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 …

Interphase regions that form in heterogeneous materials through various underlying
mechanisms such as poor mechanical or chemical adherence, roughness, and coating, play …

Fracture and Size Effect in Concrete and Other Quasibrittle Materials is the first in-depth text
on the application of fracture mechanics to the analysis of failure in concrete structures. The …

The extended finite element method allows one to model displacement discontinuities which
do not conform to interelement surfaces. This method is applied to modeling growth of …

Fracture is one of the pressing issues in modeling civil engineering materials like con crete,
mortar, brick, rock and clay. The pursuit of genuine fracture properties has posed a …

Despite tremendous advances made in fracture mechanics of concrete in recent years, very
little information has been available on the nature of fracture processes and on reliable test …

An extended finite element method scheme for a static cohesive crack is developed with a
new formulation for elements containing crack tips. This method can treat arbitrary cracks …

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 …

The earliest applications of the finite element method to concrete structures included crack
modeling [1–3]. Such modeling, then and now, can be completely characterized by two …

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 …
