Revisiting Stress Analysis in a Three-Dimensional Elastic Hollow Sphere under Uniaxial Compression via the Inverse Laplace Transform Expressions within an Elastodynamic Framework
Satoshi Takada, Shintaro Hokada
The stress analysis of a three-dimensional elastic hollow sphere subjected to uniaxial compression is revisited, employing an elastodynamic framework. Through the application of th…
Inverse Reconstruction of Moving Contact Loads on an Elastic Half-Space Using Prescribed Surface Displacement
Satoshi Takada, Yosuke Mori, Shintaro Hokada
This study investigates the elastic response of a two-dimensional semi-infinite medium subjected to a moving surface load with a prescribed displacement profile. As a fundamental s…
Discontinuous change of viscosity in a sheared granular gas with velocity-dependent restitution
Makoto R. Kikuchi, Yuria Kobayashi, Satoshi Takada
We investigate the rheology of a sheared granular gas composed of hard spheres with a velocity-dependent restitution coefficient. Using kinetic theory, we derive the shear viscosit…
Kinetic theory of dilute weakly charged granular gases with hard-core and inverse power-law interactions under uniform shear flow
Yuria Kobayashi, Makoto R. Kikuchi, Shunsuke Iizuka +1
We develop a kinetic-theory framework to investigate the steady rheology of a dilute gas interacting via a repulsive potential under uniform shear flow. Starting from the Boltzmann…
Proposal for fast computational method for Hertzian contact theory
Shintaro Hokada, Shunsuke Iizuka, Satoshi Takada
Fast computational method for Hertzian contact theory is proposed. An incremental formula is introduced to calculate the ellipticity of the contact disk when two elastic bodies are…
Rheology of dilute granular gases with hard-core and inverse power-law potentials
Yuria Kobayashi, Shunsuke Iizuka, Satoshi Takada
The kinetic theory of dilute granular gases with hard-core and inverse power-law potentials is developed. The scattering process is studied theoretically, which yields the relative…
