CFVR3703 - Effective stresses
Effective stresses on a 2D Model with irregular mesh.
A plane model is used to analyze the effective stresses obtained when applying the seepage results on a structural analysis.
The seepage model is a 5.0m x 6.0 m rectangle and the structural model is a is a 5.0 m x 10.0 m rectangle.
Element types used in the model: PLANE42 Needed CivilFEM Modules: |
