SUMMARY In this paper, an equivalent domain integral (EDI) method and the attendant numerical algorithms arc presented for the computation of a near-crack-tip field parameter, the vector J ε-integral, and its variation along the front of an arbitrary three-dimensional crack in a structural component. Account is taken of possible non-elastic strains present(More)
The Java programming language has several features, which makes it attractive for software development in computational engineering and sciences. One major obstacle to use of Java in computationally intensive applications is its reputation of a slow language in comparison to Fortran or C. In this paper the performance of the developed Java finite element(More)
1 The performance of the developed Java finite element code is compared to that of the C finite element code on the solution of three-dimensional elasticity problems using Intel Pentium 4 computer. Untuned Java code is approximately two times slower then analogous C code. It is shown that code tuning with the use of blocking technique can provide Java/C(More)
An introduction to the domain decomposition method for parallel finite element analysis is presented. The domain decomposition method allows decomposition of large-size problem solutions to solutions of several smaller size problems. Algorithms of domain partitioning with compute load balancing as well as direct and iterative solution techniques are(More)
