One of the fundamental aspects in cohesive zone modeling is the definition of the traction-
separation relationship across fracture surfaces, which approximates the nonlinear fracture …

A potential-based cohesive zone model, so called the PPR model, is implemented in a
commercial software, eg ABAQUS, as a user-defined element (UEL) subroutine. The …

Three–dimensional nonlinear finite–element models have been developed to investigate
the loading–unloading–reloading behaviour of two reinforced–concrete beams under four …

This paper presents the experimental and numerical studies of flexural-fracture behaviors of
steel fiber–reinforced rubber self-compacting concrete (SRSCC) materials. The scrap-tires …

Recent progresses in nanotechnology have clearly shown that the incorporation of
nanomaterials within concrete elements leads to a sensible increase in strength and …

A simple, effective, and practical constitutive model for cohesive fracture of fiber reinforced
concrete is proposed by differentiating the aggregate bridging zone and the fiber bridging …

The design of structures with a nonuniform stress field is of great industrial interest. The
ability of the size effect law and critical distance theories to predict the nominal strength of …

The influence of aggregate shape on the fracture energy, tensile strength and elasticity
modulus in concrete is considered. For this purpose, eight simple cement-based composites …

A new damage model is proposed in the bond-based peridynamics (BBPD) frame to
quantitatively investigate mode-I crack propagation in concrete, which is established based …

This study presents experimental and numerical research on the in-plane behavior of
unreinforced confined masonry walls retrofitted using engineered cementitious composite …
