Automated tool for simulation of standardized tests of cohesive interfaces

Original language description

This work deals with determination of material parameters of cohesive interface using finite element models. Cohesive interface means conjunction of two deformable materials with relatively high stiffness compared to the interface. This conjunction or adhesive bonding determines overall strength of this system for certain loading types. In general, failure of such interface is caused by normal and shear stresses. Resulting failure is in fact a case of the crack growth and can be determined by parameters used in fracture mechanics. Strain energy release rate (SERR) G was selected as a basic parameter for evaluation of cohesive interface failure for this reason. Numerical analyses are performed in FE software Abaqus 6.14. Automated tool for identification of material parameters of two of the mentioned basic modes was created using Python 2.7. programing language. Material parameters of two adhesives, Hunstman Araldite 2021 and Gurit Spabond 345, and an inner layer of laminated composite are identified through secondary material parameters: stiffness k, displacement δ 0 (damage initiation) and δ c (failure determination).
