ABSTRACT The most important parameter in terms of material mechanical behavior knowledge is the modulus of elasticity, being traditionally obtained through destructive tests. The objective of this study is the verification of the potential use of the particle image velocimetry technique (PIV) as a tool to obtain the modulus of elasticity in sawed wood samples (Pinus oocarpa and Eucaliptus grandis) and wood panels (Plywood, LVL and OSB). The PIV technique has as characteristics the low cost of equipment, fast results, no need for contact with the object tested, accuracy and possibility of application in the field. The application of the PIV technique occurred during the static bending tests where the deformations were also measured with a dial indicator...

Manipulator requirements for NDT (ROV characteristics and the NDT tooling).
Provedor de dados: 5
Autores: Duncan, N.
Pressures of economics are driving the ROV industry to develop NDT equipment which will allow the ROV to detect, and assess, the presence of fatigue induced surface breaking defects in nodal welds and their associated heat affected zones. Two main techniques of NDT are currently being developed by Comex to provide ROV services to meet client needs. One is an MPI system and the other an Eddy Current system. Both are derivatives of equipment currently being used successfully by divers in the North Sea. The two systems are complementary to each other rather than in competition and offer a high degree of defect evaluation. This paper will discuss the requirements placed on the tool deployment system by the task, the worksite, the ROV characteristics and the...
