Performance Index of Natural Stones-GFRP Hybrid Structures

Luca Sorrentino, Costanzo Bellini, Wilma Polini, Sandro Turchetta

Natural stone is a material that presents durableness over time and high aesthetic characteristic, but it is brittle and its tensile strength is significantly lower than compressive one: these peculiarities must be taken into account for…

Three-dimensional effects on cracked components under anti-plane loading

F. Berto, A. Campagnolo

The existence of three-dimensional effects at cracks has been known for many years, but understanding has been limited, and for some situations still is. Understanding improved when the existence of corner point singularities and their…
