In this study, the relation between leaf area and its dimensions was estimated using a non-destructive method. This method is based on this fact that the leaf shape does not change during the growing season. In this method, leaf area during the growing season is estimated based on the dimensions of the smallest leaf in the initial stage of plant growth or at any growth stage by measuring the le...

This work presents modern approach for damage detection in the composite main rotor blades MRB of helicopters. All inspections were made with the use automated systems based on Personal Computer – acquisition and database collection. Non Destructive Testing Methods used for the purpose of that work were the following: • qualitative: shearography, DAIS; • quantitative: Mechanical Impedance Analy...

High-density polyethylene (HDPE) is widely used for above-ground storage tanks (ASTs). However, there are currently no guidelines the non-destructive testing (NDT) and evaluation (NDE) of HDPE ASTs. Moreover, feasibility, limitations, challenges using NDT techniques field inspection ASTs have not been well established. This study both infrared thermography (IRT) ultrasonic (UT) Highlighting imp...

Maintenance manuals include general methods and procedures for industrial maintenance and they contain information about principles of maintenance methods. Particularly, Non-Destructive Testing (NDT) methods are important for the detection of aeronautical defects and they can be used for various kinds of material and in different environments. Conventional non-destructive evaluation inspections...
