Estimating and Measuring Methods of Residual Stresses Using Inherent Strain Distribution Described as Functions(Report 1). Expression of Inherent strain in Form of Function and Its Estimation.

QUARTERLY JOURNAL OF THE JAPAN WELDING SOCIETY, 1993
When three dimensional welding residual stresses are measured based on inherent strains using Finite Element Method, too many inherent strain components in elements have to be specified to express their distribution. If these are determined experimentally, measurements of elastic strains must be made for points more than the inherent strain components.

Developed Inherent Strain Method Considering Phase Transformation of Mild Steel in Line Heating

Journal of the Society of Naval Architects of Korea, 2004
The inherent strain method is known to be very efficient in predicting the deformation of steel plate by line heating. However, in the actual line heating process in shipyard, the rapid quenching changes the phase of steel. In this study, In order to consider additional effects under phase transformation, inherent strain regions were assumed to expand.

Optical visualization of the full-field swelling of laminated rocks

Scientific Reports
Swelling laminated rock exhibits inherent anisotropy due to the preferred orientation of mineral grains and/or cracks which consequently impact its deformation behavior in terms of strain distribution and crack pattern during water–rock interaction (WRI).
