چکیده
This paper describes how to compute equations of plane models of minimal Du Val double planes of general type with pg = q = 1 and K2 = 2, . . . , 8. A double plane with K2 = 8 having bicanonical map not composed with the associated involution is also constructed. The computations are done using the algebra system Magma.

متن کاملCracked piezoelectric layer bounded between two orthotropic half-planes
This paper deals with the behavior of anti-plane shear crack in a piezoelectric layer bounded between two orthotropic half-planes within the framework of linear electroelasticity. The crack surfaces are assumed to be permeable or impermeable. The analysis is based on the stress fields caused by Volterra-type screw dislocation in the medium. Fourier transforms are used to reduce the dislocation ...
متن کاملSolving high-order partial differential equations in unbounded domains by means of double exponential second kind Chebyshev approximation
In this paper, a collocation method for solving high-order linear partial differential equations (PDEs) with variable coefficients under more general form of conditions is presented. This method is based on the approximation of the truncated double exponential second kind Chebyshev (ESC) series. The definition of the partial derivative is presented and derived as new operational matrices of der...
متن کاملApplication of the multi-laminate sub-loading surface model in the simulation of a pipe-jacking operation
In this paper a constitutive model formulated in the framework of multi-laminate models is applied to analyze pipe-jacking processes. The multi-laminate -based models consider various integration planes to formulate the stress-strain relationship. This basic feature of the framework has the advantage that yield criteria, flow and hardening rules are formulated on planes rather than in three-dim...
متن کاملThermal Effect on the Torsional Buckling of Double Walled Carbon Nanotube Embedded in Pasternak Foundation
In this study the effect of thermal stress on the torsional buckling of double walled carbon nanotubes is investigated. Moreover based on nonlocal continuum mechanic the buckling governing equations are obtained and equilibrium of Equations is generalized to double wall nanotubes. Also in this study the elastic medium, small scale effect and van der Walls force are considered. Also for simulati...
