in this study, behavior of pin-loaded glass fiber reinforced with polyethylene laminated composites with different stacking sequence and different dimensions has been observed experimentally and stress analysis was performed using ansys software. the aim is to investigate stresses, failure strength and failure mode of composite laminates containing a pin loaded hole when the material exhibits l...

This article presents the static performance of composite steering knuckle due to drive on an equivalent road, including different types roughness and maneuvers. To achieve this purpose, driving a full-vehicle model was simulated using multi-body dynamics (MBD) method, imposed loads connection points components suspension system were extracted considering various Next, CATIA software used prepa...

Ultrasonic imaging is a powerful nondestructive evaluation (NDE) tool for flaw characterization. This thesis discusses the signal processing techniques developed for ultrasonic imaging of flaws in composite laminates. Commonly used time-domain signal processing techniques have problems including poor resolution, dependence on operator's experiences and subjectivity. Some transform-domain proces...

Abstract The present work aimed to develop a semi-empirical criterion able describe impact events on GFRP and CFRP (glass carbon fiber reinforced polymers) composite thin laminates: these are generate large damages involving multiple mechanisms such as matrix cracking, failure and, above all, delamination. Main purpose of this research was obtain an accurate numerical description the region in ...

In the current study, the failure behavior of retrofitted steel structures was studied experimentally and theoretically with steel/CFRP double strap joints (DSJs) under quasi-static tensile loading. A series of DSJs with different bonding lengths are also considered and examined to experimentally assess the effective bond length. To predict the failure load values of the tested specimens, a new...

Fred grew up in California and studied biology and played the violin at Princeton as an undergraduate. He obtained an M.D. Ph.D. at UCSF, studying under the wise tutelage of the late Ira Herskowitz. As a graduate student, he played with budding yeast ‘shmoos’ and studied how yeast pheromones arrest the cell cycle. He then went to do postdoctoral stints with Paul Nurse in Oxford and London, and ...

Abstract The presence of open holes changes the behaviour composite laminates when subjected to mechanical loads creating critical zones with a high probability interlaminar and intralaminar damage initiation. While in are requirement many situations such as assembly needs, wiring, maintenance access, their influence on impact response is still poorly understood. In this paper, numerical study ...
