Calibration, validation, and verification including uncertainty of a physically motivated internal state variable plasticity and damage model

Autor: Mark F. Horstemeyer, Kiran Solanki, W.G. Steele, Youssef Hammi, J.B. Jordon

Publikováno v: International Journal of Solids and Structures. 47:186-203

In this paper, we illustrate a formal calibration, validation, and verification process that includes uncertainty in an internal state variable plasticity-damage model that is implemented in a finite element code. The physically motivated continuum m

Mississippi DOE EPSCoR planning grant. Final report

Autor: W.G. Steele

The Mississippi DOE EPSCoR planning grant committee identified three focus areas for a proposal submitted on January 25, 1995, to the US DOE: Human Resource Development, Environmental Synergisms from Fuel Mixtures of Tire Particles and Low Rank Coals

Product design optimisation with microstructure-property modelling and associated uncertainties

Autor: Masoud Rais-Rohani, W.G. Steele, Mark F. Horstemeyer, Kiran Solanki, Erdem Acar

Publikováno v: International Journal of Design Engineering. 2:47

In this paper, we present a methodology for simulation-based product design optimisation using an internal state variable (ISV) constitutive modelling approach that captures the microstructure-property relations in the material. By modelling the stoc

Fission gas disposition in decay heat environment

Autor: W.G. Steele, A.R. Wazzan, David Okrent

Publikováno v: Nuclear Engineering and Design. 70:187-199

A computer code is developed to model fission gas disposition in UO2 fuel during nearly isothermal heating, as would result from decay heat. The intragranular analysis, random diffusion model, uses a spatial solution for random migration and bubble c

Steady-state fission gas behavior in uraniumplutoniumzirconium metal fuel elements

Autor: A.R. Wazzan, David Okrent, W.G. Steele

Publikováno v: Nuclear Engineering and Design. 113:289-295

An analysis of fission gas release and induced swelling in steady state irradiated U—Pu—Zr metal fuels is developed and computer coded. The code is used to simulate, with fair success, some gas release and induced swelling data obtained under the

Special topics reports for the reference tandem mirror fusion breeder. Volume 2. Reactor safety assessment

Autor: C.P.C. Wong, K.R. Schultz, J.K. Garner, I. Maya, S.J. Bradbury, D.H. Berwald, C.G. Hoot, W.G. Steele

The safety features of the reference fission suppressed fusion breeder reactor are presented. These include redundancy and overcapacity in primary coolant system components to minimize failure probability, an improved valve location logic to provide
