Application of optical and acoustic methods for strain investigation of carbon fiber reinforced composite

摘要：

　　A combined method for investigation of localized deformation processes in carbon fiber reinforced composite specimens is applied in order to reveal characteristic stages of strain and fracture.Stress concentrators have the shape of a circular hole and edge crack of various sizes.Use of simultaneous strain data registration has allowed us to register and compare parameters under analysis during entire time of the experiments.The reasons of similarity and difference of the results are shown and discussed.It is offered to apply the obtained results for the aims of non-destructive testing of structural materials being based on revealing characteristic stages of strain development and a particularly prefracture stage.
