Abstract:

A state-of-art survey in the rapidly developing field of meso-mechanics, including its definition, main research issues and the domain of applications, is presented here. Emphasis is also placed on the new advances in meso-damage mechanics. The future research trends and opportunities of meso-mechanics are outlined in the final part of the paper.

The constitutive theories of elastic-visco-plasticity and their applications

Abstract:

A survey of the researches and developments on the mechanical behavior of materials with combined elastic, viscous and plastic characteristics is given in this paper. The methodologies, the representations, and the applications of elastic-visco-plastic constitutive theories are reviewed.

FLOW OF POLYMERIC LIQUIDS THROUGH POROUS MEDIA

1992, 22(1): 20-33. doi: 10.6052/1000-0992-1992-1-J1992-003

Abstract:
Considerable progress has been achieved an the research on the flow of polymeric liquids through porous media in recent years. In this paper, main advances in this area are reviewed and the emphasis is put on the theoretical approaches on the mechanism and some recent active research branches of the flow of polymer solutions through porous media. It is pointed out that among the macro-effects on the homogeneous fluids with non-slipping boundary conditions, non-Newtonian (shearthinning) behavior has been qua...

WAVE-VORTEX INT ERACT IONS (II)

1992, 22(1): 35-46. doi: 10.6052/1000-0992-1992-1-J1992-005

Abstract(1984)

Abstract:
Wave7vortex interaction is one of crucial fields of modern nonlinear unsteady fluid dynamics. This paper presents a systematic review on the progress of studies on the interactions between weak, longitudinal and transverse waves (e. g., acoustic and vortical waves) and laminal and axial vortices. The review covers the vortex sound theory, the two-dimensional theory on receptivity and unsteady Kutta condition for the vortex layer separation from sharp edge and smooth surface as well as the free vortex layer,...

COMPUTATIONAL METHODS FOR VORTEX FLOW FIELDS GENERATED BY AERODYNAMICAL BODIES AT HIGH ANGLES OF ATTACK

Abstract:
This paper reviews the progress in computational methods for vortex flow fields shedding from aerodynamical bodies at high angles of attack, and discusses in detail various potential flow models used to calculate the vortex flow fields.

SOME RECENT ADVANCES IN CAVITATION DAMAGE RESEARCH

1992, 22(1): 58-63. doi: 10.6052/1000-0992-1992-1-J1992-007

Abstract(2332)

PDF(661)

Abstract:
A review of reccnt advances in cavitation damage research is made in the present work. Cavitation damage occurred in a hydraulic machinery in varying degrees is a complex phenomenon. Therefore, studies on cavitation erosion were performed in many fields, such as in hydrodynamics, material science and physico-chemistry. The achievements in both basic and applied researches are summarized in this paper so as to promote further investigations.
