Experimental studies and modelling of fracture toughness of the epoxy samples with eccentric cracks

The relevance of the work is due to the need for experimental studies to determine the mechanical characteristics of epoxy resin samples, which can be used to check the correctness of the choice of parameters and criteria for the onset of crack growth within the framework of elastic fracture mechanics, cohesive models, models such as virtual crack closure technique, extended finite element method, etc. Thus, the article is aimed at determining...
