Whereas mechanics theories for isotropic materials have been almost matured, those for
anisotropic or composite materials well established are only limited to linear elasticity. All of …

Elasto-plastic models for composites can be classified into three categories in terms of a
length scale, ie, macro scale, meso scale, and micro scale (micromechanics) models. In …

Nickel-based single-crystal alloys undergo microstructural degradation induced by thermal
exposure. The directional rafting of microstructures significantly affects the mechanical …

This paper has three major objectives related to the development of computational
micromechanics models of Ni-based superalloys, containing a large number of annealing …

This paper develops non-Schmid crystal plasticity constitutive models at two length scales,
and bridges them in a multi-scale framework. The constitutive models address thermo …

Mechanical behavior and reliability of composites are driven significantly by microstructural
variability. Such variability can be present in the form of both morphological and constituent …

In this study, variability in transverse mechanical properties of unidirectional (UD)
composites arising from the randomness present in the geometrical descriptors of the fibers …

Consideration of a core and mantle configuration for individual grains is a prominent method
to capture the grain size-dependence in the constitutive models for polycrystal material. The …

The never-ending struggle to design new materials for supporting innovative engineering
requirements gives composites a worthy focus. This endeavor is challenged by the …

A multi-scale analysis for turbine guide vanes made of 2D braided SiC f/SiC composites in
high-cycle fatigue (HCF) regime is developed in this work. This analysis combines the …
