Singular Plastic Fields in Steady Penetration of a Rigid Cone
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The essential features of the active plastic zone at the tip of a penetrating rigid cone are investigated for a rigid/perfectly plastic solid. An exact solution is suggested for the plastic ...
Frictional Collapse of Granular Assemblies
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The frictional collapse of an assembly of equisized spheres is studied by a discrete element model. The macroscopic constitutive response is determined as a function of the level of Coulomb ...
The Imperfection Sensitivity of Isotropic Two-Dimensional Elastic Lattices
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The imperfection sensitivity of the effective elastic properties is numerically explored for three planar isotropic lattices: fully triangulated, the Kagome grid, and the hexagonal honeycomb. Each ...
Elastic Boundary Layers in Two-Dimensional Isotropic Lattices
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The phenomenon of elastic boundary layers under quasistatic loading is investigated using the Floquet–Bloch formalism for two-dimensional, isotropic, periodic lattices. The elastic boundary layer ...
Experimental Investigation Into the Deep Penetration of Soft Solids by Sharp and Blunt Punches, With Application to the Piercing of Skin
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: An experimental study has been conducted on the penetration of silicone rubbers and human skin in vivo by sharp-tipped and flat-bottomed cylindrical punches. A penetrometer was developed to ...
Flow of Damp Powder in a Rotating Impervious Cone
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A one dimensional analytical model is developed for the steady state, axisymmetric flow of damp powder within a rotating impervious cone. The powder spins with the cone but migrates up the ...
