Kagome plate structures for actuation
A class of planar, pin-jointed truss structures based on the ancient Kagome basket weave pattern with exceptional characteristics for actuation has been identified. Its in-plane stiffness is isotropic and has optimal weight among planar trusses for specified stiffness or strength. The version with welded joints resists plastic yielding and buckling, while storing minimal energy upon truss bendi...
متن کاملOn-Line Corrosion Monitoring of Plate Structures Based on Guided Wave Tomography Using Piezoelectric Sensors
Corrosion is a major safety and economic concern to various industries. In this paper, a novel ultrasonic guided wave tomography (GWT) system based on self-designed piezoelectric sensors is presented for on-line corrosion monitoring of large plate-like structures. Accurate thickness reconstruction of corrosion damages is achieved by using the dispersive regimes of selected guided waves and a re...
متن کاملA Subdivision Scheme Based on Vertex Normals for Triangular Patches
In order to achieve a smooth surface while rendering a triangle-based mesh, we need to eliminate the mismatch between the smoothness of the shading and the non-smoothness of the geometry that is particularly visible at silhouettes. To eliminate these artifacts, we substitute the geometry of a cubic triangular Bézier curved patch for a triangular flat geometry. Meanwhile a subdivision algorithm ...
متن کاملTopologically consistent trimmed surface approximations based on triangular patches
Topologically consistent algorithms for the intersection and trimming of free-form parametric surfaces are of fundamental importance in computer-aided design, analysis, and manufacturing. Since the intersection of (for example) two bicubic tensor-product surface patches is not a rational curve, it is usually described by approximations in the parameter domain of each surface. If these approxima...
متن کاملPlate modes in piezoelectric multilayered structures
2014 Recent experiments have shown that interdigital transducers can couple strongly to plate modes in piezoelectric composite membranes. In this paper the dispersive properties and the piezoelectric coupling (039403BD/03BD) to these plate modes are presented The various types of modes are identified and related to crystalline symmetry. Results are given for stiffened-shear modes in zinc oxide ...
