Book Description
The third and fourth years of a 4-year research program, part of the NASA HOST Program, are described. The program goals were: (1) to develop and validate unified constitutive models for isotropic materials, and (2) to demonstrate their usefulness for structural analysis of hot section components of gas turbine engines. The unified models selected for development and evaluation were those of Bodner-Partom and of Walker. The unified approach for elastic-viscoplastic constitutive equations is a viable method for representing and predicting material response characteristics in the range where strain rate and temperature dependent inelastic deformations are experienced. This conclusion is reached by extensive comparison of model calculations against the experimental results of a test program of two high temperature Ni-base alloys, B1900+Hf and Mar-M247, over a wide temperature range for a variety of deformation and thermal histories including uniaxial, multiaxial, and thermomechanical loading paths. The applicability of the Bodner-Partom and the Walker models for structural applications has been demonstrated by implementing these models into the MARC finite element code and by performing a number of analyses including thermomechanical histories on components of hot sections of gas turbine engines and benchmark notch tensile specimens. The results of the 4-year program have been published in four annual reports. The results of the base program are summarized in this report. The tasks covered include: (1) development of material test procedures, (2) thermal history effects, and (3) verification of the constitutive model for an alternative material. Chan, K. S. and Lindholm, U. S. and Bodner, S. R. Unspecified Center CONSTITUTIVE EQUATIONS; GAS TURBINE ENGINES; HOT SURFACES; ISOTROPIC MEDIA; MODELS; STRUCTURAL ANALYSIS; TECHNOLOGY ASSESSMENT; DEFORMATION; ELASTIC PROPERTIES; HIGH TEMPERATURE; LOADS (FORCES); NICKEL ALLOYS; STRAIN RATE; TEMPERATURE DEPENDENCE; THERMAL ANALY...
