CZMComputeDisplacementJumpTotalLagrangian

Compute the displacement jump increment across a czm interface in local coordinates for the Total Lagrangian kinematic formulation

Overview

The CZMComputeDisplacementJumpTotalLagrangian calculate the displacement jump across a cohesive zone in the interface natural coordinate system. This object assumes finite strains and does account for the interface rotation caused by deformations or rigid body motion. The displacement jump in global coordinates is defined as: $var element = document.getElementById("moose-equation-a933aaaa-e2d5-4b2a-bf23-59694344488f");katex.render("\\llbracket u \\rrbracket = u^+ - u^-", element, {displayMode:true,throwOnError:false});$ and is related to the the displacement jump in interface coordinates, $var element = document.getElementById("moose-equation-7e54a831-4b67-44a8-bbe2-92cd337d118b");katex.render("\\llbracket \\hat{u} \\rrbracket", element, {displayMode:false,throwOnError:false});$ by the the following expression: $var element = document.getElementById("moose-equation-68a14d03-be28-41f5-8c48-3fda1c09a687");katex.render("\\llbracket \\hat{u} \\rrbracket = Q^T_0 R^T \\llbracket u \\rrbracket", element, {displayMode:true,throwOnError:false});$ In the above expression $var element = document.getElementById("moose-equation-68cd00c8-51af-4d87-8d8a-0626bfa4fec1");katex.render("Q_0", element, {displayMode:false,throwOnError:false});$ is the rotation matrix transforming from global to local coordinates in the initial configuration, and $var element = document.getElementById("moose-equation-b17b42b3-98ee-4bbb-8f32-639a01949e60");katex.render("R", element, {displayMode:false,throwOnError:false});$ is rotation matrix associated to the interface deformation gradient, $var element = document.getElementById("moose-equation-2b685886-aa24-4e80-97da-229bd35d37ab");katex.render("\\hat{F}", element, {displayMode:false,throwOnError:false});$ . The first component of $var element = document.getElementById("moose-equation-dd9ff600-0da6-43e9-8381-4420bb8191c1");katex.render("\\llbracket \\hat{u} \\rrbracket", element, {displayMode:false,throwOnError:false});$ always refers to the displacement jump in the normal direction, the other two components refers to tangential directions. This object can be used in 1D 2D and 3D simulation.

Example Input File Syntax

This object is automatically added from the Cohesive Master Master Action when strain=FINITE.
