The state of the art in nonlinear constitutive modeling of high temperature materials was reviewed and the need for future research and development efforts in this area was identified. Considerable research efforts are urgently needed in the development of nonlinear constitutive relations for high temperature applications prompted by recent advances in high temperature materials technology and new demands on material and component performance. Topics discussed include: constitutive modeling, numerical methods, material testing, and structural applications.Document ID19850023217Acquisition SourceLegacy CDMSDocument TypeConference ProceedingsDate AcquiredSeptember 5, 2013Publication DateJune 1, 1985Subject CategoryStructural MechanicsReport/Patent NumberNAS 1.55:2369E-2368NASA-CP-2369Accession Number85N31530Distribution LimitsPublicCopyrightWork of the US Gov.
