RETRACTED: Study of the New Leon model for concrete failure

This article has been retracted: please see Elsevier Policy on Article Withdrawal (http://www.elsevier.com/locate/withdrawalpolicy).This article has been retracted at the request of the Editor-in-Chief.The first 2 authors (Xu Juncai and Shen Zhenzhong) have submitted the article without informing the third author (Bernhard Valentini) and added his name as co-author without his permission.The article contains several pages that have been copied from the PhD thesis entitled 'A three-dimensional constitutive model for concrete and its application to large scale finite element analysis' by Bernhard Valentini (University of Innsbruck, 2011), without making any reference to it.One of the conditions of submission of a paper for publication is that the authors declare explicitly that their work is original and has not appeared in a publication elsewhere. Re-use of any data should be appropriately cited. As such this article represents a severe abuse of the scientific publishing system. The scientific community takes a very strong view on this matter and apologies are offered to readers of the journal that this was not detected during the submission process.
