Multiscale strain investigation of stressed carbon fiber reinforced composites based on data of strain gauging,digital image correlation,acoustic emission

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.
