| Abstract: | Stress nearly the crack tipF12organic fiber/epoxy matris of composite with crask is investigated by CTS specimen testing. The principle of the test method, procedure,loading and data processing are presented. A numerical analysis to thc specimen by discontinuous displacement method is carried out. The tested results and numerically calculated ones are approximate each other. |
