A REVIEW ON THE NEW THEORY OF OPTIMAL CONTROL AND COMPUTATIONAL STRUCTURAL MECHANICS

1993, 23(1): 1-11. doi:10.6052/1000-0992-1993-1-J1993-001

Abstract:
Optimal control and computational mechanics arc originally two different fields, each of which has its own theoretical system. It has been found that there exists an analogy between the two fields in the form of mathematical formulation. This discovery helps developments in the two fields. Special advantages are revealed in using computational structural mechanics to solve optimal control problems, which gives birth to a new theory. The paper presents a brief review on the new theory in solving LQ control p...

POLARIZING OPTIC PROBLEMS IN THE TRANSPARENT PHOTOELASTIC STUDY OF FIBER REINFORCED COMPOSITES

1993, 23(1): 12-22. doi:10.6052/1000-0992-1993-1-J1993-003

Abstract:
This paper summarizes the reccut investigations on the optical trans-porting phenomenon through anisotropic and hetergencous Fiber reinforced com-positcs. With the use of a Laser-microscope Analyser, recent: study revealed that the polarizing optic behavior of optically heterogeneous fiber reinforced composites is quite different from that of homogeneous birefringent materials which are well defined and described by the conventional theory of Jone's matrix theory of photoelasticity. In the attempt to interp...

RECENT DEVELOPMENTS AND EMPHASES IN THE DYNAMIC PLASTIC RESPONSE OF STRUCTURES

1993, 23(1): 23-33. doi:10.6052/1000-0992-1993-1-J1993-004

Abstract(1538)

PDF(851)

Abstract:
Beginning with the: background of engineering applications and the research characteristics of the dynamic plastic response of structures, this article outlines recent developments in the topic. Several fundamental theoretical problems and research methods of current interest on dynamic plastic response are reviewed, and the problems which remain to be solved in numerical and approximate analysis are also suggested.
