Investigation of Mode I Delamination Resistance in Inter-ply and Intra-ply Hybrid Composites Reinforced with Basalt/Nylon Woven Fabrics
Due to their sensitivity to impact-induced delamination, woven fabric reinforced polymer composites have limited practical applications. Hybridization of polymer composites has been proposed as a solution to this problem. In this study, the effects of fiber reinforcement type, hybridization method, plies stacking sequence and loading rate on mode I delamination behavior of pure basalt, pure nyl...
متن کاملRespiratory-Gated Continuously Moving Table 3D MRI
B. Aldefeld, P. Börnert, J. Keupp, K. Nehrke Philips Research Laboratories, Hamburg, Germany Introduction When continuously moving table imaging is applied to an extended virtual FOV that includes the abdomen and chest, the physiological motion of the patient must be addressed to achieve optimum image quality. Scanning under breath-hold conditions is unacceptable in most cases because scan time...
متن کاملDesign and Experimental Investigation of a 2-DOF Planar Micro-Positioning Table
This paper presents the mechanical design and experimental characterization of a 2-DOF serial flexurebased micropositioning table. The cascade mechanical structure is proposed to implement planar motions of the moving platform. In order to increase the stroke of the moving platform, a lever mechanism is designed to amplify the displacement of the piezoelectric actuator. The finite element metho...
متن کاملTwo-ply brain barrier
Arthritic joints are chock-full of activated immune cells. These cells produce chemotactic proteins that lure other cells into the joint, setting up a vicious cycle of inflammation. But what instigates this cycle in the first place? A study by Kim et al. (page 829) puts much of the blame on neutrophils. Neutrophils—granular cells that are among the immune system’s earliest responders during inf...
متن کاملIntra-ply shear locking
Intra-ply shear locking results in unrealistic fibre stresses and spurious wrinkling in composite forming simulations. Three remedies are investigated: aligning the mesh, applying reduced integration and using multi-field elements. The bias extension simulation is used to test several triangular and quadrilateral elements on their capability to avoid locking. Their performance under large defor...
