Abstract
This paper describes the implementation and modification of a previously proposed unified viscoplastic constitutive model to simulate the behavior of a Yttria Stabilized Zirconia plasma sprayed thermal barrier coating. The model was recast for use in finite strain situations and modified to have a more physically acceptable non-associated flow rule. Temperature dependent material constants were found for a specific material using a novel approach based on Genetic Algorithms.
