Thermopiezoelastic snapping of piezolaminated plates using layerwise nonlinear finite elements
No full textThe thermopiezoelastic snapping phenomena of piezolaminated plates are numerically simulated by applying a cylindrical are-length scheme to Newton-Raphson method. Based on the layer,vise displacement theory and von Karman strain-displacement relationships, nonlinear finite element formulations are derived for thermopiezoelastic composite plates. From the static and dynamic viewpoint, nonlinear thermopiezoelastic behavior and vibration characteristics are investigated for symmetric and eccentric structural models with variouspiezoelectric actuation modes, Present results show the possibility to enhance the performance of thermal structures using piezoelectric actuators and report new phenomena, namely thermopiezoelastic snapping, induced by the excessive piezoelectric actuation in the active suppression of thermally buckled large deflection of piezolaminated plates
Postbuckling and vibration characteristics of piezolaminated composite plate subject to thermo-piezoelectric loads
No full textPostbuckling and vibration analyses considering large thermopiezoelastic deflections are performed for fully symmetric and partially eccentric piezolaminated composite plates. Non-linear finite element equations based on the layerwise displacement theory are formulated for piezolaminated plates subject to thermal piezoelectric loads. The results demonstrate a methodology for raising the thermal buckling temperature and decreasing the thermal postbuckled deflection. Vibration characteristics under complex thermopiezoelectric loads are investigated in the prebuckling and postbuckling regions. For fully distributed piezolaminates, this study shows that excessive bending moments for the suppression of thermally buckled deflection may cause another type of structural instability. In addition, the effective placement of piezoceramic patches is studied to improve suppression of thermally buckled deflection for the partially segmented piezolaminates. (C) 2000 Academic Press
Aeroelastic characteristics of cylindrical hybrid composite panels with viscoelastic damping treatments
No full textSupersonic flutter analysis of cylindrical composite panels with structural damping treatments has been performed using the finite element method based on the zig-zag layerwise shell theory. The natural frequencies and loss factors of cylindrical viscoelastic composites are computed considering the effects of transverse shear deformation. And Kumhaar's modified piston theory is applied for the calculation of aerodynamic forces. The flutter of cylindrical composite panels is analyzed considering structural damping effect. With respect to aeroelastic stabilities, various damping characteristics of unconstrained layer, constrained layer, and symmetrically co-cured sandwich laminates are compared with those of an original base panel.

Design Education — The Role of Technology in Reforming Design Education — Pedagogy · Critique · Transformation
Get PDFDesign education has significantly changed since the 1950s. The era depended widely on normative models such as those proposed by Benjamin Bloom (Bloom et al. 1956) and his collaborators, which resulted in the formulation of Bloom's Taxonomy. Comprising six interchangeable layers (knowledge, comprehension, application, analysis, synthesis, and evaluation) of higher and lower thinking, Bloom's taxonomy sets in place an archetypal model for education that thrives on object-driven goals. Here, pedagogical interchange and the object-driven and organised structure of education can adapt to each layer within the taxonomic structure
