RESEARCH ON RANDOM VIBRATION FATIGUE OF THIN-WALLED STIFFENED STRUCTURES

“…In order to investigate the vibration fatigue characteristics of thin-walled stiffened structures under random vibration loading,a random vibration test was carried out.The structure inherent frequency and modal response were obtained by using the hammering and the sine-sweep method,the cracking time and pattern were recorded.The method for obtaining the fatigue life curve under random stress by revising the fatigue life curve under equal amplitude stress was deduced.Then based on MSC/Patran&Nastran simulation finite-element software,the dynamic response on the fatigue danger point and its random vibration fatigue life were obtained,the effects of creating model methods on the inherent frequency were studied,and the change of damping impacts on the vibration properties was analyzed.The results show that the model stiffness with using mixed element are much closer to the actual structure than only solid or shell,the modal responses under the nonlinear damping are more consistent with the sweep results.Finally,the calculated fatigue life and failure position are in good agreement with the experimental results.…”

A new similitude law for testing scaled RC structures by Jamin Park, Seong-Cheol Lee, Yunbyeong Chae, Jae-Yeol Cho

“…Abstract In a scaled model test for reinforced concrete (RC) structures, the stress-strain relationship of the concrete of the scaled model is often quite different from that of ordinary concrete which is used for the prototype, while that of the reinforcement is typically the same for both the prototype and scaled model. …”

Augmenting the Structures in a Swirling Flame via Diffusive Injection by Jonathan Lewis, Agustin Valera-Medina, Richard Marsh, Steven Morris

“…Small scale experimentation using particle image velocimetry investigated the effect of the diffusive injection of methane, air, and carbon dioxide on the coherent structures in a swirling flame. The interaction between the high momentum flow region (HMFR) and central recirculation zone (CRZ) of the flame is a potential cause of combustion induced vortex breakdown (CIVB) and occurs when the HMFR squeezes the CRZ, resulting in upstream propagation. …”
