Abstract:
1. A method of mitigating residual tensile stresses in a confined assembly comprising the steps of: a) securing a first surface of a first member to a substrate; b) cooling a portion of the first member to form a cooled portion with a cooling fluid sufficient to contract said portion of the first member forming a contracted portion to at least partially mitigate residual tensile stresses upon expansion of the first member after affixing a second surface of the first member to a second structural member, wherein said portion of the first member is located between the first surface of the first member and the second surface of the first member, and wherein the contracted portion of the first metal member creates a camber before the first metal member is affixed to the second structural member; and c) affixing the second surface of the first member containing the cooled portion to the second structural member.
