The Meshless Local Petrov-Galerkin (MLPG) Method

By S. N.Atluri, S. Shen

This book is the first monograph (in the new series, CREST), on this new class of meshless methods, that are expected to revolutionalize engineering/science analyses. It not only deals with several meshless methods in general, but also with the Meshhless Local Petrov-Galerkin (MLPG) method, pioneered by the authors, in particular.
