摘要：

Depending on the expression used in Paris law relation, crack growth rate can be a function of loading conditions. However, for design purposes, it is costly and time consuming to obtain a complete map for fatigue crack growth behavior of adhesives. Accordingly, using a damage parameter where the Paris law constants are similar for different loading conditions is very helpful. In this paper, mode I crack growth (FCG) tests were performed at different loading conditions. Results show that performing one experiment would be enough to obtain Paris law constants if the effect of R ratio is considered in the relations.
