RISNonlinear, Large Deformation Finite-Element Beam/Column Formulation for the Study of the Human Spine: Investigation of the Role of Muscle on Spine Stability
Publisher: American Society of Civil Engineers
Abstract: A nonlinear, large deformation beam/column formulation is used to model the behavior of the human spine under compressive load. The stabilizing roles of muscles are accounted for using Patwardhan’s assumption that muscles ...
A Direct Analysis of Three-Dimensional Elastic-Plastic Rolling Contact
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A novel treatment of a direct procedure for elastic-plastic analysis and shakedown is presented and its application to problems in three-dimensional rolling contact with or without case-hardened ...
Hyperelastic Anisotropic Microplane Constitutive Model for Annulus Fibrosus
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In a recent paper, (2006, “An Anisotropic Hyperelastic Constitutive Model With Fiber-Matrix Interaction for the Human Annulus Fibrosis,” ASME J. Appl. Mech., 73(5), pp. 815–824) developed an ...
