摘要：

A detailed study of the propagation of bidimensional (2D) through-thickness cracks has been conducted on a 304L austenitic stainless steel used in nuclear industry in view of providing a detailed description of the effective driving force to be introduced in numerical simulation of thermal fatigue crack arrays in some critical components. To answer this problem, crack closure is precisely determined for long cracks and 2D short cracks artificially obtained in CT specimens, for different loading conditions. The present results will be used to validate numerical simulations of crack closure presented in a second part as a sister paper. (C) 2013 Elsevier Ltd. All rights reserved.
