiber anchoring action possibly due to hooked ends. The paper includes a numerical implementation of the proposed theory, which is validated against experimental results dealing with fiber-reinforced cement composites reinforced with different short fibers. The excellent theory vs. experiment matching demonstrates the high technical potential of the presented model, obtained at a reasonable computational cost. Full article
