CrystalPlasticityStateVariable

Description

CrystalPlasticityStateVariable represents a state variable, such as dislocation density in crystal plasticity system. The initial values of this state variable are either provided in the input file readInitialValueFromInline() or read from the file readInitialValueFromFile(). The state variable evolves as $var element = document.getElementById("moose-equation-918b381f-41ef-4afd-a66a-664f665adfd4");katex.render("y_{n+1} = y_n + \\dot{y}\\cdot dt $ where $\\dot{y}", element, {displayMode:false,throwOnError:false});$ is the state variable evolution rate. The $var element = document.getElementById("moose-equation-03b08fdb-3880-405d-bc93-0a89cc9c6cfb");katex.render("\\dot{y}", element, {displayMode:false,throwOnError:false});$ can have multiple components, such as $var element = document.getElementById("moose-equation-93437208-6661-4683-b993-f60256c19dc4");katex.render("\\dot{y} = a_1 r_1 + a_2 r_2 + \\cdots", element, {displayMode:false,throwOnError:false});$ where " $var element = document.getElementById("moose-equation-8578328d-a04a-4da9-9e10-38197d9fa9eb");katex.render("a_1, a_2, \\cdots", element, {displayMode:false,throwOnError:false});$ " are the scale_factor and $var element = document.getElementById("moose-equation-7f34f5c7-261b-4d08-8784-e9c1e5e8f298");katex.render("r_1, r_2, \\cdots", element, {displayMode:false,throwOnError:false});$ are the individual rate components.
