Journal ArticleDOI
Finite element modelling and simulation of indentation testing: a bibliography (1990‐2002)
TL;DR: In this article, a bibliographical review of the finite element modelling and simulation of indentation testing from the theoretical as well as practical points of view is given, with references to papers, conference proceedings and theses/dissertations that were published between 1990 and 2002.
Journal ArticleDOI
Quasi-static normal indentation of an elasto-plastic substrate by a periodic array of elastic strip punches
TL;DR: In this article, the plane-strain, elasto-plastic contact problem is treated for a substrate that is perfectly plastic post yield, and so simulates compression molding of some metals at elevated temperatures.
Dissertation
Sources of error in relating nanoindentation results to material properties
TL;DR: In this article, the effect of sample tilt on results of nanoindentation tests was investigated, and it was shown that for materials that sink-in and those that pile-up, the projected contact area of a tilted sample is higher than that estimated by the standard area function, which leads to overestimation of the hardness and elastic modulus.

Journal ArticleDOI
The correlation of indentation experiments
TL;DR: In this article, a simplified theoretical model of this behaviour is obtained by extending R. Hill's theory of expanding a cylindrical or spherical cavity in an elastic-plastic material to ensure compatibility between the volume of material displaced by the indenter and that accommodated by elastic expansion.

Elastic analysis of some punch problems for a layered medium
TL;DR: In this article, the problem of flat-ended cylindrical, quadrilateral, and triangular punches indenting a layered isotropic elastic half-space is considered, and solutions are obtained numerically.
Journal ArticleDOI
Analysis of Vickers indentation
TL;DR: In this article, the theoretical foundation for the commonly used Vickers test was explored and the influence of large elastoplastic deformations was also assessed, based on the finite element method.

Finite element simulation of indentation experiments
A.K. Bhattacharya,William D. Nix +1 more
TL;DR: In this article, the authors used the finite element method under the conditions of frictionless and completely adhesive contact and within the context of incremental elasto-plasticity to study the elastic and plastic properties of materials on a sub-micrometer scale.
Journal ArticleDOI
Void growth and failure in notched bars
TL;DR: In this paper, void growth and ductile failure in the non-uniform multiaxial stress fields of notched bars are studied numerically and experimentally, using an elastic-viscoplastic constitutive relation that accounts for strength degradation resulting from the growth of microvoids.
