It's not temperature, but this quantity has a linear relationship with the relative wavelength shift of a fiber Bragg grating. Tuning this quantity can greatly increase the spontaneous polarization and transition temperature of a ferroelectric thin film. This quantity's time derivative is the symmetric component of the gradient of the velocity field. This quantity's value is constrained by the Sai
It's not temperature, but this quantity has a linear relationship with the relative wavelength shift of a fiber Bragg grating. Tuning this quantity can greatly increase the spontaneous polarization and transition temperature of a ferroelectric thin film. This quantity's time derivative is the symmetric component of the gradient of the velocity field. This quantity's value is constrained by the Saint-Venant compatibility equations. This quantity is the independent variable of Hollomon's equation, in which it is raised to a namesake "hardening" exponent. A common device for measuring this quantity consists of a patterned strip of constantan alloy connected to a Wheatstone bridge, which gives this quantity as the relative change in resistance divided by the gauge factor. This quantity is localized when necking occurs, and it lies on the x-axis of a curve whose slope equals Young's modulus in the elastic region. For 10 points, name this tensor quantity that measures the local deformation of a body in response to stress.
