Study of triaxial loading of segregated granular assemblies through experiments and DEM simulations
Venkata Rama Manoj Pola, Ratna Kumar Annabattula
A simple position-dependent body force-based confinement for simulating triaxial tests using the Discrete Element Method is presented. The said method is used to perform triaxial s…
Photo-activated dynamic isomerization induced large density changes in liquid crystal polymers: A molecular dynamics study
Akhil Reddy Peeketi, Edwin Joseph, Narasimhan Swaminathan +1
We use molecular dynamics simulations to unravel the physics underpinning the light-induced density changes caused by the dynamic trans-cis-trans isomerization cycles of azo-mesoge…
Voxelization based packing analysis for discrete element simulations of non-spherical particles
Venkata Rama Manoj Pola, Raghuram Karthik Desu, Ratna Kumar Annabattula
A voxelization based post-processing algorithm is proposed to analyze the packing of non-spherical particle assemblies simulated using the Discrete Element Method. Voxelization of…
Modified Stoney's equation with anisotropic substrates undergoing large deformations
Sai Sharan Injeti, Nihit Vyas, Ratna Kumar Annabattula
Residual stresses in a thin film deposited on a substrate results in a curvature of the system, which can be measured using the well known Stoney equation. Isotropic elasticity of…
A Thermal Discrete Element Analysis of EU Solid Breeder Blanket subjected to Neutron Irradiation
Yixiang Gan, Francisco Hernandez, Dorian Hanaor +3
Due to neutron irradiation, solid breeder blankets are subjected to complex thermo-mechanical conditions. Within one breeder unit, the ceramic breeder bed is composed of spherical-…
