From page 52...
... He attempted to enlist in the Naval Construction Battalions (the Seabees) where he could use his engineering education, but was rejected because of his poor eyesight.
From page 53...
... Ray continued to Japan and was part of the occupying force on the island of Okinawa. Ironically, having been rejected earlier by the Seabees, when his Air Corps construction battalion arrived at Okinawa he was immediately reassigned to a Seabee unit working on the construction of an airfield runway and the aircraft control tower.
From page 54...
... The FEM was a direct competitor to the finite difference method, which was being used to solve many problems in continuum mechanics. When Ray returned from Norway in fall 1957 he put a note on the student bulletin board asking students to contact him if they were interested in conducting finite element research for the analysis of plate and shell structures.
From page 55...
... The paper reported on the finite element analysis of the 250-foot-high Norfork Dam in Arkansas, which had developed a vertical crack during construction in 1942. The finite element analysis correctly predicted the location and size of the crack, which apparently was due to temperature changes, and produced realistic estimates of displacements and stresses in the dam and foundation for both gravity and several hydrostatic load conditions.

... earthquake of 1964. He was a member of the UNESCO Seismology and Earthquake Engineering Mission to the Mediterranean Area in 1962, the US delegation to the UNESCO Governmental Meeting on Seismology and Earthquake Engineering in Paris in 1964, and the US delegation to inspect earthquake engineering research and construction in the USSR in 1969.

... . He was also active in professional societies, as chair of the American Society of Civil Engineers Engineering Mechanics Division executive committee, and as a member of the board of directors of the Structural Engineers Association of Northern California, Seismological Society of America, and Earthquake Engineering Research Institute.
From page 58...
... Nearly 80 years later, the Seattle mountaineering community refers to this trip as the Ptarmigan Traverse and it is still considered a challenging trip using modern equipment. Members of Ray's family and his close friends believe the impression made on Ray as a member of the Ptarmigan Club was profound.
