THE STROH FORMALISM AND CERTAIN INVARIANCES IN TWO-DIMESIONAL ANISOTROPIC ELASTICITY
1992, 22(2): 145-160. doi: 10.6052/1000-0992-1992-2-J1992-016
Abstract(2350) PDF(755)
Abstract:
The Stroh formalism for two-dimensional deformations of an aniso-tropic elastic body is reviewed briefly. The formalism is mathematically elegant and technically powerful. Recent advances in the formalism allow us to simplify existing complex form solutions to real form ones and to solve heretofore unsolved problems. As a result many interesting and physically unexpected phenomena have been discovered. For instance, for the anisotropic bimaterial with the interface containing the x3-axis subject to a line f...
NOTES ON RECENT DEVELOPMENT OF ROCK MECHANICS

Abstract(3023) PDF(818)
Abstract:
The present paper summarizes the developments in the studies of constitutive relations of rocks during the past decade. The main topics include-theories of strength and damage, plasticity and mechanics of distributed cracks in rocks.
RECENT ADVANCES IN INDENTATION STUDIES IN SOLID MECHANICS
1992, 22(2): 183-193. doi: 10.6052/1000-0992-1992-2-J1992-019
Abstract(1651) PDF(589)
Abstract:
This paper summarizes the development of the research on indentation problems during the last ten years or so. It emphasises the new achievements in theoretical and experimental researches on indentation fracture of brittle materials, and discusses the relations between dynamic and static indentation fracture. Finally a new method of determining fracture toughness relevant to indentation is described
THE EFFECT OF SOLITONS ON THE ACCELERATIONOF PARTICLES
1992, 22(2): 194-207. doi: 10.6052/1000-0992-1992-2-J1992-020
Abstract(1635) PDF(650)
Abstract:
Both the heating of plasma and the acceleration of particles are important topics in plasma physics and plasma astrophysics. For solving these problems in the strong turbulent regime it is necessary to study the interaction of solitons with particles. This paper reviews several methods that have been used to solve these problems successfully, and the progress made at present, and discusses some still unsolved problems. As the results of interaction of solitons with plasma particles, a highly populated supra...

Abstract:
The newly developed finite element method of lines is briefly described and the recent advances are reviewed and its future development is discussed.
ADVANCES IN THE RESEARCH FOR GAS-CONDENSATE FLUID FLOWS THROUGH POROUS MEDIA
1992, 22(2): 213-227. doi: 10.6052/1000-0992-1992-2-J1992-022
Abstract(1745) PDF(777)
Abstract:
This paper outlines the status of researches for gas-condensate fluid flows through porous media. Characteristics, well-testing and developing schemes of gas-condensate reservoirs are briefly described. Their corresponding governing equations, analytical solutions and numerical simulations are also discussed. Finally, some key research topics of gas-condensate fluid flow through porousmedia are proposed
