Book Description
This report describes the development of a computer controlled direct-current potential-difference crack measuring system and its application to obtain crack growth rate data from centre-cracked-tension specimens. Details of the hardware and the software are included and the method and results fo the calibration for this type of specimen are given. Keywords: Direct current; Crack measurement; Computer applications; Crack propagation; Electric potential. (Australia).

Book Description
Currently adopted manual distress surveys involve a high degree of subjectivity, low production rates, and exposure to hazardous conditions. FDOT has acquired and validated a multi-functional survey vehicle (MPSV). However, when an automated crack distress survey operation is complete, FDOT must also use a reliable, accurate and speedy mechanism to analyze the distress information obtained from the survey. A number of automated and interactive crack measurement systems are available to assist pavement engineers to objectively evaluate pavement cracking from digital images of the pavement survey. Based on the findings of this research project the investigators found two such software packages which have the ability to function in conjunction with the imaging and inertial sub-systems of FDOT's MPSV and procedure repeatable and speedy distress evaluations. Of the two software that were studied in detail, namely, the Crackscope Program and the Workstation Program, the latter is more compatible with the MPSV.

Book Description
The Special Issue “Non-Destructive Testing of Structures” has been proposed to present the recent developments in the field of the diagnostics of structural materials and components in civil and mechanical engineering. The papers highlighted in this editorial concern various aspects of non-invasive diagnostics, including such topics as the condition assessments of civil and mechanical structures and the connections of structural elements, the inspection of cultural heritage monuments, the testing of structural materials, structural health monitoring systems, the integration of non-destructive testing methods, advanced signal processing for the non-destructive testing of structures (NDT), damage detection and damage imaging, as well as modeling and numerical analyses for supporting structural health monitoring (SHM) systems.

Book Description
Held every four years, the International Congress on Fracture is the premier international forum for the exchange of ideas between scientists and engineers involved in producing and using materials resistant to fracture and fatigue. This major six-volume work which forms the proceedings of the Seventh International Congress on Fracture therefore provides the most comprehensive account available of the current status of research into fracture and fatigue, and the application of this knowledge to the design, fabrication and operation of materials and structures. As such, it will be an essential reference for materials scientists and mechanical, structural, aeronautical and design engineers with an interest in fracture and its prevention.
