It is of great practical importance to analyze the shakedown of shell structures undercyclic loading,especially of those made of strain hardening matericls.In t
This paper describes a way of solving the reservoir simulation pressure equation using multigrid technique.The subroutine MG of four-grid method is presented.Th
In this paper,on the basis of experimental data of two kinds of chemical explosions,the piston-pushing model of spherical blast-waves and the second-order Godun
There are N domains D<sub>j</sub>.(j=0,1,……,N-1 )of different physical parameters in the whole space and their interfaces.S<sub>jj+1</sub>are non-horizontally s
In this paper,the large deflection theory is adopted to analyse the geometrical nonlinear stability of a sandwich shallow cylindrical panel with orthoiropic sur
Using Beltrami-Schaefer stress function in the theory of elasticity in this paper,we derive the stress functions of torsion,plane problem,axisymmetric deformati
