Abstract

Crack growth analysis using BEASY S.M. Niku, R.A. Adey Computational Mechanics BEASY, W ess ex Institute of Technology, Ashurst Lodge, Ashurst, Southampton, 2,4,4, ABSTRACT Catastrophic failure of engineering structures is caused by cracks that extend beyond a safe size. Cracks are present to some extent in all structures and can lead to failure or decrease in structural strength if they grow. This paper described an automatic procedure for predicting the growth of cracks in two dimensional structures and the key fracture data. The stress intensity factors. The procedure is implemented in a general purpose engineering analysis system BEASY. 1. INTRODUCTION The cost to industry of fracture was recently estimated in a report of the US Department of Commerce entitled "The economic effect of fracture in the United States". In this report it estimated that the cost of fracture was $119 billion dollars per year (4% of gross national product). It further estim
