Stress Induced Structural Transformations in Au Nanocrystals
Abhinav Parakh, Sangryun Lee, Mehrdad T. Kiani +5
Nanocrystals can exist in multiply twinned structures like the icosahedron, or single crystalline structures like the cuboctahedron or Wulff-polyhedron. Structural transformation b…
Nucleation of Dislocations in 3.9 nm Nanocrystals at High Pressure
Abhinav Parakh, Sangryun Lee, K. Anika Harkins +7
As circuitry approaches single nanometer length scales, it is important to predict the stability of metals at these scales. The behavior of metals at larger scales can be predicted…
Investigation of effective thermoelectric properties of composite with interfacial resistance using micromechanics-based homogenisation
Jiyoung Jung, Sangryun Lee, Byungki Ryu +1
We obtained the analytical expression for the effective thermoelectric properties and dimensionless figure of merit of a composite with interfacial electrical and thermal resistanc…
Applicability of the interface spring model for micromechanical analyses with interfacial imperfections to predict the modified exterior Eshelby tensor and effective modulus
Sangryun Lee, Youngsoo Kim, Jinyeop Lee +1
Closed-form solutions for the modified exterior Eshelby tensor, strain concentration tensor, and effective moduli of particle-reinforced composites are presented when the interfaci…
Modified Eshelby tensor for an anisotropic matrix with interfacial damage
Sangryun Lee, Jinyeop Lee, Seunghwa Ryu
We derive a simple tensor algebraic expression of the modified Eshelby tensor for a spherical inclusion embedded in an arbitrarily anisotropic matrix in terms of three tensor quant…
