Abstract: The nonlinear response of shallow shells subjected to combined acoustic and thermal loads is analyzed using an efficient nonlinear modal finite element (FE) formulation. The acoustic loads have nonGaussian probabilistic ...

Abstract: A model of isotropic ductile plastic damage based on a continuum damage variable, on the effective stress concept and on thermodynamics is derived. The damage is linear with equivalent strain ...

Abstract: In this paper, the classical work on steady actuator disk theory is recalled and the interpretation of the flow as the continuous shedding of vortex rings of constant strength that causes the slip stream is shown to be ...

Abstract: A new kind of sounding is described. The relative horizontal wind between a balloon and a gondola located below it, is measured by means of high-resolution anemometers. The integration along the vertical of the relative ...

Abstract: In Israel, a single regulatory body for radiation protection does not exist. Instead, its responsibilities and functions are shared between five government ministries and agencies. Accordingly, the existing legal framework ...

Abstract: To improve the tolerancing process in an industrial context, there exists a strong need for tolerance analysis to estimate the probability of scrap in an acceptable computer time and managing the accuracy of the results. ...

Abstract: observations of waterspouts and tornadoes suggest some influence of surface roughness on these phenomena. In a laboratory model of a tornado-like vortex, this influence is measured in terms of tangential and vertical ...

Abstract: A nonrandomized weather modification project, hail prevention by seeding from the ground, has been run since 1952 in a large area of southwestern France. From the beginning of the experiment, the parameter proposed to ...
