Size-dependent Elasticity in Materials

arXiv (Cornell University) (2012)

Chi Huan Nguyen Shailendra P. Joshi

In this work, we combine the nonlocal theory of Eringen into the E-B beam bending together with nonlinear kinematics [3]. We briefly present the derivation and key equations of this nonlinearnonlocal beam theory and investigate the role of nonlinearity and nonlocality for simply supported nanoscaled beams.

Damage Progression in the Vicinity of a Hole

Journal of Thermoplastic Composite Materials (1994)

Shailendra P. Joshi Yuanchen Huang

Numerical simulations of damage progression in laminated composites with a hole are presented. The finite element procedure which incorporates two-phase continuum damage constitutive relations is utilized for the numerical predictions. The pre dictions from the numerical simulations are compared with the experimental results. The similarities and contradictions between predictions and experimental observations are dis cussed. Overall, the predictions are qualitatively close to experimental observations. The qualitative difference between predictions and experimental observations is obvious in laminates where delamination and edge stresses play a significant role in damage evolution up to ultimate failure. The discrepancy in results in these cases is due to limitation of the failure modes incorporated in the model and the damage induced by the out-of-plane stresses.

A Crystal Plasticity Investigation of Grain Size-Texture Interaction in Magnesium Alloys

SSRN Electronic Journal (2020)

Babak Ravaji Shailendra P. Joshi

This work investigates the microstructure-property linkages in magnesium (Mg) with an emphasis on understanding interaction effects between the grain size, texture, and loading orientation. A single crystal plasticity framework endowed with experimentally informed micro Hall-Petch type relations for the activation thresholds for slip and twinning is adopted to resolve polycrystalline microstructures over a broad texture-grain size space. The macroscopic trends from the simulations corroborate with experiments. The synergistic effects of microstructural engineering on the micromechanical characteristics are mapped, which reveal their role in the emergent macroscopic behaviors. The simulations indicate that for tempered twinning with grain refinement it is not necessary for the crystallographic size effect on twinning to be stronger than slip. While grain refinement and textural weakening reduce the net plastic anisotropy and tension-compression asymmetry they are sensitive to loading orientation. The results provide insight into the roles that engineered Mg microstructures may play in their damage behavior.
