Dronacharya College of Engineering | Vol. 1 | Issue 1 | February 2011 ISSN No. 2231-3273 FROM THE DESK OF EXECUTIVE EDITOR Dear Readers, We, at Dronacharya College of Engineering, Greater Noida, are highly excited to release the first issue of bi-annual Research Journal “International Journal of Engineering Sciences and Management”. We hope that you will benefit while going through the research papers contributed for journal by the authors from India and abroad. We, at our College, use innovative instructional tools and strategies to catalyze excellence in teaching and research in engineering, science and humanities. Our aim is to transform raw students to graduates who are not only sought after by the reputed employers, they also contribute their role in the development of our society. Our College presents a commendable confluence of traditional and contemporary culture. My heartfelt thanks to “Advisory” and “Editorial” Boards comprising of eminent persons in their respective areas for their guidance and support. I also thank our Management and Principal of our College for their support in the launching of Journal. I want to mention that it would not have been possible to bring out excellence of the Journal without the contribution of eminent authors from India and abroad. We were highly pleased to receive a large number of quality research papers for the very first issue of our Journal. It was a difficult task for the Reviewers and the honorable members of the 'Editorial Board' to review the shortlist and accept papers for this issue. Our deepest gratitude goes to all those authors and further, we request and wish similar cooperation and contribution for the subsequent issues of Journal. Wishing you a very exciting and thought-stimulating reading.

Jiang, X. Gao, and T. S. Srivatsan e-mail: [email protected] Department of Mechanical Engineering, The University of Akron,Akron, Ohio 44325 ABSTRACT In this paper, we describe a cohesive zone model for the prediction of failure of engineering solids and/or structures. A damage evolution law is incorporated into a three-dimensional, exponential cohesive law to account for material degradation under the influence of cyclic loading. This cohesive zone model is implemented in the finite element softwareABAQUS through a user defined subroutine. The irreversibility of the cohesive zone model is first verified and subsequently applied for studying cyclic crack growth in specimens experiencing
