STUDY ON CRACK PROPAGATION RATE UNDER FATIGUE LOAD
In this article,the new manifestation of crack propagation rate formula has been mainly studied when fatigue loads with diverse stress ratio and frequency acting on component with cracks. Linear and elastic crack propagation rate under fatigue loads with diverse stress ratio and frequency has been c...

| description | In this article,the new manifestation of crack propagation rate formula has been mainly studied when fatigue loads with diverse stress ratio and frequency acting on component with cracks. Linear and elastic crack propagation rate under fatigue loads with diverse stress ratio and frequency has been calculated quantificationally and accurately by modifying new crack propagation rate formula. Scope of application of modifying new crack propagation rate formula has been summarized where the effects of applied fatigue stresses,stress intensity factor transformation amplitudes at the fatigue crack tip are taken into considerations,accuracy and practicability of modifying new crack propagation rate formula having been tested. |
