Nondestructive Testing of Mechanical Parameters for Wood-based Materials
This article describes the national and international history, present situation and developing tendency in the research on nondestructive testing of mechanical parameters of Wood-based materials. It stressfully introduces foreign contributions in the field in order to provide some useful references to the researchers.
متن کاملNondestructive maturity determination of durian by force vibration
This paper proposes a method for determining maturity levels of durian by using nondestructive vibration. The vibration is transferred directly through durian at a region between prickles located at the middle of durian. The measurement of frequency response from vibration of durian is performed by using laser doppler. The signal is processed for finding velocity of vibration, elastic constants...
متن کاملNondestructive Maturity Determination of Durian by Force Vibration and Ultrasonic
The nondestructive determination of the maturity of durian is an important process for quality control. Since durian has specific properties, such as the thickness of peel, non-uniformity of shape, roughness of prickle skin, largeness of size etc., the nondestructive determination of the maturity is hard to perform. This paper proposes two approaches for determining maturity of durian by using ...
متن کاملNondestructive Testing of Wood
Nondestructive evaluation of materials, the science of identifying the physical and mechanical properties of materials without altering their end-use capabilities, is valuable in defining relationships between properties and performance of materials. Nondestructive evaluation techniques using these relationships have current industrial applications. They are used for machine stress rating of lu...
متن کاملNondestructive Testing Resolution:
The practical limits on resolution of images from seismic or radar (electromagnetic) data depend on the spectrum of the source pulse, the incompleteness of the recording geometry, and the fidelity with which one can model the reference medium. These factors together prevent one from recovering a point image from data produced by a point diffractor in a given body. A simple imaging formula quant...
