METHOD OF DETERMINING FATIGUE FAILURE OF STRUCTURAL ELEMENTS MADE OF POLYMER COMPOSITE MATERIAL

摘要

FIELD: fault detection.;SUBSTANCE: invention relates to the field of monitoring the state of a structure in terms of strength conditions, aimed at determining the breaking point of structural elements made of polymer composite material (PCM) under cyclic loading. Method consists in controlling the thickening in the zone of potential destruction of the structural member. In addition, the linear thickening of the element in the fracture zone is measured, the failure is fixed at the time of reaching a thickness value of 0.7 % of the thickness of the element in the fracture zone.;EFFECT: increase in the accuracy of determining the design characteristics of fatigue resistance of structural elements from PCM.;3 cl, 2 dwg
