The active vibration control of a composite plate using discrete piezoelectric patches has been investigated. Based on first order shear deformation theory, finite element model with the contributions sensor and actuator to mass stiffness was used derive state space equation. A global optimization based LQR performance is developed find optimal location patches. Genetic algorithm adopted implemented evaluate configuration. provides damping effect by means algorithm. correlation between...
In this paper, machining aeronautical aluminum alloy AA2024-T351 in dry conditions was investigated. Cutting forces, chip segmentation, and built-up edge formation were analyzed. Machining tests revealed that the process depends on cutting tool geometry. So continuous segmented chips are generated. Under some conditions, occurs. A predictive theory, based a finite elements method (FEM), applied to reproduce explain these phenomena. Thermomechanical behaviors of work material tool-work...
Titanium and its alloys are often used in aerospace, power biomedical applications due to their low density, high tensile strength, resistance corrosion temperatures. However, these materials well known be difficult-to-cut require follow some special techniques improve machinability. It should also noticed that phenomena like segmentation recrystallization can occur during the chip formation process. Therefore, fine grains observed adiabatic shear bands located segments. The machined surface...
This paper deals with analysis of the cutting process, on a macro and micro scale, in deep hole drilling BTA system. An experimental procedure is developed to highlight impact speed feed rate process when machining 18MND5 steel. Parameters based dimensional characteristics chips are introduced quantify morphology generated by central, intermediate external inserts complex tool. From observation (flat, curved spiral) measurement width, provenance each chip respect identified. Then, Chip...
Titanium alloys are considered difficult-to-cut materials due to their low machinability. Understanding the physical mechanisms occurring during cutting titanium is of particular interest improve Experimental and numerical investigations on Ti-6Al-4V alloy machining proposed in this paper. Orthogonal tests performed. The chip microstructure characterized using SEM observations coupled with EBSD technique reveal deformation inside microstructure. Based these microscale observations, a new...
This study investigates the morphological changes and tensile properties of Alfa fibers extracted mechanically after two treatments namely water retting alkali treatment.
