This paper applies the genetic algorithm to back-analysis of displacements of roadway, combines the genetic algorithm and FLAC numerical software, studies and develops the elastoplastic displacement back-analysis program of roadway.
With the combination of genetic algorithm and FLAC numerical software, it also develops the back-analysis of displacement program on the basis of genetic algorithm method, and tests this method with specific elastic-plastic displacement example.
④This paper has the numerical analysis on the no widening areas of Daping tunnel using 2 D-σnumerical software, and analyses correct of the numerical analysis through comparing with monitoring data, further explores the numerical analysis on three broad bands of Daping tunnel.
This paper adopted MUTODYN-2D program, with the code the 2-D numerical simulations on penetrations of an oval-headed projectile into concrete targets are completed, and the concerned results are compared with the results of experiment.
To provide a theory for the optimized design of a U-tube ground heat exchanger used in ground source heat pumps, CFD software was used to simulate the processes of flow and heat transfer in the U-tube ground heat exchanger.
The RFPA(Rock Failure Process Analysis) code was used to make the numerical simulation of indirect tensile tests of three points bend,cirque crack and cirque hydraulic pressure crack. Suggestion was made on the application conditions of the tensile strength formula for each test method based on the obtained test results under different test conditions.
These meshes or grids can be easily incorporated into existing numerical software packages for further mechanical analysis and failure prediction of the geomaterials under external loading.
The model equations are employed in numerical software and used for the simulation of characteristic filling cases and the comparison with the conventional filling.
In this paper we present a set of linear algebra subroutines which serve as building blocks for numerical software, and develop algorithms to implement these subroutines as a portable library for parallel computers.
Self-Adapting Numerical Software (SANS) systems aim to automate some of the laborious human decision making involved in adapting numerical algorithms to problem data, network conditions, and computational platform.
This article deals with the processing of the mathematical model of a precision cam for the altitude transducer by N/C linear cutting technique, and the computer algorithm and the arrangement of numerical software.According to the algorithm stated in the article we can precisely calculate the moving locus of the molybdenum filament on the N/C linear cutting machine, eliminating the errors in principle and raising the precision in processing and productive efficiency.The said techniques have been applied to ...
This paper considers and designs the testing methods of comprehensive exa-mination and evaluation, testing software for the correctness, accuracy, amount of compu-tation work, applicability and intensity, etc., in the numerical software of the nonstiff andstiff ordinary differential equations.
in this paper, a parallel algorithm for the optimal control with, the linear quadric form is constructed and a FORTRAN code for the algorithm is designed,which could be run on "WUDP91" distributed parallel processing system, Wuhan University. The code can be used for equilibrium problem of a given dynamic system. For the economic system,its state and response can be adjusted and improved by policy control variables. For autonomous systems,the potimal control can be found to make the objective function achie...
