Nondestructive 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 کاملA Review of Microwave Thermography Nondestructive Testing and Evaluation
Microwave thermography (MWT) has many advantages including strong penetrability, selective heating, volumetric heating, significant energy savings, uniform heating, and good thermal efficiency. MWT has received growing interest due to its potential to overcome some of the limitations of microwave nondestructive testing (NDT) and thermal NDT. Moreover, during the last few decades MWT has attract...
متن کاملNondestructive Testing of Wood Defects based on Stress Wave Technology
The wood samples were tested by the technique of stress wave, and the testing results were analyzed by using the statistic software of SPSS. The results showed that the length, density and knots of wood, the sizes of holes and numbers of holes have significant influence on propagation parameters and dynamic modulus of elasticity. Under the same specifications, the propagation time of the stress...

It stressfully introduces foreign contributions in the field in order to provide some useful references to the researchers.
متن کاملNondestructive Evaluation: Wood
Preservationists look to methods of nondestructive evaluation (NDE) to answer questions about the condition, strength, and construction details of wood in historic buildings in the interest of saving historic fabric and reducing or eliminating damage to significant historic features or materials caused by investigative probes. Many times, a basic wood inspection can answer questions posed when ...
