RISSome Remarks on the Equilibrium of Granular Materials Described by Constitutive Relations That Depend on the Gradients of the Density or Volume Fraction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: One of the ways of determining the properties of granular materials is to subject the material to a tri-axial state of stress with three distinct eigenvalues, in a cubical tri-axial testing equipment, the material tested ...
Prediction of the Onset of Failure in Elastomeric Solids With Weld Lines Being Represented as Localized Regions of Lower Density
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: We study the initiation of damage in a polymeric body in which there is a line defect due to the formation of a “weld line” that occurs when two polymer streams join together and then solidify. We show that damage initiates ...
Fidelity of the Estimation of the Deformation Gradient From Data Deduced From the Motion of Markers Placed on a Body That is Subject to an Inhomogeneous Deformation Field
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Practically all experimental measurements related to the response of nonlinear bodies that are made within a purely mechanical context are concerned with inhomogeneous deformations, though, in many experiments, much effort ...
