Because the 2195 aluminum-lithium of the super lightweight external tank (SLWT ET) has a lower toughness than the 2219 aluminum used in previous ET's, careful attention must be paid to stress concentration in the SLWT ET. This report details the initial analysis performed by NASA to determine the material properties required to ensure structural integrity in these critical areas.
