Axially compressed circular cylindrical shells with large diameter-to-thickness ratios are highly susceptible to local buckling, and their load-carrying capacities known be very sensitive initial geometric imperfections. Hence, severe knock-down factors on theoretical buckling loads typically prescribed in design specifications, which greatly impair structural efficiency. With the aim of enhanc...

Initial geometric imperfections have been identified as the main cause for large discrepancies between experimental and theoretical buckling loads of thin-walled circular cylindrical shells under axial compression. The extreme sensitivity to has previously addressed mitigated through introduction stiffeners; however, still remains. Optimized corrugated are largely insensitive hence exhibit exce...

In this paper, stress and strain equations are developed for the left ventricle mainly to nd the innuence of the ventricle's shape on wall stresses. Here, the ventricle is assumed to be a thick-walled truncated conical shell and large elastic deformation theory is applied. Our model is compared to corresponding results approximating the left ventricle as a spherical shell. Clinically relevant p...

Presented a re methods that avoid the need to em ploy an extrapolation technique in the region of the criti ca l points for evaluation of the apparent e mmissivity of diffuse cylindrical and conical cavities. The methods involve appropriate s ubstitutions in the integrands of integral equations that are used in a nalytical so lut ions for determ ining the therm al radiation characteri sti cs of...

We construct flat metrics in a given conformal class with prescribed singularities of real orders at marked points of a closed real surface. The singularities can be small conical, cylindrical, and large conical with possible translation component. Along these lines we give an elementary proof of the uniformization theorem for the sphere. 1. Uniformization in genus 0 and holomorphic structures ...
