Abstract:

The present work employs some of the major elements of these new computers which are promising parallel computer architectures of the future, and describes some recent developments in the finite element analysis of process modeling and manufacturing applications of composites that are designed to exploit these major elements for large scale engineering applications. The work includes finite element computational schemes, data structures and interprocessor communication strategies for the implementation of large scale practical advanced manufacturing simulations with particular emphasis on isothermal resin transfer molding RTM process manufacturing simulations on the symmetric multiprocessor. For process modeling studies thin shell composite mold configurations are used to illustrate the validity of the present implementation of 1 the traditional explicit control volume-finite element, and 2 a recently developed and new pure finite element implicit methodology in conjunction with a diagonal preconditioned conjugate gradient solver for parallel computations on the SGI Power Challenge and the SGI Origin2000 symmetric multiprocessor machines. The techniques developed are applied to large scale problems to demonstrate the practical applicability to realistic industrial size problems.
