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 …
We present a phase field formulation for fracture in functionally graded materials (FGMs). The model builds upon homogenization theory and accounts for the spatial variation of …
This is a practical paper which consists of investigating fracture behavior in asphalt concrete using an intrinsic cohesive zone model (CZM). The separation and traction response along …

This work investigates dynamic failure processes in homogeneous and functionally graded materials (FGMs). The failure criterion is incorporated in the cohesive zone model (CZM) …
Mechanics of Functionally Graded Material Structures is an authoritative and fresh look at various functionally graded materials, customizing them with various structures. The book is …
We present a novel particle-based computational framework for the numerical simulation of dynamic crack propagation in functionally graded materials under highly dynamic loading …

The two-dimensional functionally graded materials,(2D-FGMs) have been recently introduced in order to significantly reduce the thermal stresses in machine elements that …
A new interfacial cracking model in the phase field framework is proposed. The developed method is able to capture the effects of both stiff and soft interphases on the fracture …
