A non-destructive method for mapping formation damage

Ultrasonics, 2001
Abstract Applicability of an ultrasonic method for non-destructive mapping of formation damage is reported for the first time. Oil-saturated and `mud'-damaged Berea rock samples were prepared in the laboratory using a leak-off apparatus and machined dry rocks. The depth of `mud invasion' was monitored under varying conditions of overbalanced pressure

The membrane resonance method of non-destructive testing

Journal of Sound and Vibration, 1989
Abstract The physical basis of the membrane resonance method of non-destructive testing has been investigated both theoretically and experimentally. The method involves exciting the structure and monitoring the response at the same point, and can be used to detect the presence of delaminations or disbonds at that location.

A non‐destructive method of determining rock strength

Earth Surface Processes and Landforms, 1988
AbstractRock material strength is an important component of many geomorphological studies. Current methods for determining this parameter result in sample destruction, preventing further analysis. A new non‐destructive technique is described for indirectly determining material strength, by measuring Dynamic Young's Modulus. Tests have been conducted on

Excitation Method for Thermosonic Non-destructive Testing

2008
Thermosonics is a non-destructive testing method in which cracks in an object are made visible through the local generation of heat caused by friction and/or stress concentration. The heat is generated through the dissipation of mechanical energy at the crack interfaces by vibration.
