The finite element simulations for the corresponding coatings with a series of thicknesses were carried out by introducing the interface cohesive model, and the simulations show results similar to those of the experimental observations.
The results of the finite element cohesive zone model simulation indicate that the interface crack of the asphalt mixture was mainly effected by critical stress, interface angle of inclination, interface length, and interface location.
From the computational point of view, the evolution of the crack pattern is modeled as a stochastic process via finite element based cohesive zone simulations.
These interface elements which connect the three-dimensional solid elements modeling the composite layers, include a cohesive damage model allowing the simulation of delamination initiation and propagation.
The model was validated numerically by means of a bilinear cohesive damage model which allows the simulation of damage initiation and growth.
DCB and ENF mechanical test results from a previous work of some of the authors are used as reference for the identification of cohesive zone model by numerical simulations with the finite element software Abaqus using implicit time integration.
Subsequently, crack propagation simulations using a hysteretic cohesive zone model are performed for parametric combinations which initiate top coat cracks.
A semi-automatic system for cohesive sediment transport simulation has been established by preparing the essential data base, and also by integrating various components of coastal models including those for waves, tide, storm surge and wave-induced circulation, from which various processes in cohesive sediment transport are numerically modeled.
Moreover, numerical simulations are performed based on the cohesive zone model to verify the experimental results.
Simulations reported in the present work use irreversible cohesive zone model and are based on experimental data for a Nickel-based superalloy.
