OPTIMAL DESIGN OF SHELLS WITH STEP-FUNCTION DISTRIBUTION OF THICKNESS
The paper is concerned with a methodology of optimal design of shells of minimum weight with strength, stability and strain constraints. Stress and strain state of the shell is determined by Galerkin method in the mixed finite element formulation within the geometrically nonlinear theory. The analysis of the effectiveness of different optimization algorithms to solve the set problem is given. T...

متن کاملOptimal thickness distributions of aeroelastic flapping shells
Optimal thickness distributions of aeroelastic flapping shells" (2013). a r t i c l e i n f o a b s t r a c t The severe weight limitations of flapping wing micro air vehicles necessitates the use of thin flexible wings, which in turn requires an aeroelastic modeling tool for proper numerical characterization. Furthermore, due to the unconventional nature of these vehicles, wing design guidelin...
متن کاملStress Analysis of Rotating Thick Truncated Conical Shells with Variable Thickness under Mechanical and Thermal Loads
In this paper, thermo-elastic analysis of a rotating thick truncated conical shell subjected to the temperature gradient, internal pressure and external pressure is presented. Given the existence of shear stress in the conical shell due to thickness change along the axial direction, the governing equations are obtained based on first-order shear deformation theory (FSDT). These equations are so...
متن کاملMan with Abdominal Distension
CASE A 63-year-old man presented with abdominal distension and shortness of breath for two days. He reported flatus and denied chest pain, anorexia, vomiting, or abdominal pain. Surgical history was notable for left hepatectomy, cholecystectomy and choledochojejunostomy with a Rouxen-Y. He was afebrile with a pulse in the 100s, blood pressure of 130/60, respiratory rate of 34, and oxygen satura...
