Indentation testing is a common method to assess the mechanical properties of materials
near their surface. The elasto-plastic properties may be determined from the force …

L'interprétation mécanique des essais d'indentation et de rayure est très complexe. La
compréhension est encore plus délicate lorsque les essais sont réalisés d'une part sur des …

The special feature of indentation test is the relative easiness of samples preparation of the
considered material. Its aim is to estimate mechanical properties from the measured FJh …

A parameter sensitivity analysis is carried out from numerical simulations of indention tests.
The indented material obeys a simple Drücker–Prager behavior with no hardening rule …

The unsaturated poromechanical behavior of Callovo-Oxfordian argillite (also referred to as
Meuse/Haute–Marne argillite) is analyzed by means of indentation tests at different …

The aim of this work is to identify parameters driving constitutive equations of materials with
displacement field measurements carried out by image stereo-correlation during an …

In this paper, we detail two approximate solutions to the problem of cone indentation of
elastoplastic solids. These solutions make it possible to determine the intrinsic stress-strain …

Ce travail de thèse, articulé en deux parties, se base sur l'étude des déformations
permanentes observées expérimentalement dans les verres soumis à de très hautes …

[en] This work aims at developing identification methods for clayey rock parameters. These
methods are necessary for the interpretation of the numerous data obtained at the ANDRA's …

La mecanique des roches se distingue des autre branches de l'ingenierie (automobile,
aeronautique...) par le simple fait que les materiaux etudies sont naturels. Les …
