Ultrasonic burnishing is one of several surface treatment methods. The method a relatively new process used for finishing workpieces to produce good quality. This paper presents ultrasonic as mechanical improving the quality planar plates. improves by increasing hardness workpiece and reducing its roughness. However, it essential know effect on residual stresses in material. study investigated ...

An integrated sensor system that continuously monitors the structural integrity of an aircraft’s critical composite components can have a high payoff by reducing risks, costs, inspections, and unscheduled maintenance, while increasing safety. Hybrid sensor networks combine or fuse different types of sensors. Fiber Bragg Grating (FBG) sensors can be inserted in layers of composite structures to ...

We have previously demonstrated that it is possible to fabricate densely-packed high aspect ratio structures in SU-8 by means of a top-plate support member which stiffens the overall structure and prevents pattern collapse. In this work we have computed the tensile stresses induced in the top-plate structures due to the capillary forces that arise between the columns due to the surface tension ...
