The design of thin-walled cylinders in axial compression is limited by sensitivity to geometric imperfections. This paper focuses on reducing this imperfection from a perspective. By using variable-angle composites, the load paths are tailored reduce effective area over which imperfections can initiate buckling. Continuous Tow Shearing (CTS) one such manufacturing technique. It does not cause d...

This article provides a fully analytical approach for nonlinear equilibrium path of rectangular sandwich plates. The core of structure is made of symmetric cross-ply laminated composite and the outer surfaces are piezoelectric actuators which perfectly bonded to inner core. The structure is subjected to electro-thermo-mechanical loads simultaneously. One side of plate is rested on Pasternak typ...

The structural fire response of slender austenitic stainless steel I-sections in weak-axis flexure is studied experimentally for the first time. presented experimental programme comprised local geometric imperfection measurements all test beams, room temperature material tests, a reference bending and series elevated tests. setup, procedure measured responses specimens are fully described. resu...

A UNA RIFLESSIONE TEORICA FONDANTE RIFERITA AL TERMINE IXD, E NON AVREBBE TUTTI I TORTI. QUELLO DI FAR EVOLVERE LE COSE NATURALMENTE È UN ATTEGGIAMENTO MOLTO PRAGMATICO, DI ESTREMA EFFICACIA QUANDO SI HA A CHE FARE CON L'EMERGERE DI UN NUOVO SETTORE. OGGI PERÒ L'IXD PUÒ CONTARE SU UNA DISCRETA FIDELIZZAZIONE, SU ALCUNE SCUOLE DI FORMAZIONE E SULL'APPORTO DI "ADEPTI" PROVENIENTI DA NUMEROSE DISC...

The precision of image synthesis techniques for rendering naturalistic scenes often works contrary to the realism of the everyday world. Pristine, crystalline, uniform and perfect may describe the most idealized computer images: the surfaces are smooth, neat and crisp in appearance. Efforts to produce realism have recently focused on light and the interaction of light with surfaces. The radiosi...

PANDA2, a computer program for the minimum-weight design of elastic perfect and imperfect stiffened cylindrical panels and shells under multiple sets of combined loads, is used to obtain optimum designs of uniformly axially compressed elastic internal T-ring and external T-stringer stiffened cylindrical shells with initial imperfections in the form of the general buckling mode. The optimum desi...

In Chapter 1, we seek to understand the relation between liquidity and market imperfections from two dimensions: 1) Across liquidity measures, we compare the influence of imperfections on two commonly used measures, Kyle's lambda and price reversal; 2) Across imperfections, we study the interaction between two sources of market imperfection, information asymmetry and participation cost. We show...
