A Finite Element - Capacitane Method for Elliptic Problems on Regions Partitioned into Subregions.
A numerical method of solution of the static problem for a finite elastic cylindrical shell with general mixed boundary conditions is presented. The existence and uniqueness of the solution of the problem considered is proved first. Then the differential governing equations are discretized by means of the stable and convergent difference schemes. The resultant algebraic equations are solved by an iterative technique requiring the smallest number of arithmetic operations. No particular case is computed....
Consider the following parabolic equation: (1) ∂u/∂t−∑2i=1(d/dxi)ai(x,t,u,D1u,D2u)+a0(x,t,u,D1u,D2u)=f(x,t), x=(x1,x2)∈Ω⊂R2, t∈[0,T], with the initial value condition u(x,0)=u0(x), x∈Ω, and with the boundary value condition u(x,t)=0, x∈∂Ω, t∈[0,T]. For the solution of equation (1) the author proposes a variational-difference method. Namely, he approximates equation (1) by Galerkin's method with respect to the variables x1,x2 and by the finite-difference method with respect to the variable t. Under...
