Abstract: A sandwich technique which utilizes an embedded polariscope consisting of two sheets of polarizing material cemented within a plastic model was evaluated for application to three-dimensional ...

Abstract: After a rather complete exploratory program described in previous papers, the photothermoelastic method was applied to the experimental evaluation of thermal-stress theories. The new technique was ...

Abstract: A governing design synthesis relationship is derived for the primary structural weight of membrane-type pressure vessels. The structural efficiency is associated with the configuration and the ...
