It is shown that the consideration of microstructural parameters – volume fraction, surface density and particle shape – provides good estimates of the properties of cast iron with simply connected nodular graphite particles, but is insufficient for interconnected structures with vermicular and flake graphite.
The threshold stress, σo, included in the creep equation to explain the high-temperature behavior of discontinuously reinforced metal matrix composites (MMCs) is criticized on the basis of microstructural considerations and a new creep data analysis.
This paper analyzes the strength development in cement-stabilized silty clay based on microstructural considerations.
A new micromechanical stress strain model is developed for clay using the approach developed in earlier studies by Chang and Hicher [Chang, C.S., Hicher, P.Y., 2005. An elastic plastic model for granular materials with microstructural consideration. International Journal of Solids and Structures 42(14258 4277]277].
Microstructural consideration is implemented in the calculation using commercial finite element analysis to study the effect of thermal treatment for engineering applications.
However, when the design is more constrained and considerations of strain and microstructural heterogeneities and gradients are made part of the design criteria, we show that one die design promotes such gradients while the other minimizes them.
Engineering concepts of stress, strain, shear, yielding and failure are introduced and through consideration of microstructural mechanisms, the behaviour of materials under loading is discussed.
It is demonstrated that, with consideration of microstructural effects, the deformation and stress distributions in the cylinder are highly inhomogeneous during both the initial loading and the subsequent elastic and plastic expansion stages.
The microstructural lattice approach, which includes consideration of a continuum limit, allows us to select a type of fractional derivatives that will adequately and correctly describe fractional nonlocal continua.
The results substantiated that the consideration of realistic simulation scenarios in terms of microstructural inhomogeneity and annealing twin formation is essential for an accurate prediction of the recrystallization behavior of the investigated high-manganese steel.
