DESTRUCTIVE & NON DESTRUCTIVE SURVEYS
In destructive testing, tests are carried out to the specimen’s failure, in order to understand a specimen’s performance or material behavior under different loads. These tests are generally much easier to carry out, yield more information, and are easier to interpret than non-destructive testing. Destructive testing is most suitable and economic for objects which will be mass produced, as the cost of destroying a small number of specimens is negligible. It is usually not economical to do destructive testing where only one or very few items are to be produced (for example, in the case of a building). Building structures or large non-building structures (such as dams and bridges) are rarely subjected to destructive testing due to the prohibitive cost of constructing a building, or a scale model of a building, just to destroy it. Earthquake engineering requires a good understanding of how structures will perform during earthquakes. Destructive tests are more frequently carried out for structures which are to be constructed in earthquake zones
Nondestructive testing (NDT) is the process of inspecting, testing, or evaluating materials, components or assemblies for discontinuities, or differences in characteristics without destroying the serviceability of the part or system. In other words, when the inspection or test is completed the part can still be used. Nondestructive testing (NDT) is a wide group of analysis techniques used in science and technology industry to evaluate the properties of a material, component or system without causing damage. Because NDT does not permanently alter the article being inspected, it is a highly valuable technique that can save both money and time in product evaluation, troubleshooting, and research. The six most frequently used NDT methods are eddy current, magnetic particle, liquid penetrant, radiographic, ultrasonic and visual testing
