Chapter 6a – Plane Stress/Strain Equations
Chapter 6a Plane Stress/Strain Equations Learning Objectives To review basic concepts of Plane stress and planestrain. To derive the constant- strain triangle (CST)element stiffness matrix and Equations . To demonstrate how to determine the stiffnessmatrix and stresses for a constant strain element. To describe how to treat body and surface forcesfor two- dimensional 6a Plane Stress/Strain Equations Learning Objectives To evaluate the explicit stiffness matrix for theconstant- strain triangle element. To perform a detailed finite element solution of aplane stress 7/8117 Chapter 6 - Plane stress / Plane strain Stiffness Equations - Part 11/81 Plane stress and Plane strain EquationsIn Chapters 2 through 5, we considered only line elements.
The two-dimensional element is extremely important for: (1) Plane stress analysis, which includes problems such as plates with holes, fillets, or other changes in geometry that are loaded in their plane resulting in local stress concentrations.
