    Abstract: This case study paper presents the origins, philosophy, organization, development, and contributions of the joint Penn State-Georgia Tech Center for Computational Materials Design (CCMD), a NSF Industry/University Cooperative Research Center (I/UCRC) founded in 2005. As a predecessor of and catalyst for Integrated Computational Materials Engineering (ICME), the CCMD served as a basis for coupling industry, academia, and government in advancing the state of computational materials science and mechanics across a portfolio of process-structure-property-performance relations, with emphasis on education and training of the future workforce in computational materials design.

    A mesoscale approach for growth of 3D microstructurally small fatigue cracks in polycrystals

    Abstract: In the high cycle fatigue regime, microstructure attributes such as grain size, shape, and crystallographic orientation usually affect fatigue crack formation and early growth. However, most computational strategies and theoretical models for assessing the influence of the microstructure on early stages of fatigue crack formation and growth rely on simple constitutive models and 2D microstructures, which limit their applicability in design of microstructure of engineering materials. This work employs finite element simulations that explicitly render the 3D microstructure of an Face-centered cubic (FCC) alloy to evaluate the change of the driving force for fatigue crack formation and early stages of transgranular growth, including consideration of growth within individual grains and stress redistribution as the crack extends. The methodology is implemented using a crystal plasticity algorithm in ABAQUS and used to study the effect of microstructure on early fatigue life of a powder processed Ni-base RR1000 superalloy at 650℃ subjected to constant amplitude loading. The effects of the microstructure in extending a fatigue crack over the first few grains are analyzed.
