Out-Of-Plane Pressure

Apply pressure in the out-of-plane direction in 2D plane stress or generalized plane strain models

Description

The OutOfPlanePressure kernel applies an out-of-plane pressure value in the out-of-plane direction of Generalized Plane Strain or 2D plane stress problems. Either a function or a postprocessor can be used to specify the value of the out-of-plane pressure at each quadrature point. $(1)var element = document.getElementById("moose-equation-f40feded-0e70-4116-89c3-04eafe6ce139");katex.render(" P = f \\cdot \\hat{n}", element, {displayMode:true,throwOnError:false,macros:{"\\pf":"\\frac{\\partial #1}{\\partial #2}"}});$ where $var element = document.getElementById("moose-equation-11c775d0-4ea2-4c92-8292-cc47eb422dc6");katex.render("P", element, {displayMode:false,throwOnError:false,macros:{"\\pf":"\\frac{\\partial #1}{\\partial #2}"}});$ is the computed pressure, $var element = document.getElementById("moose-equation-27c6db3c-62f0-4d59-b4b4-3551b0404694");katex.render("f", element, {displayMode:false,throwOnError:false,macros:{"\\pf":"\\frac{\\partial #1}{\\partial #2}"}});$ is the function or postprocessor value of the pressure to be applied, and $var element = document.getElementById("moose-equation-6bfb6c5b-fb0e-429a-88ce-61730f092082");katex.render("\\hat{n}", element, {displayMode:false,throwOnError:false,macros:{"\\pf":"\\frac{\\partial #1}{\\partial #2}"}});$ is the unit normal vector to the out-of-plane surface. Following the convention of the Pressure boundary condition, the unit normal vector is considered to be positive when pointing inward towards the surface.
