Abstract: The N-segment circular arch with rigid members and semirigid joints under external pressure is studied. The problem is formulated in coupled difference equations. An efficient initial value method is presented to solve the ...

Abstract: The Darcy–Brinkman flow through a tapered channel or cone, including the flow through a slit or hole on a plate, is studied for the first time. Assuming small Darcy numbers, the solution is found to third order error using ...

Abstract: Liquid or gas seeps into one side of a porous layer. Coriolis forces affect the flow due to system rotation. The problem models seepage flow into a porous rock fault under planetary rotation. Using similarity, the ...

Abstract: The flow through narrow, arbitrarily curved channels is formulated using intrinsic coordinates. An exact solution exists for constant curvature or circular arc boundaries. A perturbation scheme ...

Abstract: The laminar, viscous flow between parallel plates with evenly spaced longitudinal ribs is solved by an eigenfunction expansion and point-match method. The ribs on both plates may be symmetrically ...

Abstract: The buckling of a column, clamped at both ends and with an interior hinge is studied. It is shown that the buckling load of a column with an interior hinge depends on the location of the hinge. The optimum location of a ...

Abstract: Melting of a disk is facilitated by rotation. The problem is governed by a nondimensional parameter α which represents the relative importance of injection (melt) rate and rotation times ...
