چکیده
Summ~ry--A method is developed for representing the tangential displacements and tractions at the surface of the semi-infinite solid in terms of potential functions. In this form, a mathematical analogy is revealed between corresponding mixed boundary value problems involving tangential and normal surface displacements respectively. This analogy enables a general solution to be obtained to the problem in which the surface tangential displacements are specified axisymmetrie functions inside the circle a i> r>~ 0 and the tangential surface traction is zero outside this circle. The method can also be used for certain non-axisymmetric problems, but it fails if the indentation analogue has a stress singularity at the boundary of the stressed are~.

Calculating with Procedure Calls
Although various proof rules for procedure calls in weakest precondition semantics have been proposed over the years [3, chapter 12] [4] [1], none of these is particularly suitable for calculational program construction. The problem is that they tend to yield a precondition that is tortuously expressed. For instance, let a procedure for finding the integer square root of a parameter y be specif...

We show that the problem of nding a maximum renamable Horn problem within a propositional satis ability problem is NP hard but can be formulated as a set packing and therefore a maximum clique problem for which numerous algorithms and heuristics have been developed
متن کاملRings characterized by their fuzzy submodules
The notions of pure ideals and pure submodules play an important role in the study of rings and their module categories. In this paper, we introduce right t-pure fuzzy ideals and pure fuzzy submodules of an R-module. We establish their basic properties, and use them to obtain fuzzy theoretic characterizations of right weakly regular rings. Among other results, we prove that a ring R is right we...

Sumlnary--A method is described for finding the normal displacements of the surface of a semi-infinite solid, subjected to arbitrary, transient surface heating. Analytical expressions are derived for the displacements due to instantaneous and continuous point and line heat sources and these can be integrated to produce the solutions to particular problems. The method is illustrated by applicati...

-A long circular cylinder with radius R and thickness t transmits a longitudinal eccentrically applied force to a rigid half-space. We study the influence of the eccentricity of the load and the ratio R/t on the stress state of the cylinder using the theory of thin shells in bending. The elastic displacements are presented in the form of a Fourier expansion, the coefficients of which are found ...
