    Abstract

    In order to assess the extent of the damage produced in thin metallic sheets by high-energy laser radiation, the residual tensile strength of small-scale 7075-T6 alumimum alloy specimens has been measured after laser irradiation and cooling. The effect of applied loads during irradiation upon residual strength is found to be small for all loading levels except those approaching the elastic limit. In addition, the use of an equivalent hole size parameter to describe the extent of laser damage and to compare the strength-reducing effects of various irradiation parameters is proposed.
