The high specificity of the positive PCL line support the diagnosis of ACL tear. The smaller of the PCL angle and the PCL index, the more possibility of ACL tears.

First of all, on the base of different FEA models of the contact line support frame in the environment of ANSYS, this thesis, according to different working conditions, undertakes static analysis, theoretic mode analysis, harmonic reponse analysis and transient dynamic analysis.

Since the model built is representative, the analysis result can be referred as the theoretic support for the tiredness evaluation of the contact line support frame.

Our data for this line support a two-dimensional model in which horizontal thermal fluctuations of order ±800 K occur in the region τ5000 ≈ 10-3-10-2.

In this paper exact, analytical solutions are derived for another highly popular benchmark problem, namely, L-shaped domains having a horizontal line support and one or several point loads.

The displacement fields vanish along a straight segment of a line support and are constructed within an infinite domain bounded by two half-lines.

The present paper is the first part of the four-part work on Michell cantilevers transmitting a given point load to a given segment of a straight-line support, the feasible domain being a part of the half-plane contained between two fixed half-lines.

Since the method avoids any discretization, the problems associated with the need to move the nodal points so as to coincide with the internal line support are eliminated.

In this paper, the problem for the determination of stress and deflection of a continuous orthogonal anisotropic rectangular plate has been solved, the plate being acted on by uniformly distributed load and being simply supported on all edges and on all intermediate line supports parallel to edges. The key to the solution is the derivation of an important formula which establishes a relation between any three unknown distributed moments of the plate at neighboring line supports and thus may...

In this paper, the problem for the determination of stress and deflection of a continuous orthogonal anisotropic rectangular plate has been solved, the plate being acted on by uniformly distributed load and being simply supported on all edges and on all intermediate line supports parallel to edges. The key to the solution is the derivation of an important formula which establishes a relation between any three unknown distributed moments of the plate at neighboring line supports and thus may be called "three line-supports moment equation”. The method of derivation of this formula is first to solve the problem for the determination of stress and deflection of a single orthogonal anisotropic rectangular plate subjected to distributed moment on edges, then to use the result of analysis of a single orthogonal anisotropic rectangular plate subjected to uniformly distributed load, and finally by the use of condition of continuty of the continuous plate which procedure yields the "three line-supports moment equation”. By the use of this“three line-supports moment equation”the known distributed moments of the plate along all line-supports may be calculated. And the stress or deflection at any point of the continuous orthogonal anisotropic rectangular plate may be obtained by superposition. During the procedure of analysis the M. Levy's method for expressing the general deflection of elastic plate has been used, which method furnishes a good convergency of the infinite series.

This paper introduces a method for sorting vertical interpenetrating holes and its regulation, also introduces its programming method and character for computer auto-processing its intersecting lines supported by Autolisp.

The characteristic impedance of rectangular coaxial transmission lines supporting TEM modes is calculated by using multi-grid method with V-cycle and W-cycle.

The characteristic impedance of rectangular coaxial transmission lines supporting TEM modes is calculated by using multi-grid method with V-cycle and W-cycle. The results are compared with those got from conformal transformation techniques. It verifies the validity of multi-grid method in solving such problems. Then the characteristic impedance of partially dielectric loaded rectangular coaxial transmission lines is calculated by this method. Numerical results show that the multi—grid method with W-cycle is faster about four time than the G-Siterative method.
