A nonlinear-optimal control strategy is devised using Hamilton-Jacobi formulation for tracking attitude maneuvers of rigid- asymmetric spacecraft. The exact motion model employs kinematical representation by the modified Rodrigues parameters (MRP) large principal rotations. For a constant trajectory, an infinite-horizon optimal problem posed, wherein nonlinear feedforward and feedback torques minimize performance index with quadratic cost fourth-order angular-velocity error cost. Closed-form...
Segmented chips are known to form in machining of titanium alloys due localization heat the shear zone, which is a function environment. To investigate correlation between environments and microstructural aspects chip segmentation, orthogonal turning experiments were performed under three environments, viz., room, LN2, 260 °C. Scanning electron optical microscopy roots show that mechanism segment formation changes from plastic strain mode II fracture at room temperature, predominant I LN2...
Abstract Additive manufacturing of continuous fiber‐based polymeric composites has attracted global attention. This contemporary technology enables the flexibility customized, partially and fully functional, advanced composite components for numerous semi‐structural structural applications. The current study investigates performance 3D‐printed carbon in context tensile, flexural, high‐cycle fatigue. crucial S‐N curves unidirectional (UD) (0°) cross‐ply (CP) (0, 90) have been plotted....
Conventional Fiber-reinforced cementitious matrix (FRCM) systems are prone to fiber-matrix debonding and fiber-fiber debonding, resulting in underutilization of fabric capacity increased costs. The is impregnated with epoxy address slip. However, the coating stiffens fabric, rendering it unsuitable for curved surfaces exacerbating debonding. To tackle these challenges, this study combines an pre-impregnation strategy bendability a mechanical anchorage system mitigate This method locks...
Chip segmentation due to shear localization during machining of titanium alloys affects cutting forces and their machinability. Despite several studies on modeling understanding influence chip segmentation, little is known about the effect preheating it. This work therefore, involves orthogonal Ti6Al4V alloy under between 100 °C 350 investigate band configuration, microstructure machined surfaces, through optical scanning electron microscopy chips roots. Conceptual models segment formation...
