متن کاملPattern of Residual Stress in Rail by FEM Analysis and Strain Gage Sectioning Technique
Final step of rail manufacturing is cold rolling straightening process and it hassignificant effects on mechanical properties, straightness, flatness and development of residualstresses. Measurement of residual stresses after straightening process is obligated by railmanufacturing standards. In the present investigation, an attempt has been made to evaluateresidual stresses after straightening ...
متن کاملAnalytic Solution for the Indentation of a Transversely Isotropic Elastic Layer Bonded to a Rigid Foundation
The analytical solution for a transversely isotropic linear elastic layer bonded to a rigid foundation and indented by a rigid cylinder or sphere was developed. This solution follows procedures used by others to solve contact problems of linear anisotropic materials. The solution can be used to find the stress distribution and the displacement field in anisotropic layers like articular cartilag...
متن کاملIndentation of a rigid sphere into an elastic substrate with surface tension and adhesion.
The surface tension of compliant materials such as gels provides resistance to deformation in addition to and sometimes surpassing that owing to elasticity. This paper studies how surface tension changes the contact mechanics of a small hard sphere indenting a soft elastic substrate. Previous studies have examined the special case where the external load is zero, so contact is driven by adhesio...
متن کاملNonlinear analysis of oscillatory indentation in elastic and viscoelastic solids.
Determining the mechanical properties at micro- and nanometer length scales using nanoindentation or atomic force microscopy is important to many areas of science and engineering. Here we establish equations for obtaining storage and loss modulus from oscillatory indentations by performing a nonlinear analysis of conical and spherical indentation in elastic and viscoelastic solids. We show that...
