تجزیه و تحلیل شکست کامپوزیت لاستیک تحت بارگذاری پویا تحت تاثیر رگرسیون لجستیک

The main objective of the present article is the monitoring of damage to rubber composite materials, particularly in the process of impact loading. Test samples were extracted from conveyor belts of the same type (the same structure) and characterised four various phases of the conveyor belt life cycle (new, stored, worn, renovated). Other input parameters were also changed in laboratory conditions: a drop height and a type of material falling onto a test sample, represented by various impactors of a falling drop hammer. The analysis of the test samples damage significance was carried out while applying the logistic regression method. The result is the estimate of the odds ratio of significant damage to a test sample for individual input variables.
