Transcription: Some structural analysis problems are so massive that they require a Cray research system. Such was the case at Pratt & Whitney Corporation when engineers were asked to redesign the space shuttle's liquid oxygen pump. The pump housing was individually modeled as 14 complex sub-assemblies, making this redesign one of the largest structural analysis problems ever attempted. One of the critical problems simulated was the uneven displacement of bearing surfaces when subjected to the thermal stress of liquid oxygen under varying high pressures. Nonlinear contact elements accurately transfer forces ...
