Originální abstrakt

Fracture mechanics and strain energy release rate approach have been widely used for characterizing delamination in composite materials. This paper focuses on extending this approach to delamination at bi-material interface of GRFP and CRFP. Combination of these materials is a common design practice in small aircrafts and enables the utilization of carbon composite materials superior mechanical properties and glass composite lower cost. Modification of FRMM (Fixed Ratio Mixed Mode) testing method was used in order to get critical strain energy release rate in various levels of mixed mode (mode I / mode II). Beam theory analysis with conjunction of VCCT (Virtual Crack Closure Technique) was utilized for establishing equations for previously mentioned test method. Another modification of common testing procedure was application of Aramis photogrammetry system during the measurement of crack tip propagation in a specimen and following image post-processing by Python programming language.
