ccession number:20103213127440 Title:The G2 constant displacement discontinuity method - Part II: Solution of half-plane crack problems Authors:Exadaktylos, G. (1); Xiroudakis, G. (1) Author affiliation  1) Mining Engineering Design Laboratory, Department of Mineral Resources Engineering, Technical University of Crete, GR 73100, Chania, Greece Corresponding author:Exadaktylos, G.(exadakty@mred.tuc.gr) Source title:International Journal of Solids and Structures Abbreviated source title:Int. J. Solids Struct. Volume:47 Issue:18-19 Issue date:September 2010 Publication year:2010 Pages:2578-2590 Language:English ISSN:00207683 Document type:Journal article (JA) Publisher:Elsevier Ltd, Langford Lane, Kidlington, Oxford, OX5 1GB, United Kingdom Abstract:In the previous Part I, the G2 constant displacement discontinuity element was presented that is dedicated for the fast (only one collocation point per element), stable and accurate numerical solution of modes I, II and III cracks of arbitrary shape in an infinite plane isotropic elastic body. Herein, another G2 constant displacement discontinuity element is constructed for the case of cracks in the half-plane. It is successfully validated against existing semi-analytical and numerical solutions of crack problems in the half-plane. © 2010 Elsevier Ltd. All rights reserved.
