Reported in this paper are recent developments to improve optical creep strain measurement to achieve a 65 microstrain accuracy level with an error of less...

... finite element numerical analysis was also performed. Data on plastic limit moment is obtained from load-displacement and load-strain responses. The results indicate that plastic limit loads determined by test (including displacement and strain measurements) and finite element analysis are in agreement...

Neutron-diffraction strain measurements are non-destructive and capable of tracking the development of the elastic strain field as a function of applied load in a single specimen. This paper presents two demonstrations of neutron-diffraction strain-scanning with high spatial resolution...
