Single-axis combined shearography and digital speckle photography instrument for full surface strain characterization [PDF]

, 2005
Full characterization of the surface strain requires the measurement of six displacement gradient components of the surface strain tensor. The out-of-plane displacement gradient component may be directly measured using the full-field speckle ...

Neutron Diffraction Measurements of Residual Stresses for Ferritic Steel Specimens over 80 mm Thick

Metals
The maximum thickness for ferritic steel specimens’ residual stress measurements using neutron diffraction is known to be about 80 mm. This paper proposes a new neutron diffraction configuration of residual stress measurements for cases that are over 80 ...

Strain Test of Farm Machine Chassis

, 2010
During the construction of self-propelled and tractor-pulled farm machines several tests take place in laboratory and in the field. The functional and the stress-strain tests are mostly used. The mechanical load on the chassis is derived from the load of

A Crack Detection Method for an Insulator Based on the Optical Frequency Domain Reflectometry Fiber Sensing System

Photonics
In this paper, a method for detection of crack locations and the width of basin insulators is proposed. Based on the optical frequency domain reflectometry (OFDR) system, the system utilizes an FBG with high feedback for strain as well as temperature ...
