COLLOCATION AND FINITE ELEMENTS--A COMBINED METHOD

Discusses advantages/disadvantages of the finite element techniques and of the modified mapping-collocation (MMC) techniques for analytical solutions of fracture mechanics problems. Reports one of several AMMRC investigations toward development of a procedure aimed at combining the two techniques to take advantage of the best features of each. Presents examples and their solutions using first the MMC formulation and then the finite element formulation; lastly, the examples are addressed using a combined methods formulation. Results and observations relative to the three methods are discussed.
