Abstract: The stability of steel radial gates used in reservoirs, hydroelectric power stations, etc. is studied by modeling them as rectangular, trapezoidal or triangular frames. The elastic resistance of the rubber seals for ...

Abstract: In this technical note, a finite-element solution of a simply supported beam with variable arc length under a point load is presented. The beam is hinged at one end and simply supported over the other end. The distance ...

Abstract: Critical buckling loads and natural frequencies of lateral vibration modes are determined for a long vertical pipe, suspended in a fluid, simply supported at the top and vertically guided at ...

Abstract: This paper presents stability data for a very long vertical pipe transmitting torque in a viscous medium. In addition to these factors, distributed pipe weight and hydrostatic-fluid pressure ...

Abstract: In some geometrically nonlinear problems, the effects of external loads are altered significantly by the deformations of structures themselves. In finite element analysis, the assumed displacement method is often used to ...

Abstract: This paper presents two methods to find the elastica of a bar or a beam of given span length, but unknown arc length. The beam is subjected to a moment at a hinged end that can slide freely over another support. In the ...

Abstract: A closed shell structured eyeball model was developed for predicting the displacements and curvatures in an eyeball due to radial keratotomy. Both the cornea and sclera are modeled as an ...

Abstract: The natural boundary conditions for corners of a certain type of twodimensional problem are derived from the variational principle. A plate problem formulated by the principle of minimum potential energy belongs to this ...
