Abstract
Official abstract text for this publication.
A tool having at least one vibration sensor and at least one standoff is disposed in a contact with a material and the at least one standoff of the tool is pushed into the material. Vibration is excited by the at least one vibration source and at least one coupling frequency of the tool is measured by the at least one vibration sensor. Based on the determined coupling frequency determining a contact stiffness of the at least one standoff and the mechanical properties of the material are determined taking into account mechanical properties of the at least one standoff.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method for determining mechanical properties of a material comprising: disposing a tool having at least one vibration sensor and at least one standoff in a contact with a material, pushing the at least one standoff of the tool into the material, exciting vibration by the at least one vibration source, measuring at least one coupling frequency of the tool by the at least one vibration sensor, determining a contact stiffness of the at least one standoff based on the determined coupling frequency and determining the mechanical properties of the material based on the determined contact stiffness of the at least one standoff and on mechanical properties of the at least one standoff. 2. The method of claim 1 wherein the at least one vibration source is disposed inside the tool. 3. The method of claim 1 wherein the at least one vibration source is disposed outside the tool. 4. The method of claim 1 wherein the mechanical properties of the material and of the at least one standoff are Poisson ratio and Young modulus of the material and of the at least one standoff. 5. The method of claim 1 wherein material is a formation surrounding a borehole. 6. The method of claim 1 wherein the tool is clamped to the material.
