An efficient peridynamics-based statistical multiscale method for fracture in composite structure with randomly distributed particles
Zihao Yang, Shaoqi Zheng, Shangkun Shen +1
The fracture simulation of random particle reinforced composite structures remains a challenge. Current techniques either assumed a homogeneous model, ignoring the microstructure c…
An efficient multi-modes Monte Carlo homogenization method for random materials
Zihao Yang, Jizu Huang, Xiaobing Feng +1
In this paper, we propose and analyze a new stochastic homogenization method for diffusion equations with random and fast oscillatory coefficients. In the proposed method, the homo…
Heat capacity and thermal expansion of metal crystalline materials based on dynamic thermal vibration
Jieqiong Zhang, Junzhi Cui, Zihao Yang +2
A novel approach based on dynamic thermal vibration is proposed to calculate the heat capacity and thermal expansion coefficient (TEC) for metal crystalline materials from 0K to th…
Long lifetime of thermally-excited magnons in bulk yttrium iron garnet
John S. Jamison, Zihao Yang, Brandon L. Giles +5
Spin currents are generated within the bulk of magnetic materials due to heat flow, an effect called intrinsic spin-Seebeck. This bulk bosonic spin current consists of a diffusing…
Multiscale computational method for heat conduction problems of composite structures with diverse periodic configurations in different subdomains
Hao Dong, Junzhi Cui, Yufeng Nie +1
This study develops a novel multiscale computational method for heat conduction problems of composite structures with diverse periodic configurations in different subdomains. First…
Thermally Driven Long Range Magnon Spin Currents in Yttrium Iron Garnet due to Intrinsic Spin Seebeck Effect
Brandon L. Giles, Zihao Yang, John S. Jamison +5
The longitudinal spin Seebeck effect refers to the generation of a spin current when heat flows across a normal metal/magnetic insulator interface. Until recently, most explanation…
Scalable Nernst Thermoelectric Power using a Coiled Galfenol Wire
Zihao Yang, Emilio A. Codecido, Jason Marquez +3
The Nernst thermopower usually is considered far too weak in most metals for waste heat recovery. However, its transverse orientation gives it an advantage over the Seebeck effect…
The effect of the magnon dispersion on the longitudinal spin Seebeck effect in yttrium iron garnets (YIG)
Hyungyu Jin, Stephen R. Boona, Zihao Yang +2
We study the temperature dependence of the longitudinal spin-Seebeck effect (LSSE) in a yttrium iron garnet Y3Fe5O12 (YIG) / Pt system for samples of different thicknesses. In this…
Long range pure magnon spin diffusion observed in a non-local spin-Seebeck geometry
Brandon L. Giles, Zihao Yang, John Jamison +1
The spin diffusion length for thermally excited magnon spins is measured by utilizing a non-local spin-Seebeck effect measurement. In a bulk single crystal of yttrium iron garnet (…
Anisotropic defect-induced ferromagnetism and transport in Gd-doped GaN two-dimensional electron gasses
Zihao Yang, Thomas F. Kent, Jing Yang +3
Here we report on the effect of rare earth Gd-doping on the magnetic properties and magnetotransport of GaN two-dimensional electron gasses (2DEGs). Samples are grown by plasma-ass…
